Hi,
I just bought a lumia 920 branded ATT from USA, i live in France so i try to put a different rom on it.
So i've tried to use NCS to replace the current rom RM-820 to a new one that i've downloaded : a french RM-821,
but that doesn't work and i don't know why : when i'm in ncs, it's show me the current version of the lumia, but in "new software version"
that tells me not available while i've put my rm-821 rom in a folder rm-820 in products folder.
Can someone help me ?
it is possible to do the switch between ATT rm-820 to RM-821 fr? if not, can i put an unbranded rm-820 rom at least?
Thanks a lot in advance (and sorry for my poor English)
can someone help me please ? :'(
debranded
It's ok, i did it, i debranded it!!!
Now i need to unlock it from at&t.
But i have another question, I have another lumia 920 at&t which is unlocked, if i debrand it too, will it still unlocked ?
Thanks in adavance

it'll be unlocked no matter what firmware you install. I had locked AT&T and after unlock I tried different roms, but be careful when updating from RM-820 to 821 if you update rogers pre-portico via OTA to portico you won't be able to return to RM-820 anymore see there are many threads here about the steps.
Thanks ok so i will flash it too,
But i don't understand why someone would return
from rm-821 to rm-820, there is any disavantage to have the rm-821?

Hello, I have a Nokia Lumia 920 of AT&T and I wonder if I can install a firmware RM-821 europe.
thanks in advance
Why would you do that?
But it will probably not work since the LTE frequencies in the US are other than those in Europe: http://en.wikipedia.org/wiki/List_of_LTE_networks
then do not install any European firmware. Thank you very much friend

Yes you can do it but not all of the RM-821 have the 4G enabled. You may have a look here at the new post created:

Hi Ellokomen.
Probably a stupid question, but what are the advantages of a developer ROM?
The Developer ROM has been there since at least November (as that's when I downloaded it)...
I don't know how significant it is, but there was never a Portico version of the Developer ROM before they were all pulled so it doesn't appear it's first on the list for updates if that is what you were thinking.

The portico version of the developer ROM is now available (see 1232.5951.1249.1002 - RM-821 VAR EURO1 Developer Device).
But again: what would be the advantage of flashing that to my phone?!?
Can the Developer rom side load apps?

I think it would help to remove the internet sharing block on AT&T and rogers phones.
Has anyone tried to flash this RM-821 ROM onto a RM-820 device? I know that technically they are different phones but you could flash the RM-819 (Lumia 800) onto a RM-801 without issue aside from perhaps a missing 3G band. But the 820/821 have exactly the same 3G bands just different LTE (which I don't care about) so it shouldn't be an issue right?

I flashed this rom on my att lumia and everything seems to work fine. Only thing is I can't tell if my LTE isn't working tho b/c I don't live in an LTE market.

That's odd because when I tried to flash the RM-820 ATT Firmware to my international RM-821 Lumia Nokia Care Suite said that it's for a different model (or sthg like that) and then aborted the flashing process. This left my phone "soft bricked" - meaning that I had to re-flash it with a RM-821 ROM to get it working again.
I wonder if this Dev ROM might actually be a RM-820 ROM that is only (by mistake) labeled as RM-821?????
Has anyone tried to flash it to a RM-821 international model yet? Because from what I know the only Dev phones were RM-820 models and that always left me wondering why there is a Dev ROM for RM-821 but non for RM-820 when on the other hand there are only RM-820 Dev phones but no RM-821 dev phones.

It's not mistakenly mislabeled b/c nokia care suite now identifies my att lumia as a RM-821 (originally RM-820) and now in extras+info the manufacturer model name is RM-821_eu_euro1_425 so it's obviously designed as a european rom.

Well this makes me wonder whether RM-820 and RM-821 might actually be the exact same phone hardware wise with only some (artificial) lock preventing cross-flashing between those variants ...
Would be interesting whether you could flash other non-developer RM-821 ROMs to your RM-820 now and also if you could still flash it back to an RM-820 AT&T or Rogers ROM.
product id incorrect

Did you try it using the latest version of Nokia Care Suite?
@patrick92260
Which product code does Nokia Care Suite show for your phone now? The original AT&T one or the one for the RM-821 Developer ROM?

