I'm currently using Rogers Lumia 900 (RM-808). I would like to update the firmware to RM-823 so that I can have a non-Rogers firmware. Is it possible to change the product code at all?
Or is it better for me to flash a ATT firmware instead>?
As far as I know, there are a few people trying to do this but nobody has successfully flashed the phone.. They've been able to trick the flashing software into interpreting the RM-823 ROM as an upgrade to their RM-808 phone, but once the flashing process begins it stops around 5% and the phone reboots apparently with no changes...
I'm pretty sure that you won't be able to flash the AT&T firmware..I have an AT&T phone, it is also RM-808, so even if it were possible to flash to the AT&T firmware I don't see how it would help you.
hi
been a long time user of the xda forums and love the site thanks to all u who keep it up and running :good:
so i got me the lumia 900 a couple of weeks ago and started waitimg for the upcoming 7.8 update but i`m not the most patiend guy around so
when finally the 7.8 leak came out i figured why the hell not try to get it to my phone
never flashed a windows phone before so had to do some reading to figure out how to do it
and it seems quite hard to find any deasent information anywhere or everything i splattered around on different sites
so i thought i`d make a little guide here to all of you because it was rather easy after you got all you need.
so here we go:
1.download navifirm+
http://www.softpedia.com/get/Mobile-Phone-Tools/Nokia/NaviFirm-Plus.shtml
2.download nokia care suite 5.0
http://www.nokiabreak.com/download-nokia-care-suite.html
3. install navifirm+
4. download the correct package your lumia rm-808 or rm 823
the latest firmware is the one that is the last the list... (your RM is written on the box your phone came with)
im from finland so mine is RM-823 Country Variant WHITE
5.install nokia care suite
after installation also install the drivers that are in the nokia installation folder
6. unhide all your folders
7. go to c:\\programdata\nokiapackages\ CREATE A FOLDER NAMED Products
8. cut the package you donloaded via navifirm and paste it in c:\\programdata\nokiapackages\Products
and rename it to your RM
In my case it looked like this when finished c:\\programdata\nokiapackages\Products\RM-823
9. now run nokia care suite AS ADMINISTRATOR and choose Product support tool for for store
10. connect your phone
11. chose programming and refurbish
12. if you`ve done everything right it should give you the code for the old version and the new version
13. press start and just wait til it`s done flashing should take about 5-10 minutes til it`s done
this worked just fine for me, no problems so far and everythings running great in 7.8
i
Windows phone 7.8 Argentina Personal
I tried it yesterday and it works perfectly.
In case, here a link with a slightly more detailed tutorial::fingers-crossed:

Not yet, you have to wait for RM-808 from AT&T
For Lumia 900 AT&T owner..the reason why u can't just used the variant that we all can used is bcoz ur Lumia is different from any of us..remember that AT&T Lumia have an LTE connection which mean different driver, software, etc. So you guys have to wait whether AT&T itself or Nokia to make ur variants, as i can see, theres no other way
Gotcha, thanks. Well here's hoping that the AT&T version of 7.8 is released soon.

hi
i have a movistar 7.5 lumia 900, and i want to update to 7.8, but: there is no update for my product code and my phone is already sim unlocked but i received it that way, so i don't have the unlock code, is there a way to update without sim locking it, or is there any sector or part that i can backup to restore the sim unlock, or is there a product code or flashing way as well that will not lock it, cause i us another carrier and even if, the update for my product code comes, i'm afraid it will lock after updating it?
any help, guide or advice
thank you very much indeed

hye there, 1. u dont have to care much about the product code, theres no big different between variant, only carrier logo, app..basically all variant just the same, my phone is Singapore set, a small country, yet i am flashing Finland variant and everything works just fine as of now.
2. As for sim lock/unlocked, as far as i know, only AT&T Lumia is sim lock and can be unlcoked already by calling AT&T if not mistaken, and no, i dont think u will be sim lock after updating, an unlocked set will stay as unlocked just my 2 cent.
Note: i've already flash 3 different variant on my Lumia 900, Sweden, India and lastly Finland, no sim lock or whatsoever, all 3 variant, my sim card just working fine, can sms, call, online and all. The diffrent is logo when u startup your phone, and language on first install (Ex: if u choose sweden variant, on first start there will be sweden language, but u can change it on next screen. be careful not to bricked your Lumia while flashing xD

i dont think you can flash anything to AT&T Lumia yet, the bootloader prevent you to do that.
Hello Guys, Do you know anything about this?:
I tried to flash the fimware rm-808 MEXICO LTE COUNTRY VARIANT (12310), but i cant, ALWAYS SHOW ERROR o said OSBL reported an error, I only can flash THE SAME FIRMWARE (AT&T BLACK)
Tnx!!

are you trying to flash WP 7.8 on that AT&T phone? if yes, the answer is you can't do that. Variant for RM-808 is not out yet. If you are trying to flash an older update, the answer might be you have an locked bootloader.
edit: obsl = operating system bootloader, so you may likely had an locked bootloader.

OOO, thanks!, and i tried to flash 7.5 version of MEXICO COUNTRY VARIANT because it is debranded and have TETHERING! U_U
did you use "recovery" in 'nokia product support tool for Store 5.0'? I used this to put the mexican variant onto my rm-808 and i have been really happy. I have a rogers version though, don't know what different in the att one

If you have an unlocked att lumia 900 does that mean your bootloader is also unlocked or is it independent? I have the telcel rom downloaded and ready to flash just wanted to ask as i need my tethering and mms!

