I have found (somewhere in this forum) that I am able to flash a rogers rom to att's lumia 920 HOWEVER, does the color matter?
I have a cyan att lumia 920 and am considering flashing the rogers rom but I am not sure if the color variant matters since rogers does NOT have the cyan model.
Please, anybody with enough knowledge out there, could you let me know????
THANK YOU SO MUCH IN ADVANCE!!!
I don't think the color variant matters. I've flashed rogers black rom to my yellow att. By the way, up to now, it seems impossible if you wanna flash back to att rom.

thank you for your answer! So, if I flash to Rogers then want to come back to att, I won't be able to? That doesn't make any sense! Well, none in my simple mind!
att to rogers than rogers to att
actually, I have a nokia lumia 920 and I have flash countless ROMs from different places around the world and I can always go back to the original Rogers ROM. i'm at the moment using a Latin America ROM from Argentina unbranded, and working LTE. it is different then the one from Rogers. more options on the phone. by the way its the 1232.5957.1308.0002, I think rogers is now releasing an update. any how, if I can flash so many ROMs from different providers you should be able to go back to your ATT ROM
Can anyone confirm who flashed Rogers rom on ATT 920 was able to get 3G / 4G on Tmobile network? I switched to tmobile and I am finding I only get edge but I have not seen a confirmed response if flashing a rogers rom will work? Thanks in advance

Unless you're in possession of the Developer or Pentaband version the AT&T variant will not run 3G/HSPA+/4G LTE on T-Mobile network and then only HSPA+ when T-Mobile "refarms" 1900 MHz.

Have you bothered to search? You can't unlock the AT&T L920 yet so even if it worked, you wouldn't be able to use it on T-Mobile for another 6 months. There's no way to know if it even enables the 1700MHz band unless someone flashes the rogers firmware and then goes to roam on some carrier with 1700MHz with their AT&T SIM card.
you can flash Rogers ROM to the AT&T Lumia 920 and vice versa no problem. those are the only two devices that i know you can flash with any RM-820 ROMs as they have the same device/model ID, RM-820. tried flashing RM-821 ROMs onto my Lumia 920 and it didn't let me. even the developer ROM did not let me flash it. i'm using Rogers Lumia 920 though, but i have an AT&T Lumia 920 ROM as well, and flashed on both.

Will the rom disable the AWS frenquency or it will keep it?
I was really hoping this would at the very least allow me to use my Rogers sim card in my ATT 920, since the recovery file included a suspicious looking file named something like *Rogers_ATT_FIDO_simlock.bin* or something similar. But flashing the Rogers rom does nothing in terms of unlocking for the ATT Lumia

Well in term of flashing, it won't unlock your phone at all. The unlock mechanism bases on your phone IMEI. Flashing can only debrand your phone to whatever you want. Furthermore, flashing some variant might allow the phone to receive firmware update from that variant which could lead to potential enable some features.
so if you flash this ROM does it debrand all the AT&T crap? Does it also let you use internet sharing properly on another carrier?

Maybe or maybe not. Someone need to try to see. Tethering is just only the software inside WP8, but sometime it depends on the firmware version that allows it to be working properly.
Guys this is HUGE and as I will explain bellow, is exactly what we were waiting for.
The method reminds me a lot of what we used to do with Nokia Symbian devices, we were able to change the device product code, product codes were broken down per countries and regions and then re-flash the device with the country specific firmware. This is how we use to debrand and add local languages to the Nokia Symbian Devices.
Now assuming that the German Guide is accurate and we can successfully flash the Rogers firmware to the AT&T Lumia 920 and the opposite, since this is the exact same hardware here are some key points:
1. First and to answer creamhackered question. NO by flashing AT&T phone with Rogers firmware, even thought it will take off the AT&T crapware, it will put in the Rogers branding. Rogers firmware though it only contains the Rogers Logo on startup screen and the Rogers my account App pre-install, which you can uninstall manually, nothing major but its still Rogers Branded.
2. Now this is the HUGE point and as of now I didn't saw anyone speaking or realizing it. There is a third Lumia 920 based on the same hardware and this is the Developer Edition which includes a pure/clean Firmware completely unbranded. Even thought the Developer Edition firmware is not yet available to the server yet, its only a matter of time until it pops up to the Nokia Update servers, I personally expect that to happen with the first major Windows Pone update. In other words if that happens and if that German Guide works, then we will be able to completely debrand the American variant of the Lumia 920 by flashing on them the Developers Edition Firmware! Especially the Rogers models that does not contain a carrier logo on the phone, will be exactly the same as the unlocked Lumias they sell in Europe, with the American Bands!!
Finally, assuming that the AT&T models will be lock for a couple of months (remember branded and locked devices are different things) the only negative aspect is that the Rogers Lumia 920 (which is unlockable(!)) only comes in Black for now, the Yellow color is rumored to also be available soon, but that's about it.
Again this is HUGE!!

