As far as I know, the Nokia Software Updater for Retail, wipes the phone clean and installs the update. So that would work don't you think? I just don't want to loose my warranty that's all lol
Re: How to update any L920 to GDR2/Amber in 13 easy steps!
Where do you get nokia software updater for retail? I might try it. The way I see it though, both of these methods flash the phone, and something with at&t's ROM doesn't allow it to be flashed back from another ROM. I don't see why that world work over NCS.

I'm really tempted to do this.
I am tired of waiting for AT&T to release an update with missing features anyway.

This is what Nokia Software Updater shows when you connect an AT&T 920 updated with the Amber rm-821
It still shows warranty and the original product code wich in my case is a black AT&T Lumia 920
The type is showing rm-821 that's why it shows the error cause product code and type doesn't match and that's why Nokia Care Suite doesn't recognize the device when trying to revert back to AT&T.
There has to be a way to do it manually with Care Suite. This is only software. Everything is suppose to be the same on the phone. Maybe flashing the phone again with rm-821 but nenaming the files to rm-820 before the flash. I don't know. I don't have a spare phone to experiment.

Ugh, Nokia care suit/Product support tool detects rm-820 (rogers), but doesn't detect rm-821. Both of them are in the Products part of the folder. I have tried deleting and re-installing and stuff but it just doesn't detect it. What am I supposed to do

also, remember that you have to open product "RM-821" for it to recognize the French rom.

yeah, I extracted both in the products page, it recognizes rm-820 and show that its rogers. but doesn't show rm-821 to be present in the Products Support Tool. What do you mean by open? I mean I opened both the folders. RM-821 is still not showing up..

Re: How to update any L920 to GDR2/Amber in 13 easy steps!
Am I missing something? I click "update list" and nothing happens. I have no choice to select the Rogers ROM or click start.

you have to click file, then open product, then type in rm-821. It should show a red Lumia.
Re: How to update any L920 to GDR2/Amber in 13 easy steps!
can you post a screen shot of your products folder in file explorer please?

Re: How to update any L920 to GDR2/Amber in 13 easy steps!
I've read through the entire thread but things have gotten very confusing over the last 4 or 5 pages. I have an AT&T L920 and I'm familiar with the flashing process but I just have a few comments:
1) I have downloaded the French Amber rom (RETAIL_eu_france_267) and the Euro Dev rom (RETAIL_eu_euro1_425). It is my understanding that both are Amber roms but the French rom is technically a global French rom and not a global English rom. It is also my understanding that the Euro Dev rom has all LTE bands unlocked and displays "L" instead of "4G".
Advantage: Euro Dev rom.
2) @juan6996, you first flashed using the Euro Dev rom in the beginning and you posted that you were able to sign-in with your MS ID and restore a backup using the Euro Dev rom. You then flashed the French rom and could not restore a backup due to wifi not being available in the beginning. It is my understanding that if I install the Euro Dev rom without installing the French rom, I will be able to restore a backup. I do not want to install everything manually as I have 6 email accounts, a crapload of sms and tons of apps!
Advantage: Euro Dev rom.
3) Tethering seems to be an issue. I have a AT&T mobile share plan which automatically includes tethering. I use this for my Surface RT and is a necessity. The majority have had success using the French rom and keyboard trick but has anyone successfully been able to tether using the Euro Dev rom?
Advantage: So far it's the French rom unless stated otherwise.
I think it's safe to assume that the Amber Euro Dev rom seems like the best rom to stick with unless tethering can not work.
juan6996 and everyone in this thread, thank you very much for all your efforts and experiences.

Re: How to update any L920 to GDR2/Amber in 13 easy steps!
Thanks for the guide! works perfectly I am using my NL920 unlocked on T-Mobile without any issues. The new Nokia camera app is really impressive... The only tip I would add to your guide is to install the Nokia PC Suite because it will install the USB drivers that were missing after flashing the rm-820 file. Otherwise thanks a lot!

Can I start from step 9 if my phone already is RM-821?
