Windows Phone 7.8 Update

Forcing the Windows Phone 7.8 update: Camera button not required but patience is

If you've checked your Windows Phone 7.5 device for the 7.8 update with no success, you may want to try to force the process, just as we did with other Windows Phone updates like Mango.

This is a little different than downloading and installing Windows Phone 7.8 manually, which we reported on earlier. With this method you're basically tricking the Microsoft servers to recognize your Windows Phone and initiating the update early. Think of it as cutting in line (and Microsoft is okay with this, no worries).

The other benefit with this method (versus the CAB one) is it means you are getting the official carrier/OEM update that usually includes the firmware too. If using just CABs you are updating the OS but not any device specific software. That's not a bad thing but it's really not ideal. 


How to

Forcing requires patience and the ability to disconnect your computer from the internet. Make sure you have the Wifi and your data connection turned off on your Windows Phone and connect to Zune.  Go to settings and check for an update and as soon as you click the "Update" link in the settings you'll need to disconnect from the internet.

Let Zune come back and tell you that it can't check for an update right now, reconnect to the internet and you should see that an update is now available. Timing seems to be key and it may take you a few tries to get things just right (took me six tries).  From there you follow along with the update wizard and your Windows Phone is updated.

Windows Phone Updates

If this trick doesn't work, it likely means that the update files for your device aren't out there on the servers yet to be installed.  We were successful in forcing the update on the AT&T Nokia Lumia 900 but couldn't get the HTC HD7S to update.  When all was said and done, the Windows Phone version ended up being 7.10.8858.136.

Interesting note on the 7.8 update is that it provides support for devices without a camera button. More than likely this is for future low-end devices like the Alcatel One Touch where the lack of a camera button will keep production costs down.  You may see this in a smaller update that installs before the 7.8 update goes through.


Step by step instructions to force the Windows Phone 7.8 update

  1. Connect your Windows Phone to a PC and launch the Zune software
  2. Click on Phone > Settings > Update. Allow the software to tell you whether an update is available. If so, skip this guide. If not continue to the next step.
  3. Time to force the update. Click another button (any of the options above or below the word Update). Then click the Update button again, and this time disconnect your computer from the internet after 1-2 seconds. Do this by pulling out the Ethernet cable, disabling Wi-Fi, etc. If it says your phone is already up to date, you didn't disconnect quickly enough and need to try this step again.
  4. Wait 30 seconds or so and Zune should display a notification that an update is available.
  5. Now reconnect to the internet and continue with the update process through the Zune software.
  6. Depending on what OS build you are starting with, you may be prompted for several OS updates
  7. Let the phone update and wait. The final OS build is 8858. If you are getting just 8779, you'll want to repeat 1-4 above
  8. You may also be prompted to install a firmware update at the very end, follow through with this
  9. Celebrate! The whole process, including backup could take up to 60 minutes. Check that you are on build 8858 to see if you are done.


What if this method just doesn't work?

This won't work for every Windows Phone out there, only those that are officially designated for the 7.8 update, so your experience will vary.

If you don't get the update, it can mean one of two things.

  1. Your software update is literally not on Microsoft's servers for your phone/carrier. Try again in a few days.
  2. Your update may never come.

On the second point, we're not too confident generation one devices or Sprint's Arrive will ever "officially" get this update, which is why try as they might this method will never work. For you folks, you'll have to do the more tricky manual CAB method.That will do the job but obviously it won't include any firmware. C'est la vie.

Let us know in the comments if you've had success with the forcing trick to get the update.

Goddamn Zune simply refuses to connect to the update servers. Help, anyone? I've got an unlocked, unbranded Lumia 710 in India.
EDIT - Zune is stuck on "Checking for updates". Has been for ten minutes now. Extremely infuriating, this.

chataddicted says:

if u failed just go to nearest nokia care... they update ur phone..... dont forget to give me a thanks bro. im also fm india...

They do? Okay, I'll look into that. They're a bunch of weasels though, the Nokia Care guys. They'll probably charge me for updating the OS. :\

chataddicted says:

no its free my friend updated last month fm them. he is using lumia 610....

TKETZ196 says:

Has anyone tried this method for an HD2 that has a WP7 custom ROM on it? if so did it work? i would prefer not to reflash my device. I am still on 7.5 build 8107.

avail1236 says:

tried for a long time with verizon trophy and wasn;t able to get it.

vishalrajani says:

ok guys, i got the update, iam going to write what worked for me..
the usual force update steps but, dont remove your ethernet club or switch off your router, disable wifi through your laptop/pc- adapter settings- disable wifi. Your phone should always be in flight mode. Be quick and fast in disabing, i only had to do it twice.
secondly there are 3 updates, you have to repeat the whole procdure for all the 3 updates.
my phone is restarting at present waiting for 7.8
Factory unlocked
Htc Radar/Omega

PutoPolyo says:

thanks a lot! worked for my lumia 800 in the philippines after several tries.

Dannay says:

can't seem to get it working :( Unlocked HTC HD7, keep trying but i either don't pull it out quick enough or i pull it out and then wait for around 20 seconds and says can't check for updates now, please try again later.  in small print says couldn't connect to update service :(
so annoying seen as i was easily able to force update for mango :/

Spiddelito says:

Just keep trying! Updated my unbranded HD7 yesterday using the Zune cable trick. Had to do it 3times for 3 updates. It's out there. Works like a charm by the way.:-)

Dannay says:

Hi, wow lucky i tried for a bit today and still couldn't do it, so annoying i forced mango really easily ive lost the nack :/
is unbranded the same as unlocked? as mine was locked to o2 but ive unlocked it
and wow damn this will be well hard if i get it right to do three updates!

jan-ii says:

just got it working on my GF's lumia 610 ! update in progres.....

