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://xdaforums.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).
[Nokia Lumia 920] Solarenemy68:
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.
[Nokia Lumia 920] colinbo:
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?
[Nokia Lumia 920] petard:
Where did you read this? I've never seen this and I've only read about some people managing to get AWS enabled. They're both the same model number.
[Nokia Lumia 920] Solarenemy68:
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.

[Nokia Lumia 920] petard:
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.
[Nokia Lumia 920] OJ in Compton:
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.
[Nokia Lumia 920] petard:
He did not follow dullerm's directions. Here is the quote for comparison.

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.

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
[Nokia Lumia 920] dullerm:
He did. Uploading the two ROMs he needs right now.
[Nokia Lumia 920] petard:
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.
[Nokia Lumia 920] OJ in Compton:
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.

edit:

Great, can't wait to see what his results are.
[Nokia Lumia 920] colinbo:
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.
[Nokia Lumia 920] dullerm:
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.

---------- Post added at 07:38 PM ---------- Previous post was at 07:30 PM ----------

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

[MENTION=280825]petard[/MENTION] 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.
[Nokia Lumia 920] petard:
##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.
[Nokia Lumia 920] cellneuron:
Great, it looks we will have a simple method to recover AWS in att lumia 920.
[Nokia Lumia 920] dullerm:
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.
[Nokia Lumia 920] petard:
Yeah I tried pressing call, doesn't work on my ATT L920 with latest OTA

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!

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.
[Nokia Lumia 920] ascenx:
Still only Band 2 for 3G...

I started from an unlocked AT&T Lumia 920 on Portico and followed through all the steps here. I reset my phone each time after flashing to a new rom. Just wanted to correct an error here.

[*]Flash to Latin America Mexico ROM: RM820_059S0M8_1232.5957.1308.0001_036

[*]Flash to Global Black Swap ROM: RM821_059Q5C6_1232.5951.1249.1004_044

After flashing Rogers rom in the last step, I figured that I don't like Rogers' branding so I flashed it to Euro Dev again.

I am in a refarmed T-mobile area so H+ is on PCS. However, I am only able to find Band 2 for 3G in the Field Test app after flashing. I am not sure if this indeed enabled AWS on my AT&T Lumia 920.
[Nokia Lumia 920] colinbo:
Trying to get back to pre-portico but it's not letting me from the 1314 Rogers, Latin America Mexico or Global Black Swap.

[Nokia Lumia 920] ascenx:
Today I went to a T-Mobile Store and tried out two SIMs. I tried one SIM card and got very good signal but a "Serving UARFCN" of 512, refarmed PCS. Another one of them seems to be "unauthorized" so I got no bars in the signal strength indicator, however, I saw in Field Test app that my AT&T Lumia 920 picked up "Serving UARFCN" 4384. This is not AWS though. So what is this? Any ideas?
[Nokia Lumia 920] neftv:
Is there anyone that can share the appropriate files to get a unlocked AT&T Lumia 920 use all of TMobile. Namely to enable the aws bands. That navifirm 1.7 application don't seem to get the files for me. Please advise thank you.

[Nokia Lumia 920] petard:
I also had the same issue back in January with my experimental 920 that I had received a replacement for and had to send back in a few days. I couldn't figure out how to get back to AT&T (portico or pre-portico) so I just sent it back with euro ROM.

Why are you trying to go to pre-portico? Did you finish the procedure? Were you able to enable AWS?
[Nokia Lumia 920] ascenx:
Were you able to enable AWS on your experimental 920?
[Nokia Lumia 920] OJ in Compton:
I take it none of you had any luck? Was hoping this wasn't just too good to be true.
[Nokia Lumia 920] neftv:
I guess its to good to,be true. I posted in the Nokia support discussion forum about enabling aws and was told the following

RM-820, AT&T variant:

EGSM 850/900/1800/1900

WCDMA 850/900/1900/2100

LTE band 4 (1700/2100) & 17 (700)

LTE Cat 3 (100 Mbps Downlink, 50 Mbps Uplink)

HSDPA+ Cat24 (42.1 Mbps), HSUPA Cat 6 (5.76 Mbps)

I would believe that all of the above are active by default.

My thinking is that only the refarmed 1900mhz band is possible with Tmobile 4G and possibly Lte band 4 when Tmobile lights it up will know soon enough. Otherwise your on Edge 2G with Tmobile. I don't know how people think this AT&T version of the 920 is a pentaband wcsdma. There is nothing from Nokia to support that is the case. If there is and I missed it show links and a way to get appropriate files. Thanks.

[Nokia Lumia 920] sadude:
This is good info but from what I recall in my reading, it was the flashing of a rogers phone with att firmware that somehow magically disabled the AWS bands in that phone

It was this finding that then the ATT rom is disabling the AWS band and that the hardware is the same. i believe 4 people had gotten the AWS 'working'.

