Generic Firmware For lumia 920

[louthefirst]

Sorry if im being stupid here,

I have a EE Lumia 920 (unlocked) in black and I would like to know can I change this to the developer firmware (like the firmware from the original Rogers delivery unbranded or a newer version it),

The main reason I would like to do this is to enable the 1700MHz AWS and I really would like NO Branding.

I Have NaviFirm Plus but I can't work out which is the right firmware.
Does anyone know if this is possible, hot to do it and if so which firmware should I use.

Sorry if this has been talked about before but the only references to it I can find are very confusing and don't refer to changing a European Lumia to a global version.

Thanks in advance for any help.

You can definitely flash it with a Generic f/w - just not that for Rogers?AT&T's because it's a different model. Your's is RM-821...

There's a developer f/w for the RM-821 in Navifirm, 059R486 (1308.2). I personally haven't tested it but it's definitely for the RM-821 model. Proceed at your own risk. :wink:

I'm using the Finland version (1308.1)
