I bought a nokia lumia 920 from AT@T, i unlocked it and now I want to flash another firmware. I already downloaded 3 or 4 different firmware and it says that this product wasn't meant for this device. I wonder is the att lumia 920 only made for att? Cause somewhere here i read "non upgradeable"...does anybody know anything about it? Thanx

my mobile also never bricked when i changed my firmware,,
my lumia journey so far,,\
( im living sri lanka)
*bought from ebay (at&t)
*called at&t got unlocked code use it here
*flash to rogers
*updated latest (rogers) via phone,,
*then flash to euro1 FW
remember when you flashing don't connect the phone untill nokia care suite say press volumbe down button and power button
another thing before you do the flashing do factory reset,,

Thank you, vimukthi999. But I wait for the retry option appears and one or two questions. I have press volume down and power button untill it vibrates and then plug the cable and keep volume up pressed untill i see the other nokia logo or should I plug the cable and then volume down and power and then volume up?

this is exactly how i did it,
so now you try to your firmware with out connecting your phone off when you get the message from NCS retry ,,before you connect it again to computer turnd off then holding volume down and power on button (lock button)same time as u holding buttons try to connect it back to computer,,
in my case i asked to friend hit retry button on the compter while im holding two button and connecting it to computer,,
when you feel viba still hold volume down button will work,,

Thank you, my friend! But I give up on it for now!! I just tried what you said, i've read a lot of forums and nothing works. It always says that the firmware i'm trying to install is not for my device. What product code did you use to change the firmware and i can install rm-821 on a att@t rm-820, can't i? Cause I tried both and no good answer!! :(

this is the code for dev rom 059R4H6
dev rom rm-821 i have now,,yes it can
exactly whats the version of fw you trying flash with?
whats your current at&t version,,?
did you reset your phone before flash?
u said its unlocked did you put another sim card non at&t?