Skaterbuoy says:

Although I have used the remove cable trick for previous updates and two out of the three updates required for 7.8 this time, I've just not been able to get the final most important update to work. God have I tried for long enough!
So thanks to Robin for his guide, although doing basically the same thing, as ripping out the cable it worked on the second attempt. Bingo.....
I guess its all down to timeing! Let me repeat his comments for others
1. Connect your device and open zune
2. Open command prompt and type in: ipconfig/release (Do not press enter yet)
3. Press in Zune "Update"
4. wait about 4 seconds and press in Cmd Prompt "enter"
5. Zune will a update
6. Type in Cmd Prompt ipconfig/renew
7. Follow the steps in zune "enter"

inked18 says:

worked for me on my unlocked C900b I rebranded it to rogers dont know if that made a difference but the cable trick did not work at all this worked first try good thinking!!

inked18 says:

rebranding definately made the difference I did the first 2 updates rebranded to rogers then tried the 3rd update unbranded and it wouldnt work at all rebranded back to rogers and it worked again first time...just FYI

RobinPaul says:

Well got the update to force, but now it's not downloading it... been for 10 min on step 2 of 10: 0%..... what to do?

chataddicted says:

just wait this is probably for ur network and comuter... dont do anything foolish like shut down or unplug data cable...

RobinPaul says:

well i cancelled it, cause it didn't do anything for like 30 min + :(, going to try and force again

Bogdan Badea says:

Worked for my Lumia 800 romania country variant. After 10 or so tries I got the right timing (about 6 seconds) and then got it from the first try for each of the three updates. Initial impressions are good, although it does feel a little bit more laggy in the start screen! I'm also a bit dissapointed that the Xbox Live games are still not available for my country (after reading in one of the update's description that the Live Service would be extended in a few countries)
P.S. Being a developer myself, I BET this "forcing" stuff is left intentionally in the Zune software ;)

caxa says:

I have a doubt about this forcing method.
Do I leave my celluda data / wifi ON or OFF?

ilgulamc says:

Finally updating to wp7.8! I couldn't go past the first update.. After 50 trials of cable tricks I decided to turn the modem off in order to change my ip address and guess what... it worked! So if you are stuck like me after the 8779 update, try to renew your ip address.
Whating for the install to finish to be another happy 7.8 user :-)

AmiTimA says:

Thanks dude ! I changed the ip address using this link:
and it worked like a charm.

caxa says:

Thank you! 
But is it normal to get "Can't check foir updates right now." even if I don't turn the internet off?
This happens when I turn OFF both cellular data and wifi on my cell..

Ethan J says:

This is exactly what happens to me, as soon as I turn off both WiFI and Data my phone will refuses to check for updates instead giving me errors 8000FFFF and 80072FA8 and says  connection cannot be made depiste my Ethernet being in and working

Mathiew24 says:

Got it on my old Samsung Focus had to do three updates before getting the big one! Almost done installing its too bad i dont use this phone anymore got a Samsung Galaxy S3 now.

Mike Fait says:

What carrier?

Unknwnxix says:

this trick worked for me after like 20 times of doing it was about to give up

Dannay says:

Does anyone else keep getting cannot connect after like 30 seconds of looking once disconnected?

Walkerboy79 says:

Yeah, I got that too. Just means you disconnected too fast still.  Just keep trying to time it out and wait a second longer each time.  It would check for updates for up to five minutes for me and then my update was finally available.

Dannay says:

ok thank you, ill try that

Walkerboy79 says:

Worked great for my lumia 900 on Rogers in Canada.  Got 3 updates total: 8779, 8783 and 8858.  Took me 2-5 tries for each of the 3 updates to get the timing down.  Like was said in earlier post.....if you see message "can't update now" then you disconnected internet too fast.  If you see "phone is up to date" then you disconnected too slow.  Try hitting not disconnect.....and count the seconds to the message "phone is up to date." With my connection it took 5 seconds. Then click different link above update.....then immediately click update again.  I tried to pull the dsl cable from modem at about 3 sec. after hitting update again.  I just aimed for the middle.  Sometimes I was too fast and sometimes too slow.  But I now have all my updates.  Hurray!!  
LOL, don't forget to plug your dsl(internet connection) back in when update is available.  I lost an update because I got excited when it worked, and forgot to plug it in.  Oh, and on repeat tries, give the internet 30 sec before hitting update again as the connection speed may vary just a bit after plugging in again.  Good Luck!

wpguy says:

Any success with any HD7 on TMo US? If yes, is your phone unlocked?

Chef316 says:

No luck yet! I have a Locked HDC HD7 on T-Mobile US

PicodeGalla says:

I have an unlocked HD7 for 2+ years now, no update yet and I too have tried the trick.  Worked like a charm with mango but not this time around.  Side note, really dissapointed with Tmob, they have great prices but not impressed by their windows phone 8s, really want a L920 but just can't afford the $60+ dollars a month that ATT will charge me.  Also not convinced with the 8x considering th issues I have had with my HD7 (wifi/3g bug connectivity, when listening to music on headphones, volume will increase or decrease or ask me to speak into the microphone)  

ldp247 says:

For us Verizon/Trophy users, we are just screwed until they decide to let us have the update.  I've seen the European Trophy users have been able to use the cable trick with some success.  I'm just going to wait until I'm notified that an update is available for my phone.  I don't understand the reasoning of leaving out the US Trophy.  This is one of the issues with MS.  Making the wrong decisions just like Android and IOS.  They could have sent out the update to everyone at the same time.  Don't give me it could have shut down the servers, when that's BS due to when I had a BlackBerry, any major updates, they would send it to your computer and your phone would notify you that there is an update.  Then the message would instruct you to go to your desk top client.  That was one of the things that I did like about BB.  Very diligent with mass updates.  I'm not leaving or even bashing MS, but this is not the way to handle things when you are still trying to gain a foot hold in the mobile industry.  But I will have to be more patient than normal until my phone or plug into Zune to get the update the old fashion way.  By waiting.   Congrats to all that were able to download 7.8.  Enjoy.

