Seems as though everything is back on after we mentioned the patch Samsung released yesturday for their Omnia 7, which addressed the issue with devices not being able to update. Microsoft have confirmed in a blog post that the Samsung Omnia 7 handsets will begin receiving either NoDo or 7392 (dependant on whichever stage you're at) in stages, but unfortunately no word has been said on the Focus.
If you haven't recevied any error on your Omnia 7 with updating to 7392 from NoDo (code: 801812C1) then you will not need to use the Samsung patch, just update as you usually would via Zune or Windows Phone 7 Connector. So, fantastic news all around, right? We'll keep you all up-to-date with anything we receive for Focus handsets.