Try tethering to see if it will work with AT&T phone. Now if AT&T 920 can be unlocked, we could see if the Rogers firmware could enable the AWS band or not.
No , I got a message that said, you have no cellular connection check your connection and try again , everything works very good on my Lumia 920 ,mms , internet , but I don't know why a can not turn on internet sharing but i really don't use it

That because the Rogers firmware might block the tethering. There is a way to work around that has been posted in xda. It involves the process of adding another keyboard to trigger update and then tethering will work. Not really sure if it will work on Rogers firmware or not, but it works on dev firmware.
I already tried that trick with no luck and change my apn setting to see if it work but nothing happen ( this is the apn that I have, apn is only the word "phone" ) and my internet work great , one thing that I notice is that I have the option to choose 2g,3g and lte with Rogers rom

i have gotten so confused and frustrated trying to figure out which one will work on the Bell network with the proper LTE frequencies....arrgggg
does anyone know where i can go and buy a RED 920 unlocked that suppose the correct BELL frequencies.
please help before i go buy a HTC 8X or worse yet an Iphone
Well hope you don't give up to easy. According to the wiki page for Bell Mobility they use 850 and 1900 MHZ. Just google "wiki bell mobility" I didn't think there is much variation between Nokia Lumia 920s but I guess there is when it comes to LTE ability.

Hi everyone,
What settings can I use to configure my phone to T-mobile? I have an ATT unlocked 920 and I only get E signal. At times it switches to 4G and it drops. I read many posts about changing connection speed but I don't have the option. Is there a firmware that I should install in order to get the most use out of my phone?

AWS stands for Advanced Wireless Services (wikipedia). It uses 1700 MHz and 2100 MHz bands, and only a few phones support these bands.
So there no way to enable 4g on a AT&T Lumia. I love this phone but if there no way to fix this then what the point on having a slow connection
I have it enabled after they gave me the unlock code. I haven't done anything special to enable it apart from the regular phone updates. I'm not in the USA.

Yes, you will have 100% access to ALL of T-Mobile's network.
BUT the European ROM does not call HSPA+ "4G", it says H+ in the status bar. The European networks never followed T-Mobile's bull**** of calling HSPA+ a 4G network.
Look at the RM-821 column in this chart to see what each connection type will be labeled with a European ROM.

If you WANT I believe you can flash the Rogers ROM after flashing the Euro Dev ROM if you want the T-Mobile connection labels. Rogers and AT&T L920 ROMs also get updates before the European ROMs, so that is another thing to consider.

If you are able to connect to an AWS network. I personally use AT&T so I can't test it out, just repeating what others have said. What I know is that people with Rogers pentaband RM-820s flashed the AT&T ROM and that disabled AWS. Flashing Rogers back didn't re-enable it. So it seems that some ROMs like AT&T reprogram the bands and some like Rogers don't. I don't know any of this for sure, though.

The most important question now is - which ROMs can reprogam these bands back. With TMo its hard to confirm you are actually getting AWS and not the 1900 MHz 3G. I'm waiting for someone to confirm that with a true AWS carrier (Wind, Mobilicity).