FW190D says:

Dude, please chill. It's the carrier you should be bad mouthing not MS. As you can see, this is MS pushing the update, not the carriers. I have HTC 7 Pro, HTC said "not yet", but I got it anyway, thanks to MS.  Don't get paranoid about Europe vs US strategies, like so many others.

ldp247 says:

Listen, that shows that you didn't understand what I was saying nor did you read what I said.  I wasn't bashing MS and secondly I wasn't being paranoid about Eu vs US.  I was just voicing my opinion.  I completely understand that it's the carrier, but the point I was making that MS shouldn't leave it to the carriers to say when an update should go out to the customers.  What that does is makes people want to leave the os for something else.  I am one of the strongest defenders WP and MS.  I merely stated that a route that MS could go is to send the update directly to the desktop app, that way people wouldn't have to force an update or trick the servers into thinking that your device is ready for an update.

freerider189 says:

Anyone been able to get this update with a phone on T-Mobile/EE in the UK? I've got an Omnia 7 with them and I can't seem to get this method to work.

RobinPaul says:

how long does the downloading files take? (the one STEP 2 OF 10: Downloading Updates...0%)

caxa says:

Yeah, finally updating my Samsung Focus v1.3..
It is ATT-US but I changed to ROG-CA, I don't know if made any difference..

koffey says:

How did you change the carrier?

cyber_k9 says:

I'd also love to know how you do this.  What I've read seems to imply there's a registry-editor you run on the phone itself - not the Windows desktop registry - (after deploying with a sideloader on a developer-unlocked phone?)... but I can't find the XAP in question to do this?
Or am I mistaken and there's another way?
Thanks. :)

djay_434 says:

Tried like update yet for Lumia 800 in India :(

Kumar Ankit says:

Nokia phone in India need not try the force method. Visit the nearest Nokia care center to get the update installed.

md_minhaj says:

No luck for my omnia w even after almost 15 tries!! India.

codytrahan35 says:

been trying for about 2 hours now on my focus, at&t US with no luck. netflix is losing my attention, almost time to give up.

Dannay says:

I so don't get why i can't do this been trying for 2 hours ill give up and try another day.. i don't know if like its because the server is busy when i search the error code i get it says the windows update server may be busy but that is aimed at windows not windows phone :/ plus saying my phone is updated it does fine :/..

codytrahan35 says:

5 secinds is too long and 4 seconds i get the cant connect try again message lol

Scatty69 says:

any info on bluetooth share,ringtone maker,google search...?

RobinPaul says:

how long does the downloading files take? (the one STEP 2 OF 10: Downloading Updates...0%) >>>> On that step for 45 min with 0%, like WTH???

vinca andrei says:

20 min, 3 updates

RobinPaul says:

yeah, well im at update 3, but it's says downloading update...0% for almost 1 hour now -_-

vinca andrei says:

hmm.. It takes about 5 min

RobinPaul says:

that's what i thought too, so now I don't know what to do with it, let on or try restarting phone and zune and force update again?

vinca andrei says:

Can you try to disconnect (and connect again) your computer from the internet?

RobinPaul says:

still nada :(, this just sucks...

vinca andrei says:

I think you have nothing to lose. The update itself has not started yet, so you can`t break your phone ( I hope ).  The last step is to unplug the USB cable, and try the update again

RobinPaul says:

yes, restarting Zune / Phone and trying again

RobinPaul says:

ok, i restarted Zun and Phone and unplugged it and got the forced update, but still hanging at 0%, seriously why :(

vinca andrei says:

That`s strange. What phone are you using? Are you on Proxy or VPN?
If nothing works, and you really want this update you can try a deepshining version here: . A friend tested on a HD7 and it`s working great. It`s developer unlocked too.

RobinPaul says:

I'm using a Nokia Lumia 800, going to keep trying, have to install this update.

RobinPaul, I'm on a fast connection (70mb) and it took a a few seconds, but it should not take that long even on a slowish connection.... Did you reconnect your PC to the internet?, if not you might be downloading the update over your mobile connection. I could be wrong though as you shoudl really turn mobile data and wifi off (onthe phone) before you start.

RobinPaul says:

yes, i plugged the ethernet cable back in and phone is in Airplane mode. So i seriously don't know what the hell is taking it so long :/

vinca andrei says:

Working with my HTC HD7 in Romania

FW190D says:

super tare! Se pare ca romanii nu au probleme cu update-ul.

vinca andrei says:

O tara ca Romania nu putea fi evitata :))

wpguy says:

If I have my TMoUs HD7 unlocked, will I get the update? From reading the last 600+ posts, hard to tell if the HD7 owners getting the update are outside the US or if they are on TMoUS with an unlocked phone.

koffey says:

I have tmobus hd7 unlocked, running it in Canada on Wind, but cannot get the updates....  I was under the impression that MS was bypassing all the carriers, but it appears that this isn't the case, if it was, then TmobUS HD7 would get the updates like other HD7s.  Bell, O2 and others have their updates...

wpguy says:

I am thinking the exact same thing, that Microsoft is not bypassing all carriers. They might have done a behind the scenes coordination of most carriers, but clearly not everyone is getting the update.

All I get out of TMoUS on Twitter is "No news on the update," "We have no official news to share," and "Our newest information is at This link will update when a new version is available."

MarkCwee says:

Updated my HTC HD7 just like described in tutorial.
Wait for about 10 seconds and disable the network adapter. Succeded after 5'th attempt.

No delays on my Lumia 900 ATT

FW190D says:

It works on unlocked HTC Arrive like a charm. I like the new interface and since it is such a beautiful phone, wp8 can wait as I'm holding on to this one.

Pelatz says:

How?!?! I've been trying for days. You follow the steps Verbatim? Maybe it's a regional thing. I'm from South Texas.

FW190D says:

I bought mine some time ago, was never locked or attached to any plan. Don't know why yours does not work. Did you manage to get the update? I just followed the usual steps.

Pelatz says:

I sat in front of my computer & zune for about 2 hours/3 days straight unplugging & replugging, restarting zune, & variations of the trick based on other's comments, but still nothing.  Very frustrating.

FW190D says:

Sorry to hear that. I guess you have to wait until you get it by the carrier. What happens exactly?