If you mean unlocked, as you entered in a 7 or 8 digit (I forget which) number, then no. Your bootloader is still locked, and that'll do nothing. What I'm saying is, you're trying to put a square peg in a round hole.
hello I'm trying to flash the rm-808 telcel varian on cyan rm-808 att nokia lumia, because the telcel variant no have operator customization, making the Internet sharing works without having an account at att-mywirless, and this variant of telcel is also LTE
Theoretically the devices are the same, but I could not successfully flash the att lumia with it, but people with the rogers lumia can flash the telcel variant without problem and enjoy a more original rom.
maybe in this thread between all could try to find a way to flash the telcel rom it is also rm-808
what I am doing is to download the telcel firmware from navifirm, once downloaded, rename the 3 files containing the product code with the code variant of my cyan att lumia
1. RM808_059Q7C4_2175.2302.8779.12310_002.dcp rename it with RM808_059M7R4_2175.2302.8779.12310_002.dcp
2. RM808_059Q7C4_2175.2302.8779.12310_002.vpl rename it with RM808_059M7R4_2175.2302.8779.12310_002.vpl
3. RM808_059Q7C4_2175.2302.8779.12310_002_signature.bin rename it with RM808_059M7R4_2175.2302.8779.12310_002_signature.bin
then I go to the folder C:\ProgramData\Noki\Packages\Products and created a folder called RM-808 and copy all the files to it
next I run the program product support tool for store and connect my att nokia lumia 900 cyan, in the Connection column select "no connections" next in the menu go to open product and select RM-808
nex in the programming tab click on recovery update list, select the rom and start the flash
and i have the next error: the "C:\ProgramData\Nokia\Packages\Products\RM-808\RM808_059M7R4_2175.2302.8779.12310_002.vpl has invalid signature."
but if not rename the files and leave them as they are 059Q7C4 ...
stop giving the signature error, but I get the following error: Recovery failes. ERROR: Reported OSBL an error! Code: 0x300FF
ok in the other side if you open the 3 files with text editor
1. RM808_059Q7C4_2175.2302.8779.12310_002.dcp
2. RM808_059Q7C4_2175.2302.8779.12310_002.vpl
3. RM808_059Q7C4_2175.2302.8779.12310_002_signature.bin
you get it in like xml format with the list of files to flash, the names, etc i think its needed to rename it too, and in the _signature.bin file have the signature for the 2 others files the RM808_059Q7C4_2175.2302.8779.12310_002.dcp and the RM808_059Q7C4_2175.2302.8779.12310_002.vpl
so maybe we can try to found a form to flash the telcel variant, maybe changing something in the dcp, vpl and signature files
Any idea is welcome...
thank you very much in advance
Confirm have tried same with same result. Appears OS Boot Loader (OSBL) is rigged on the AT&T version of Lumia 900 so that not even same group RM-808 roms may be flashed.
Cheers

Is this even possible?
I was under the impression tha the AT&T variant is pretty locked up... I might be wrong though, total Windows Phone 7.5 noob since I'm more an Androd user, but I wish I could do this on my backup AT&T Lumia 900 before I sell it.
Let us know if that's even possible... Thanks
Cheers!

It doesn't seem to be possible. The at&t variant has something different about it from the rest of the batch of 900's.

Change the files name, only the product code part, not firmware version, then instead of recover, do the refurbish with the new firmware. I did that with my Rogers with the ATT 7.8 firmware, aand it works.

yes,
but I think you can do that on your ATT with telcel variant, as long as they both RM-808. Just like people with Rm-823 can flash each other's firmware.

That's as far as you'll get with an at&t lumia for some reason.
Interesting... As soon as I downloaded everything that's needed to perform the AT&T Lumia 900 upgrade to WP7.8, I started receiving calls from people on Craigslist wanting my Lumia 900... hahahahahaha
So I will hold on the firmware upgrade and see if the sell goes through...

Hello,
I live in Korea and not an AT&T carrier user. So, I have never received AT&T's OTA.
I tried to connect my Galaxy S7 Active to Samsung Smart Switch, but Samsung Smart Switch says my phone's firmware is the newest version.
My phone's baseband version is G891AUCU1APE7, and build number is MMB29M.G891AUCU1APE7.
Am I unable to update my phone forever?
I want to update my phone's firmware.
I desperately need your help...
Thank you.
ATT only updates there phones OTA... you have to be on the att network to get it to update.

Given that they allow unlocking of the device, that is a ridiculous policy. I can only hope that someone will be able to download the image so that we can use odin.
looking on the S6 Active thread, they find the update downloads on AT&T site, not sure how ?? you can easily find out WHAT update is the newest ..
then either flash via Odin, or 'side' load it ...
but i couldnt find out how they were getting the links from AT&T site to download direct ..
Updating outside USA
in order to update this device outside of USA you should get a At&t SIM card (whit active account), put and seek for updates and will work, I made it a couple of hours and I was able to update.....All this thanks to a friend who lives in Usa and came to visit my country and lend his sim card to do the test ...
Do AT&T have such things as pre-paid sim cards? And could I activate one outside of the USA?

It exists and is called GoPhone, only you would have to do it through some friend or trustworthy person who lives in the USA and can buy it and send it to your country ... is what I will do for the next updates
(Was a scam site, sorry)
now we have these phones rooted, could people in the US with a OTA updates, pull /dump the updates
for us people outside US to flash via Odin ? ...
I'm looking into purchasing this device but have second thoughts due to firmware update availability (not to mention custom ROM support).
Anyway, related to the topic above, I have an AT&T prepaid GO Phone SIM but it is already deactivated/expired. Can I use this old prepaid SIM to update the device firmware outside US?
Side question, what is the difference between SM-G891 and SM-G891A? I see it often when looking for this device.
Thanks.