Yeah if you're in an area with 1900MHz 3G then it is impossible to tell I think. I do not believe the 920 has any good diagnostics app.
Reading through the forums though multiple people have stated that AT&T ROM disables AWS and that euro dev ROM enables AWS. One person stated that the euro dev ROM did not enable AWS and instead he flashed through a ton of different ROMs including some latin america ROMs before finally getting AWS enabled. It's all in the thread I linked to earlier from January.
I have seen this question asked multiple times on this forum so I thought I'd just make a thread.
The AT&T Lumia 920 has the hardware to support pentaband 3G including AWS. This means you CAN use it on T-Mobile and the other Canadian AWS carriers like WIND and any of their MVNOs. Unfortunately it is DISABLED out of the box. You will need to flash an alternate ROM to enable the AWS band!
You will need to install Nokia Care Suite and flash your phone to a different ROM. This will WIPE your phone, but it will enable AWS 3G!
Just flashing the Euro Dev ROM should get enable AWS 3G. It is for the RM-821 but you can flash RM-821 ROMs on the RM-820 without issue. I believe the only difference between the two models is what signal amplifiers and antennas they have installed as their ROMs are cross-compatible.
Check out this thread from January for posts from people who have gotten their AT&T L920 working on T-Mobile AWS. These were some of the lucky few who got their unlock code before May 9.
http://forum.xda-developers.com/showthread.php?t=2097815&highlight=aws+3g
NOTE: ONLY FLASH RM-820 OR RM-821 ROMS! Do NOT flash ROMs for any phone other than the Lumia 920 to your Lumia 920!
I can't offer you any support and am obviously not responsible if you brick your device (though this really shouldn't happen).
I thought only the Rogers 920 was Pentaband. The AT&T version actually has a different transceiver in it which puts a physical limit on the bands it uses.
Detailed Steps are Needed

I have an unlocked AT&T Lumia 920 and would like to enable AWS 1700/2100 for WIND Mobile in Canada. I have flashed in the following order using Nokia Care Suite 5.0.0 (2013.1.3):
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
No luck bringing up WIND on AWS 1700/2100, whereas my Rogers Lumia 920 is bringing it up on 3G/4G. Everything I have seen is pretty general instructions which leaves a lot of details out so this is the best I can do. Anyone else manage to do this that can provide more detailed instructions?

In one of the many threads discussing which phone is better, the Rogers or the AT&T version. Check out this page, I was even corrected in the fact i thought they where the same till several said otherwise.

I think you might have posted an incorrect link. No one says anything like that in this thread.
And if that were the case how come multiple people have reported success enabling AWS on the ATT L920? Plus that doesn't really make sense for it to not have the hardware to do AWS 3G because it has the signal amplifier to do AWS LTE which runs on the same bands.

There's only 1 user who has explicitly stated that they (possibly) weren't just connecting to refarmed 1900mhz towers unfortunately. Still, as someone who's been browsing these forums for months hoping for some kind of breakthrough, I hadn't seen that post and it gives me hope.
Colinbo, why don't you shoot a private message to dullerm and ask for more details? It certainly looks to me like you followed the steps correctly from what you posted.

He did not follow dullerm's directions. Here is the quote for comparison.

To follow up my previous post: after flashing some more, I managed to enable the AWS band on my AT&T Lumia 920. Unless T-Mobile lit up a 1900 tower just in the few minutes that the phone was rebooting after flashing GLOBAL BLACK SWAP, I am certain that I can now use 3G on AWS with it. 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

Also more than one person has claimed to have AWS 3G working. Not only dullerm says he enabled it but so do these THREE other people, for a total of 4, just from that one thread.

DAMN! thanks mate , I just flashed RM-821 VAR EURO1 DEVELOPER firmware on my device it enabled AWS. I was skeptical flashing RM-821 firmware on RM-820. My developer device is back to running on HSPA on T Mobile . Now question is if it enables AWS for all those unlocked devices , which I think it should.

Just tried a T-Mobile sim and it looks like I have AWS enabled now too on my sim unlocked att 920! Now the only thing left is to make sure LTE still works...

what story, or what phrase or how many phone calls...pretty much coach us what keywords to use to convince AT&T to persuade them to give us the unlock code for our 920's
Any feedback would be great. Thanks

for the latin america roms, debranded and no LTE, did you get "4G" from att service, not LTE? I have a AT&T Lumia 920 on Straight Talk, and they dont get LTE so I wont miss it. but if you can confirm. I will flash to my hearts content this weekend.
THanks

In conclusion I have to believe the ATT L920 is fully capable of supporting AWS 3G.
So it seems that if simply flashing the Euro Dev ROM does not enable AWS for you, try flashing following the directions quoted above in this post including flashing the Latin America ROM

That's great. If we can get a fully reproducible method of enabling AWS on the ATT L920 I'm sure a LOT of people will be happy.
I unfortunately can not do any testing on my own L920 because I have AT&T AND I live in a refarmed T-Mobile area so I wouldn't be able to tell if I'm on AWS or 1900MHz.
H+, H and 4G indicators are all capable of showing up if you're connected to a 1900mhz tower on T-Mobile though which is why I'm still a bit skeptical. I believe dullerm since the chances of a 1900mhz tower going up while he was doing the tests is pretty slim. Colinbo is using his phone on Wind in canada which does not have 3G on 1900mhz, so if he can get it working it'll be definitive proof for me that this method does work.
And you're right, it seems he missed this step to flash the Portico LTA1 MX ROM.