Pelatz says:

After disabling WIFI/airplane mode on phone, I plug it in & open zune on my desktop. I select update & receive "phone is up-to-date" message, which is 7.10 (7720). I select another option, then back to 'update,' then I immediately disable ethernet port or physically unplug the ethernet cable from MOBO. It doesn't matter whether I wait 1, 2, & 3 seconds or immediately unplug/disable ethernet, the result is the same: "Can't check for updates right now, try again later." Waiting beyond 3 seconds to disable/unplug internet results in "phone is up-to-date message." I've timed the wait before I unplug/disable internet & it never goes beyond 3 seconds, even after I restart Zune. My phone isn't unlocked, so maybe the problem is Sprint's got a vice grip on non-unlocked phones getting the update. I'm gonna keep trying, but I won't try the CAB/seven-eighter thing until my contract expires in mid-April. At that point I'll decied to either wait until August or switch. Thanks for the help though.

FW190D says:

Well ,you can also try toggling the enable/disable ethernet port until you get an answer.. That's how my first update kicked in. Hope it helps.

chronochaser says:

This worked for me last night!  Nokia Lumia 900 on AT&T. Fabulous!

nkilin9 says:

Appreciate the tip! Worked on my Lumia 900 which I bought unlocked. It appears the update did not wanted to come easy, so I used the "forced" method described above and after the 4-th try the update was prompted :D really timing is important, also note that I have removed the SIM card from the phone and removed the screenlock.

The Zune trick worked (after a couple of tries) on my Lumia 800 and a Lumia 900 in Luxembourg. To get it to 8858 it took 3 updates on the L800 and 2 on the L900.

jonharrell says:

I have been trying to talk to AT&T about timing on when phone other than Lumia will get the update and all I freakin get is "sorry for the inconvenience"

From my twitter

We are all go in NZ. Lumia 800 on Vodafone. Update trick worked a charm (took 5 goes - 6 seconds after clicking update, turn off wifi)..
So glad MS have finally got the updates working properly.

scdkad says:

Wow-over 700 comments and lots of stress and anxiety over an update that brings practically nothing!

Pelatz says:

scdkad, nobody likes a negative nancy. just saying.

RobinPaul says:

well im giving up on 3th update, im stuck on Step 2 of 10: downloading Updates ... 0%, it's won't get passed 0% for some reason and don't know why -_-

AmiTimA says:

Same here. Did you find any work around?

scdkad says:

Wow-700 comments and lots of stress and anxiety over an update that brings.....practically nothing!

it's a useful upgrade that maximises the use of space in my start screen.
you just sound like a bitter person. struggling to make and keep friends?

scdkad says:

Definately not bitter and have lots of friends. What are you getting at?
Read my lips-this update brings nothing but new colors and tile sizing. Major fail on MS's part when there are so many things they could have brought but pretty much gave all of us early adopters the middle finger.

ShipWreck says:

Yeah I used the Zune trick to get the Mango on my Arrive but man this time around I had not luck I either get the device has the latest update or there not internet connection. Will try later.

Jakeway says:

It seems to get Ringtone maker and Bt to work you need: Fireware: 1750.0823.8858.12460
But it doesnt seem as if yo can force thus update as once Zune see you're on 7.10.8858.136 it doesnt look for more updates.
What can be done about this?  :(


Got it after second trie thanks!
Lumia 900 ATT&T 

PCCalixto says:

Worked perfectly

monigal2 says:

I'm so ready for that update!!

Majin_Static says:

What about Mac users? How would we go about this without the zune software.

Im on a mac using vmware

I used this method on my HTC Titan,, waited for a count of 1,2,3,4 before disabling my network connection. I did this and updated three times and eventually got to 7.8. Hope this helps someone else.

djdoubt03 says:

Titan or Titan 2 just want to mak sure

jchapman01 says:

AT&T or Unlocked?   I think that makes a difference. Also what city/ state?

Sam Not Spam says:

Just did it this morning, and redid my start screen twice :)
So, consider that a confirmation for Hawai'i on AT&T, Lumia 900.

ShipWreck says:

Error 8007EFF or Phone already updated they could make this easier if they would just push the update out like a normal one.

Stupidentist says:

I can confirm this nifty little trick is working for the HTC Radar 4G. Just finished the third and final update!

ShipWreck says:

Anyone have any luck with their Arrives??

Pelatz says:

A couple of dudes have, yesterday & day before, apparently.  Don't know where they're from though.  I've been trying since day one, but I haven't been able to get it to work no matter what I try.  South Texas.

AzmoD3uS says:

After failing to make the cable trick work yesterday, i tried again today and to my surprise, the cable trick worked! Either the update only started to make its way to the servers today, or i was doing something wrong yesterday!
But anyway.... looking forward to 7.8 on my HTC 7 Mozart!!!

heffyrabbit says:

Finally got the update after 3 updates:
Lumia 800, unbranded here in the UK on Zune in Windows 8.
I believe the trick is to know how fast the server responds to an update query. I get a response in about 6 seconds. Therefore I pull the LAN cable at about 4 seconds after clicking UPDATE. If i get no response after about 7 seconds, I push the LAN cable back to restore the internet connect and pull it out again in about 5 seconds. I keep repeating until the update shows up. Hope this method help others who hasn't been lucky.

Works in Australia. I have a Lumia 800 on Optus and it worked. Had to turn off the wireless on the phone after 5 seconds not the laptop though.

codytrahan35 says:

i, gonna go on a limb and guess it hasent hit the servers for focus in the US. im unlocked but only have an att sim, ive been trying all day and no luck.

sydnic says:

Worked for me ! Nokia 800 , Telus , Canada. 3 updates required. After each update, unplug phone, restart zune,plug phone in again, do the dance again as instructed in the article. Worked like a charm

Tato1979 says:

Hi all! Just signed inst this comment. Lumia 710 for Movistar Argentina, I was able to force the update just like WPCentral advices!!! I'm already running WP7.8! Is just a matter of timing, which I "mastered" reading advice from lots of other members. Thing works like this, airplane mode in the phone, plug tu computer, Zune starts. Go to settings, click update, and the count to 3 or 4 and cut the wifi. If it worked, instead of the "can't check right now", you'll get "Update available for your device" (if not, you get the can't check... stuff. Keep trying, is a matter of timing). Reconnect to the wifi, and click on update. It can give you just one update (three in total), if so, you'll have to repeat this two more times. During the whole process time (I mean, while you try to nail the wifi-off "game"), don't let your screen lock, I mean, keep your tiles always visible, don't let the phone lock.
Worked great for me! Hope the same for you all. Thanks to WPCentral and it's members for the help! Time to enjoy my "new" phone!

