Nokia and Microsoft are slowly (but surely) looking to roll the GDR2 + Amber update out to consumers with a Lumia Windows Phone. Those with a Lumia 928 and who are anxious to get the update will be able to get dirty by manually applying it to their device. Windows Phone Central member tungha has published some links on the forum that contain files for the Nokia Amber update.
Fancy some flashing? You can now update your Lumia 928 manually, should you know what you're doing of course.
Just like the update published for the Lumia 920 and Lumia 820, the files can be downloaded and flashed directly to the Lumia 928. This brings its own problems since this will mean the device will be wiped and all data lost. This is why we'd never recommend anyone to go down this route, unless you truly know what you're messing with and aren't bothered about losing saved games and app settings.
Should you require reminding, Windows Phone 10327 (GDR2) is a minor OS update that brings FM radio, some enhancements to Xbox Music, WAV file playback for voicemail, fixed Other storage, and other minor bug fixes in addition to enabling the new hardware found in the Lumia 1020.
Nokia’s bundled Amber update, which is what is causing the delays for release, allows the new Glance screen, flip to silence, Lumia Color Profile and an improved camera experience, making the combo of an update quite interesting for consumers.
If you're not prepared to go down the manual update route, fear not as mobile operators are expected to roll out this rather important update this month. Head on over to our community forum for more details, some instructions on flashing through Nokia's Care Suite and the general discussion. Screenshots via Imgur, thanks to Trevor for the tip!