You are correct - I was unable to locate the product code for the LTA1 MX ROM. I now have the product code thanks to dullerm's PM: 059S0M8
I'm pulling down the LTA MX1 bits now through NCS firmware download. It's slow so I'll re-attempt the flash tomorrow and report back. My plan is as follows:
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 Latin America Mexico ROM: M820_059S0M8_1232.5957.1308.0001_036
Flash to Global Black Swap ROM: RM821_059Q5C6_1232.5951.1249.1004_044
Flash to Rogers ROM: RM820_059Q6W4_1232.5962.1314.0000_156
As a pre-caution based on a post I saw somewhere I will also use the "Reset your phone" after every application of a ROM to ensure there are no old config values kicking around.
The comparison device I have is an unlocked Rogers Lumia 920 which is connecting to WIND showing 3G/4G indicators -- not sure if there is any way to tell which frequency it is using.

OK, that's great that you can get the missing ROM(s) yourself. My upload is awfully slow (or the ROMs large). Let me know if you still need them.

There is even a really definitive proof for it - you can check which tower you are on in the service menu:
Go to the phone app
Enter ##3282 and call; this will take you to the service menu
Choose "3G Reselection Status"
Look at the value for the 2nd line "Serving UARFCN", which gives the active downlink channel
If the UARFCN is 1xxx or 2xxx, you are on AWS (1700/2100). If it is below 1000 or 9xxx, you are on PCS (1900). This is not exact but good enough to tell AWS and PCS UMTS bands apart. And T-Mobile only uses those two bands for UMTS so the 1xxx-2xxx rule is easy to remember for on the road
For the exact channel numbers, please check this page:
http://en.wikipedia.org/wiki/UMTS_frequency_bands#UMTS-FDD
@petard You might still be able to tell the difference. T-Mobile is only deploying HSPA+ 21 on PCS (as far as I know) while on AWS they deployed HSPA+ 42. Probably not everywhere, though, and depending on the load of the tower, it might not make a difference after all. Just some detail to add.

##3282 and ##3282# don't do anything on my 920. I'm using AT&T ROM though. I am not going to flash it though, WP doesn't offer complete backup/restore and the 920 I experimented on I wasn't able to get it back to running the AT&T ROM. It was my 920 with dust in the FFC and I experimented with it when I got my replacement and before I sent the old one back.

Did you try typing ##3282 and then pressing "call"? Pre-portico did work without hitting call (#3282#, I think) but Portico ROMs (both AT&T, if I remember correctly, and Rogers) do require pressing call.

ATT Lumia 920 on Tmobile
Hi all,
I would like to know if anyone had success using an ATT lumia 920 on Tmobile. I see some have had success. I would appreciate if someone could share the exact steps that would make it work.
I am planning to buy an unlocked ATT 920 (from amazon) and then try making it work on Tmobile. Any help would be appreciated.
Thanks!
Rom locations.
I have NaviFirm Plus 1.7 and its not accesing any files anymore.
I was wondering if anyone can share the files needed to make the ATT Lumia 920 completely work with TMobile USA. I have a you sent it account if that helps. Thanks.
Hello, I have the AT&T's Lumia 920 (RM-820). I want to flash my local carrier's ROM over the AT&T, becuz even though my AT&T 920 is fully unlocked by AT&T itself, LTE doesn't work at all here in my country, only once did for a few mins when I purchased the SIM Card with LTE capabilities then, nothing. But when I go back to USA, LTE works fine either on AT&T or T-Mobile. So my logic is that, if I change the ROM to, lets say, my local carrier's ROM, LTE will work, because somehow, this ROM is blocking it or something and I know RM-820 works with LTE bands 1900 and AWS which my local carrier uses here.
My question is, is there a way to change the ROM from AT&T's to other carrier's?
I've been looking for an anwser but I couldn't find it.
Thank you for your help in advance.
Cheers.
Flash with pre-portico roger's rom, after update to portico via ota, and flash with ROM CV Mexico.

Dear @Axl456 could you please post the link to that process?.
Here also I'm adding screen shots of my problem. Maybe this will clear things up regarding my problem.
Thanks in advance for your help. Cheers!