I solved this by creating a script in EventGhost. The script is pasted below:
<?xml version="1.0" encoding="UTF-8" ?>

<EventGhost Version="1610" Guid="{41074DC0-C41D-4F73-91FE-EE4F5237AF57}" Time="1359678003.07">

    <Autostart Name="Autostart" Expanded="True">

        <Plugin Identifier="Keyboard" Guid="{59CBD10F-C1D8-4ADB-999B-9B76BA360F1F}" File="Keyboard">




    <Macro Name="Emulate Keystrokes: {down}" Expanded="True">

        <Event Name="Keyboard.LCtrl+R" />


            Window.SendKeys(u'{down}', False)



            Window.SendKeys(u'{enter}', False)






            System.Execute(u'stopp.bat', u'', 0, False, 2, u'', False)






            System.Execute(u'start.bat', u'', 0, False, 2, u'', False)





Save as something.xml on your desktop and load in Event Ghost.


Use: Open Zune and connect your phone as all the other posts here have mentioned. Replace all the Start Application actions with the start.bat and stop.bat files on your own system. In Zune, click on the entry above the ''Update" in settings (mine is in Norwegian, so I don't know what yours will be called). Then, while EventGhost is in the background, launch the batch process with LCtrl+R. The batch will now press arrow down and select "update", wait 5.5 seconds and then disable the network adapter before waiting 5 seconds to enable it again.


You might need to adjust the initial pause action depending on your system.


This script is dependent on two files on the desktop: A start.bat script that contains


netsh interface set interface "Wi-Fi" ENABLED


and a stop.bat that contains


netsh interface set interface "Wi-Fi" DISABLED


Note that the quoted text (Wi-Fi) is the name of your network adapter. Also, these lines of code needs to be executed with administrator priveliges on your computer. This is dependent on your environment and I will leave it up to you to figure it out (hints: group policy -> Run all administrators in administrator mode somethingsomething: Disabled. Remember to enable after!)

UK / Lumia 710 / VodaFone  - Update required FORCE TRICK in ZUNE - but updates fine to 7.8

daddyex12 says:

i have a htc titan 2 and i have no luck yet. i will keep trying.. :(, how do i get th pop up? after i disconnect?

davidblouin says:

Work, but why ? Does it prevent Santa from checking if your on the naugthy list ?

Dzuni22 says:

I was able to get the force update through zune by the way I'm from Austin (TX). Just as everyone had mention it about doing the force update is that (it takes some time and patience). I use this link from youtube to help me out on how to push the update. Hope this helps out!

Windows Phone 7.8 on AT&T Lumia 900. Steps to get the update is in the video. Comment any questions im here to help!! Here are the steps to update-
1. Connect your lumia to zune, and put the phone on airplane mode
2. go into the "View sync options" on zune
3. have your internet connection window on your laptop open- youll need it for the next step
6. keep repeating step 4 until you get it to work. you will have to keep turning on the internet after each failed attempt. but trust me, it WILL work!

CarlM12 says:

Need some advice. I tried to force the update on my Nokia Lumia 900 last night. It worked or so I thought. It did not update to 7.8 so  I am assuming there was an update I previously missed. I decided to restore my phone to the previous saved backup and try again on1/31. Again no update available. I hooked my wife's phone up and it updated no problem whatsoever. I tried mine again and no luck. I even tried the force method again and I can't get it to work now. I have done nothing to my phone, but am stymied why my wife's phone would pick this update up and mine won't. Any suggestions?

ArtSooby says:

I succesfuly updated my devices to WP 7.8:
- Nokia Lumia 900 (Rogers)
- LG Optimus 7 (Telus) e900
- LG Optimus Quantum (Bell) c900

Anaba says:

It wont work for me. I have a Lumia 900, and it just keeps telling me it cant check for updates at this time when I try this trick

Completed all 3 updates just now. Nokia Lumia 900 Philippines here. Im so happy to finally got the update after almost 2 hours. I used a different trick posted here.
1. Connect your device and open zune
2. Open command prompt and type in: ipconfig/release (Do not press enter yet)
3. Press in Zune "Update"
4. wait about 2-5 depending on your connection (5 seconds for me) and press in Cmd Prompt "enter"
5. Zune will have either have up-todate, cannot connect to internet... or update available. It all depends on right timeing.
6. Type in Cmd Prompt ipconfig/renew if no update is available
7. Follow the steps in zune "enter"
I personally find this much easier and faster to do than unpugging the internet. Goodluck to those who are still trying..

