Ok I had this problem, and I had this today with my 3rd Lumia that I was sending back, I wanted to reset to delete everything. It goes to spinning cogs and stays there for an hour, I do the volume up then down and then camera and power button and it restarts and went to cogs again and then went past that spinning cycle, so u don't need to flash it!!! This is a much easier way, just keep trying, I did it 3 or 4 times before it worked,
I did the volume down/power reset during the gears and thats when I think it officially bricked. Wish I would have known about the other combination.
This is pretty consistent. I just use the vol down+power to get it to reboot and fire up the gears again. Took about 5 minutes maybe on the second pass.
unfortunetly its a common issue it seems. Mine is bricked too, I'm waiting on a replacement unit right now as I don't want to void my warranty and can use my HTC Titan again... the Lumia 800 a nasty issue that would not allow the phone to wake up when battery was finished. I don't even know why the reset on my L920 takes this long...on other phones (Android etc.) it takes like a minute. For whatever reason on WP8 hard reset takes long and in the case of Lumia 920....can get stuck for whatever reason.I've been wanting to reset my phone to sign in with a new account, but am so hesitant because of all of these reports of the phone bricking like this. Is this problem really all that common? I'm terrified of this happening haha.
ok, so if i flash back from Portico to old software on Nokia lumia 920 att, how does that void my warranty? Because my battery is ****. Cant i just upgrade to the latest firmware before i send it back? I dont see how that could be an issue. On my jailbroken iphone all i did was update before i sent it to apple and no problem. How is Nokia different from apple in this sense?
I had bad battery life before and after portico. I did hard reset after being on Portico five days and manually flashed latest update, which I assume is Portico, and have had excellent battery life ever since. Might try it before you flash old version. It is the only thing that has helped my battery life.