It shows the product code for the RM-821 dev rom and identifies it as RM-821.
edit: looked at the wrong place for the product code. It still has the original ATT product code but NCS still identifies it as an rm-821
I just tried to flash my att Lumia several times but just get the phone bricked and flashed back to att rom
Sent from my RM-820_nam_att_100 using Board Express
Oddly the update menu entry is grayed out for me too but you can download a later version here:
http://www.seidea.com/2013/01/03/nokia-care-suite-pst-5-0-2012-51-4-4/
(don't forget to uninstall the old version before installing the new one!)
What @patrick92260 said about his phone now being identified as RM-821 and even with the Developer phone's product code makes it seem like he did not only flash the phone to a different ROM (with keeping the phone's original identity [model, product code] intact) but he also somehow managed to overwrite the part that holds those "phone identity information" with the ones of the Dev phone.
Maybe this has sthg to do with the version of NCS being used:
-the old version just flashed the ROM but didn't touch the "phone identity information", it allowed to flash to a different product code but refused to flash to a different model (RM-821/RM-820) and even after flashing to a different product code the phone still had it's original product code
-now the new version on the other hand might not only flash the ROM but might also overwrite the "phone identity information" with the ones of the ROM you are flashing and is thereby effectively changing the phones "identity" (model, product code) to the one of the ROM you're flashing.
This is just a theory of mine but when summing up the facts that:
-a few weeks ago I was unable to flash my RM-821 to an AT&T Portico ROM and now @alfaro58 tried it the other way round (flashing his RM-820 with an RM-821 ROM) and we both ended up "soft bricking" our phones and had to re-flash them with the "correct" model's firmware to un-brick them
-a few months ago sb tried to unbrand his Roges RM-820 by flashing an RM-821 ROM and he also ended up soft-bricking it and then had to wait for a few days until a RM-820 ROM became available on Navifirm before he could unbrick his phone by flashing one of those
[email protected] now basically did the same thing that other guy did a a few months ago (flashing an RM-820 with an RM-821 ROM) but instead of soft-bricking his phone it seems that he even managed to not only flash it with an RM-821 ROM but to actually make it an RM-821 phone.
All these facts kinda lead me to that assumption that it might have sthg to do with that new Nokia Care Suite version that was released earlier this month.
If I still had that buggy pre-Portico ROM on my Lumia I wouldn't hesitate trying to flash my RM-821 to a Rogers or AT&T ROM (because those seem to be first in line when it comes to updates - or at least they were this time) but with my phone now working perfectly with that RM-821 Entel ROM and me having several exams during the next few days I'm really not going to wipe my perfectly working phone just to prove this theory right or wrong - I hope you understand that.
@patrick92260 Which version of Nokia Care Suite did you use?
@alfaro58 Maybe you want to install the new NCS version and then try to flash your phone with the RM-821 firmware again using that updated NCS version?
Hey,
i´m new on Nokia ROMs. I already downloaded NaviFirm and flashed the RAW_DEVELOPER_ROM - everything works fine...
Can somebody explain me the structure (name) of a ROM?
Thanks in advance for your help!
SP
wanna know this too
Bumping this. i would love to know this too.. any WP8 Gurus out there??
I am purely guessing it is a Branded Everything Everywhere ROM, CV is carrier vendor, RM821 is the device code for EU models?
Lumia 920 has four device codes, RM820, 821, 822, 867 the latter being the chinese 920T,
EE_CV is for Everything Everywhere branded rom.
If you are looking for UK then it will be GB_CV

Hi, yes I want to flash that ROM because I'm trying to enable AWS band on my 920 (RM-821). I've been reading a lot about this, and not many people have tried this process, but i read that flashing a specific rom that uses the 1700-2100 band (RM-820) you can then enable AWS on an RM-821. the problem most people had is that they dont know wich ROM have LTE AWS enabled. I found an article on a Perubian online newspaper where the goverment said that the lumia models being sell there were compatible with the AWS LTE band. So i want to try it.
thx for the answer, any idea of when will it work again?

You *may* get a FFU signature error, that prevent you to flash this RM-820 ROM on your RM-821 Lumia device. If you will not get a FFU signature error and that the flash of this RM-820 ROM on your RM-821 Lumia device works, it *may* that your RM-821 Lumia device loses some networks bands.

For those who are interested, here is what I did to my AT&T Lumia 920:
start off with a Portico AT&T ROM (OTA-updated a few weeks ago on the still locked phone)
remove SIM unlock with AT&T provided unlock code
flash pre-Portico Rogers ROM
OTA-update to Portico Rogers ROM
flash Portico EURO1 DEV ROM (RM-821!)
flash Portico Rogers ROM
flash Portico LTA1 MX ROM
flash Portico GLOBAL BLACK SWAP ROM (RM-821!) ---> saw H, H+ indicator after this!!!
flash Portico Rogers ROM ---> 4G indicator
While flashing the LTA1 MX ROM (the Latin America ROMs are nicely debranded RM-820 ROMs but don't support LTE, at least in their cellular settings for highest connection speed), I decided for whatever reason to just give another RM-821 ROM a try and went for the GLOBAL BLACK SWAP. Maybe flashing EURO1 DEV again would have also done the trick as well and just flashing back and forth somehow enabled AWS. I don't know exactly what caused it but I am happy AWS works on the AT&T Lumia 920. This phone now certainly is the Überphone
and here the one with the product codes
Flash to Pre-Portico Rogers ROM: RM820_059Q6W4_1232.2109.1242.1002_039
OTA Update to Rogers ROM (1308)
Flash to European Developer ROM: RM821_059R4H6_1232.5957.1308.0002_027
Flash to Rogers ROM: RM820_059Q6W4_1232.5962.1314.0000_156
Flash to Global Black Swap ROM: RM821_059Q5C6_1232.5951.1249.1004_044 (No H/H+ as claimed by others, LTE disappeared from network options)
Flash to Rogers ROM: RM820_059Q6W4_1232.5962.1314.0000_156