Micfur says:

No luck updating my T-Mobile Lumia 710. I've been trying since yesterday with no luck. Guess the update isn't available for my 710 yet:/

xchaser says:

Are you on T-Mo USA? if so I think T-Mo USA hasn't sent the Update. I have a HTC HD7 and been trying the Unplug Trick with no Luck.

korg250 says:

I can now confirm that changing Samsung Focus to Rogers (canada) the disconnect trick works.
I am still at 8773, but have already made the two previous updates.
The timing to disconnect is crucial and totally depends on your internet speed.

p0ppyman says:

The trick worked for me on my Lumia 900 on AT&T in San Francisco Bay area. It took me longer than is should have because when I plugged the ethernet cable back in I was not waiting for the system tray network icon to say I had re-established connectivity before I tried the sequence again. Took two updates to get to 7.8. About 2 seconds was my wait time when pulling the plug.

djay_434 says:

No luck for Lumia 800 in India!! :(

rabit1 says:

HTC HD7 Unlocked/Unbranded Singapore.
Confirm. Downloading 3rd update now (7.10.8858) using the Zune trick (as was nodo and mango too)
Had problem with syncing though. I have lots of videos and zune kept giving me error C00D124D "Phone is not responding) while syncing some video files. so The upgrade process keeps failing.
Finally got it to work by reinstalling zune and clean up registry using WiseRC. Don't know actually what's wrong, because I never had this problem before. Anyway installing updates itself doesn't take long, but syncing and backing up take 1 hour. at least.
One of the update description says:
*Provides other Windows Quality improvement*
Does anybody knows what they are?
Hm... really happy now with the new look. Kind of having a breath of fresh air.

doconco says:

Anyone with AT&T Titan 2 got the update?
I can see people with different OEMs and carriers have received the update including other HTC and AT&T phones but not Titan 2.

I can 100% confirm that the Australian Vodafone HTC Trophy works with the trick! I have just finished updating to 7.8. Before which I was fully updated but note I had to download a total of FIVE updates each time using the trick before it finally got 7.8. Took about 150 disconnects from the net, but worth it in the end.

danielgr says:

Just want it to say I got it to work on my Japanese IS12T on AU-KDDI network.
Took me a bit of time, several trials, and 3 updates until I got to the last one, but I definitely love it.
Still, it'd be nice if Microsoft brought several other of the improvents that are completely unrelated with HW, such as the emoticons, from WP8. Guess I'll have to wait for my 2year contract to end and then update to WP8. Hope that by then it will have been launched in Japan, 'cause still no signs of it anywhere. We are definitely 2nd class citizens now as far as Microsoft stuff goes.

noshiro21 says:

please reply to post......going crazy here, i keep getting that my phone is up to date 7.10(7720).....

This actually worked, but because you have to do three updates, it took me several hours to complete all three updates. Now working like a charm!
I didn't have to put the phone into Airplane-mode, disconnecting the data connection and wifi was enough. Just follow this guide exactly to the words, and it will all work out fine for you aswell (eventually).

Not 1-2 seconds btw, more like 3-4!

coriodesign says:

Confirming the Dutch HTC Titan (unbranded): First I received the old update 8779, after that, I received nothing (it said no new updates), then I received a new update, with the camera button thingy, and after that I had to try a few more times (it kept saying no new updates) I finally received 7.8 :D

does your marketplace showing Bluetooth share and ringtone maker in Nokia collection?
I tried from link on the pages posted but can't download.
I have lumia 710 india

RobinPaul says:

i can't find them either :S

SwimSwim says:

Hey guys, here's a tip I picked up on in my experience of forcing the update: You pretty much have to get lucky. Zune seems to get finicky, it seems to connect so fast it tells you you're up to date, or it doesn't establish a connection before you dissconect and you get an error.
Just keep trying till you get it, change the timing a little, etc. It only took one try to get the preliminary update (No camera button required) update, yet it took me about 20 to get the actual 7.8 update. Just keep trying and hope you get lucky.

xchaser says:

I been trying to do the Cable Trick with no luck, I was able to do the cable trick for mango when it first came out. I think T-Mo USA hasn't updated the server with the wp 7.8 and that is why we haven't been able to Update.

Id like to know do you have disconnect the usb cable from the phone when closing internet connection.

Gopi R says:

No!! disconnect the Ethernet cable from the modem or disconnect the Wi-fi if u are using a laptop

aderud says:

Running 7.8 on unlocked Lumia 800 in Sweden (got a contract w 3). Used the forced trick and it works fine when you get your timing right!

Viperise152 says:

This method did not work for me on my AT&T Titan. I did get it to work using the cab sender method.

Gopi R says:

WOW!!!! the trick worked like a charm..tried 5 times, my third try was a success....its really true that the TIMING is third update is downloading while i type..YAAY!!!!!!
I am from chennai, India and I own a Lumia 710...

Greetings from Macedonia.
Kudos for the hack. After 10 unsuccessful attempts I finally managed to get the update! The thing that worked for me was:
1) turn airplane mode on
2) wait 5 seconds and switch wireless adapter  off.
Hope you find this useful.

Dell venue pro got update with this trick so dvp is also wp 7.8 device

gchandrujs says:

Thank you so much. This helped me a lot and by following this only i have updated my Samsung Omnia W I3850 with Windows Phone 7.8 !!!

codytrahan35 says:

still no luck today with focus att US, ive been searching for a rogers retail rom, but even on xda i only find links that lead to spam viruses and junk lol

doconco says:

Still no luck with ATT HTC Titan 2.
Can't believe much older HTC, Samsung and LG got the update.

Mike Fait says:

No older ATT though, right? I have ATT Focus, over 2 year old.

I have no clue how this works, but this did work for my lumia 900 AT&T....Awesome this method is :)
Nothing great about the update, but the resizeable icons are a real handy thing :)
Hoping for more useful updates in the future such as these :)

Yi Zhong says:

after 5 times tring it works to 8779, another 5 times to 8858. can't express how genius u r~!
8858 might be the last update for lumia 900, oh~ sad suddenly 

doconco says:

Fuck all of them, HTC, Microsoft and ATT.

codytrahan35 says:

its not microsoft, its att, i just did some research and found out att has been rejecting updates for older wp7 devices for quite some time. regardless of what they say the reasons are for, i read over quite a few, its probly cause they want new contracts and a chance to kick a few more people off that unlimited data(if they were lucky enough to grandfather in). at any rate im using the wph method on my focus since im pretty sure att wont push for the focus and it seems to be working pretty well so far.       if you want to go the same route

harshalsk says:

TMobile HD7 owners:  I updated mine using XDA Cab Method and works really great!
HTC and T-Mobile repeatedly said they do not have any plans to update.  So Screw Them.
Since this is the last update to WP7 I do not care. Cab method must be done in two steps as described in the XDA thread otherwise there may be some issues with settings sections.
Check the Cab method. My HD7 is carrier unlocked by T-Mobile (branded T-mobile)

codytrahan35 says:

just finished, and everythings beautiful and working, ATT focus 1.3 now on 7.8 thanks to jaxbot over at wph. for anyone skeptical about its ease its pretty much automatic and it works.