I am also anxious to figure this out as I just unlocked my red 920 yesterday (920). The area by my house is refarmed but since I have wifi it doesn't matter too much but when I travel out and about and go to the city of chicago, i am on exclusive and SLOW edge so i would love to resolve this issue myself
[Nokia Lumia 920] OJ in Compton:
I wish I had the ability to help, I no longer have a 920 and don't plan to buy one again unless someone is successful at enabling this.
[Nokia Lumia 920] neftv:
I not so sure that the 4 people really have aws working at least the lack of response to the AT&T version in this thread does not give me the any confidence. The specs for the USA version and the international version don't even list the 1700. 1700 is only for LTE and only for the america version. Thats the other thing I flash my phone are the bands going to be messed up between the euro version and what the hardware was setup for. Also seems like there is no going back to the At&t roms if all this goes south based on threads in general section. Way I see it this phone now I will get the tmobile refarmed 1900 and maybe get LTE because the American version supports the bands which seems to be shared with At&t on the 1700 lte. Who knows when TMobile will light up lte in the Philly market but I think it will not be remarkable coverage wise if the refarmed 1900 is any indication.

[Nokia Lumia 920] neftv:
For those that flashed your 920 thinking you have aws bands I have a side question. You know how Netflix and Hulu only work in the united states, well will it still be possible to install these apps if there is a different firmware on the at&t version of the Nokia 920? I don't want to lose Netflix and other content because I have a non USA firmware on the phone. I already lost IHeart radio going from pre-portigo to portigo at&t firmware when did a reset. Sorry for the spelling. Can anyone confirm if Netflix will install on different firmware and make sure you can log in. I know that it might install but if you can't log in then its locked out.

To me more important that I don't get locked out of applications than aws bands. Please if anyone can confirm one way or the other it is appreciated. I'm still not convinced though that AWS band is available after going hoops to make it so since two days have passed from my previous posting. I need some confirmation here or how do we do this. Anyone?

Due to the Level 3 service manual for Lumia 920 there are no hardware differences between Rogers and ATT variant. It must be a firmware setting but this could be done by a bandlock certificate. So ATT to AWS could be impossible, but Rogers to ATT and back should be possible.
[Nokia Lumia 920] neftv:
Wow a band lock certificate or something like that. Really, really!! Talk about exclusivity on the At&t version. How about all those who outright purchased the phone. Unlocking the phone should also free the band restriction. At&t is really something else any they can get away with it too. First with the last firmware update and this too.

RM820_059L848_1232.2109.1242.1001_179 - ATT Pre-Portico

If someone has other ideas I'd be happy to hear it - feels like a rip off to have an unlocked Nokia Lumia 920 from one carrier that operates differently from a Nokia Lumia 920 from another carrier even though it is supposed to be the same hardware.
[Nokia Lumia 920] neftv:
I sent a rating 5 feedback via settings in the phone to Nokia requesting for the release of the bandlock certificate since exclusivity is over now. Just like aws not working I expect that lte will only be locked to at&t lte frequencies and not be able to use tmobile when that ever lights up.

Looking at the Level 3 Service Manual on page 7-5 I see two entries:

RM-820 AT&T: EGSM 850/900/1800/1900, WCDMA/HSDPA/HSUPA 900/850/1900/2100 (VIII/V/II/I), LTE 1900/1700-2100/850/700 (B2/B4/B5/B17)

The missing entry on the second one is WCDMA 1700/2100 (IV) which is AWS. This suggests that the AT&T variant is unlikely to support AWS. Thoughts?

If it makes you feel better, you should not have any issue using the 920 on T-Mobile LTE when it's unlocked. T-Mobile uses band 4 for LTE and at&t uses this in some markets as well, meaning that your 920 supports it.

There unfortunately aren't a lot of phones that support the 1700mhz band natively that aren't sold by T-Mobile. Off the top of my head, all of Google's Nexus phones have traditionally had support, and a few non-windows phone Nokia phones like the N8 and N9 do as well.
[Nokia Lumia 920] pete_es:
Yes, but only by firmware, not by hardware.
[Nokia Lumia 920] neftv:
That is a big if because I read in another thread that AT&T made Nokia only allow the part of the LTE band that AT&T uses work and not the rest. So even with the same band support on lte we may not see tmobile lte on this phone.

I wished Philadelphia area had tmobile lte to see. Anyway this firmware changing I just can't see it being conclusive. How do you know if your not picking up the 1900 refarmed frequency? In my area I do get "4G" but not everywhere so I think that is the reason.

As other post have said, T-mo is in the process of redoing their network to support the ATT frequency. However that is a slow process and you are just lucky that they consider Vegas as a rush location and have go it working there already. Most other places will not get your results with the ATT model.
[Nokia Lumia 920] OJ in Compton:
Well, anywhere that T-Mobile has rolled out LTE will give results like his. They seem to be making steady progress lighting areas up, it's pretty decent here in San Jose. He was simply confirming that an at&t branded 920 works with T-Mobile LTE.
