ive had my L920 go into "GoD" mode...it just took multiple resets (while stuck in Gears) to eventually continue to bootup process. The last time i did this i took 4 attempts. I waited 40 mins, if it didnt boot up by then i would VolumeDown + Power, continue this until it moved on.
I've tried everything...even tried that firmware update but it stopped because I couldn't connect to the Nokia servers...I let it go all night last night...woke up to gears...I've tried multiple ways of pressing buttons to reset...gears keep a turning.
I am getting a replacement in the mail but my workplace said they would pay my early termination fee and use a brand new, Lumia 928 we got from our Verizon rep and they take over my phone bill. Even though I'll lose my unlimited data on my number, I'll have unlimited data on my work phone and I plan on being here for a good while and by the time I may move on, I can afford any data overages I may get if I get my phone again with metered data.
So when the replacement arrives, I'll send my defective Lumia 920 back and then give it to my wife who cracked her screen on her red 920. Saves $150 on replacing her screen!
She is OK not having red.