Mike Fait says:

I was only able to get one update loaded to my Focus on ATT. It is now at 8107. Can someone post the different firmware versions and what they mean? I believe I just got the disappearing keyboard fix, right? Thelast update eventually times out and then the phone says update was unsuccessful. How do you even tell what step you are on with the tool. The info goes by so fast?

Didac Palla says:

 I tried it and I did it. To the third step (8858) I needed trying a lot of times, 6 or 8 times more or less.
 Great Help, Thanks.
 I'm from Spain with a HTC Titan, free of operators

Pelatz says:

was not the day, or week.

After Trying 100 times i finally got my lumia 900 to update and when the update was done it was still on what do i do it keeps asking we to restore my phone...........

sadubon says:

Try this program it works perfect with my HTC RADAR of TMobile.

Sgt_Floyd says:

Okay guys, here's the trick, open zune, connect your phone and go to settings, start the default update check and note the number of seconds it takes to do so, after it is done checking, it will probably show "your phone is up to date." now what you need to do is start update check once again and disconnect your internet about 2 seconds before the average noted time, this will increase the probability of hitting the right time.
                                                                                                                                  other way to go is that if you are getting your phone up to date, then you are disconnecting later than required and if you are getting cannot check, than you are disconnecting earlier. 
                                        after a few tries it worked for me, on lumia 710, it installed 4 updates, the fourth one was nokia update for windows phone, i'm not sure what it does though..

saddam_bd says:

Working flawlessly on my HTC radar. Well it did take 3 hours of my time but finally came through. I did 3 updates all using this trick to finally update to win 7.8. I checked for how many seconds it took to check for update then subtracted a few seconds to pull out the lan cable. Internet is a bit slow here in Pakistan so it was usually taking 15 seconds on average to check so I pulled out the cable around 10 seconds to get it working.

Can't get my HTC T9295 to update...anyone with this phone had any luck?

It finally worked! You have to disconnect about 2-3 seconds after you check for update. You must count “1 telhas zebbi – 2 telhas zebbi” and NOT “Mississipi” in order for this to work. And finally, rest assured Nokia and WP…This will be the last phone I will buy from you as the update doesn’t have an Arabic keyboard. And I will not buy a new WP for that.

I have an HTC titan took me 2 tries put the phone an flight mode  and u have to disable it about 2 sec

Looks like ATT is not releasing the update for Titan 2

Pablopavi says:

Worked on my Nokia Lumia 800. Count to 5 before disconnect from the internet worked better for me.

Has anyone confirmed this in a Samsung Focus S from att?

worked for me after few tries, thank you

GuitarGuyJon says:

Still haven't gotten it.. Forcing it won't work for me either. I really hope they don't forget about me..

JimboJV says:

Thanks, my lumia 800 is now updating to wp7.8
I had to download two minor updates before the 7.8 update came through.

darth3pio says:

Thankfully I didn't need to force it like I did with Tango, my HTC Titan international carrier unlocked import just got the 7.8 update.

Squadromeo says:

Just updated my wifes HTC Radar (International Unlocked). Had to use the trick discribed in this article though. Total updates installed were 3, of which the last one was the 7.8 update. Sweet!

minep says:

What has 80072FA8 error or just no update found!
On this time I tried a long time update with disconnect trick. But... no updates.
NOW... from FIRST time update was found!

yeah... first of all good things happen to UK. So we will use UK proxy.
Go to Settings - mobile network , then edit apn. In "APN, Username, Password" I typed my provider settings. In "Proxy server/URL" type and in "Proxy port" type 8080. Here Done.
Next step: in computer STILL connected internet, in phone wifi is disconnected.
And last step: in Zune click update. Waiting about ~2 minutes, because proxy is very slow.

iqbalsn says:

HTC Radar, unlocked, tried this trick for about half an hour, got all 3 updates. Thanks for sharing :)

Darkness690 says:

I'm still unable to get the update for my Lumia 900 on AT&T. I was getting an error, but no longer am after uninstalling my Anti-virus/firewall. Now Zune is just saying my phone is already up to date (8779) and this trick isn't working.

LeeMasta says:

Are you able to force the update on the Samsung Omnia 7 locked to T-Mobile in the UK?

djdoubt03 says:

Just incase HTC Twitter user being dumb any   US AT&T Titan II users able to update?

doconco says:

No, I tried 1000 times, this method doesn't work on AT&T Titan 2.
I have updated it using seveneighter, everything works ok except some of the settings for example lock+wallpaper, about, etc... do not open.

petrkratina says:

Works like a charm on my HTC 7 Trophy! Thx guys!

dubie v2 says:

If I do this, and then the update comes for my HTC Radar 4G for T-Mobile later with Zune, what will happen??? 

works on optimus7 romania. sync between update and disable network is everything.

As a recently disgruntled AT&T  HTC Titan II owner getting tired of HTC refusing to pust updates I used the Seveneighter app to do the update, works great.

Just did my Lumia 800 (Unlocked from NZ) with  T-MO SIM here in to good old US!..

metodscaeft says:

Worked fine for me. Got it first time round, then as it wasn't upto the final build had to do three times. Only took an hour altogether. Lumia 710 - unlocked in UK.

