Before Nokia cut access to its servers Nokia users could download software updates that weren’t due for months, this however was changed earlier this year, but users still force certain updates using Nokia’s updating software.
Earlier today Nokia pushed the GDR2 update for Lumias on their servers which meant we could actually download and flash the update easily.
and today it happened you can flash your Lumia 920 right now using this app which as it turns out the easiest one yet
back up your apps and contacts run the Nokia software updater follow the course of the app
if the update available is named 3047.0000.1326.2002
then this is Amber; or GDR2 and you should able to download and install it.
“this is a clean update so beware. 🙂
as always please understand that flashing your phone even through Nokia software can void your warranty.