We have found a  way to install Windows Phone 8 OS on to single core phones by our university researches. We implemented this on Lumia 710 and 800 series. But we have to disable some feature on WP8 which provides good sync. between threads and processes on real WP8 phones. However, we made it. We are testing the phones for 4 days, and we never been crashed. 
We can never use dual core advantages but, by switching between processes so fast provides us a dual-core-like environment. (This slows down our application nearly %10 because of context switchings between processes, but cheats OS to think it is processing on a dual core processes.) Nevertheless, we can use the OS fully functional with applications and everything.
We will update you how to do that, pray for us not to things go bad.

vish123 says:

i did the update thing forced it and it came on ma phone sayin the update is available then i did it and nthing seems to change i check on the about area in settings and it came software version 7.5 after it said update successfull

Yamishi says:

Question for any savvy people out there:
I've got an AT&T Focus Flash that I've got running here in Canada on Rogers. I used the Samsung wireless manager app to make it run on Rogers. However, do I still have to wait for AT&T to enable the update? Rogers does not carry the Focus Flash. Will I have to reset the settings to connect to AT&T's network, or can I just leave it connected to Rogers and hope the update comes?

matthoms says:

I have a Focus Flash as well. I can't answer your question because I don't know. But, I do know that I have tried force updating my phone several times and it doesn't work. I don't think our phone is popular enough to get the update. I know the Lumia 710 won't be getting the update but that might also be because it is a T-Moblie phone. Anyways, I have yet to get the update and I'm assuming two things: we won't be getting the update or it's because our phone isn't well known enough to get the update.

noshiro21 says:

im soooo tired of trying everything, trying to get zune to pick up the update!!! disconnecting is really not letting the update go thru....keep saying is up to date, 2210. 
i dont know what to do anymore...i downloaded sevenneigher, but dont know what to do with it? no instructions or the exe. icon!!

SalmanNaseer says:

I updated from Windows Phone 7.5 yo Windows Phone 7.8 and it's awesome! My Lumia 800 is totally changed!  If anyone is having a problem in the update process, you the following method:

percychow says:

FWIW - the easiest way to get the update is to fire up the Windows Phone app on your PC or Mac. Hit the "Check for Updates" button in the program with your Lumia plugged in. The WinPhone app will download the update pretty fast onto your PC and then update/install the Lumia. 

I did this on a Friday night and the update/install was done in less than an hour.
Hope this helps someone out!

asna_n800 says:

I'm just getting error code 80072FA8 whenever I press update on Zune. Its really frustrating as i can browse websites as well download contents, but Zune keeps on telling that "Can't check for updates right now. Please try again later"
While starting up of Zune, it displays "Can't connect to internet through your phone". Are they both relaated somehow? 

minep says:

What has 80072FA8 error or just no update found!
On this time I tried a long time update with disconnect trick. But... no updates.
NOW... from FIRST time update was found!

yeah... first of all good things happen to UK. So we will use UK proxy.
Go to Settings - mobile network , then edit apn. In "APN, Username, Password" I typed my provider settings. In "Proxy server/URL" type and in "Proxy port" type 8080. Here Done.

And last step: in Zune click update. Waiting about ~2 minutes, because proxy is very slow.

TopGunnah1 says:

hey can you explan more on what u did.

minep says:

It's no clear still? :) 
Zune check updates over phone internet. We know, that Microsoft gives updates just for some region firstly. Basic regions are UK, Germany, Spain, France... (I'm from Lithuania) I read, that someone got update without tricks in UK. So, I find working proxy from UK. Then I edited APN in phone, that he using to cellular data internet over proxy. And last ... Zune check for updates over phone internet (now he thinks, that phone is in UK). And... update is available. :)
Hm... I checked and is possible add proxy over wifi:
Go to wifi settings --- long press on your wifi network --- enable Proxy --- add IP and Port.

TopGunnah1 says:

oh ok i understand thx :)

TopGunnah1 says:

hey what did u type for APN, User name, and password

minep says:

My carrier settings (you can find that in your carrier web page).

TopGunnah1 says:

i found and did everything u said but it still says im up to date 

minep says:

How much times you tried? Maybe your phone is with carrier software? My is open.

TopGunnah1 says:

i tried 7 times im with at&t :(

asna_n800 says:

Well today I kept my wi-fi on phone enabled. And tried to forced update, like 10,000th time and yep, an update was available. But in installing it gave another error, aaargh. So, after again working like a maniac for 6-7 hours, I'm able to find an update. Hopefully, this time it works!!

I have tried several for my Omnia W in India but i am not getting any message :(

finally managed to get the 8779

Works perfectly with my Nokia Lumia 610! On my experience, I had to update it thrice.
I disconnected each at around 15 seconds and it worked.

Anaba says:

It wont work for me. I have a Lumia 900, and it just keeps telling me it cant check for updates at this time when I try this trick

jbjtkbw00#AC says:

It was telling me the same thing. Then, I found I was disconnecting too fast. I had to count to 3-4 and finally, it was beginning to work. So, if you're getting that message, that's what that means. You're disconnecting from the 'net too soon.

sudarsanyes says:

Worked wonder - Nokia Lumia 710.

I need to try this with my Lumia 710, im disappointed in Tmobile for this bad call

UK Users!

I collated some info from the comments here and elsewhere after following the above instructions with no success.
This worked for me:
Plug in. Load zune. Phone. Settings. Update. Status: no update available.
Airplane mode. Update. Pull ethernet cable after 5 seconds. Status: update available.
Reconnect ethernet cable. Update.
Rinse and repeat until you reach 7.10.8858.136.

Hallelujah..!!! I just updated my Lumia 800 (Indian bought and unlocked) to WP7.8. This method works perfectly with a few minor adjustments that i had to do after nothing seemed to work. Finally after reading all the comments and a few experiments later (and the 100s of times i tried this method unsuccessful before) I managed to successfully upgrade. The key here i feel is determining how fast your net connection is.
1. After you connect your device to Zune you need to determine exactly how long it takes to get a response from the servers
2. See how long it takes to get the following response "Your phone is up to date".
3. Once you get done with timing how long it takes (i used a stopwatch to be precise as thats how desperate I was) you need to play around with disconnecting your internet connection a tad before that number. It turned out that I had to wait 5.5 seconds before i disconnected as I got the "your phone is up to date" message in around 6 seconds.
4. Keep trying (trust me it works as I initially thought that my device was not lucky enough for the update) and you will have to repeat the same steps till you work up to the 8858 update.
Hope this helps. Cheers!!
