Hello,
I can not get LTE working with my black Lumia 920.
The phone is supposedly RM-821 global version with pentaband LTE support disabled in firmware. Bought in Vietnam from official retailer and I am using it here in Finland where I live (LTE frequencies 1800 and 2600 are used by my operator). There is no 4G option in settings->mobile network->highest connection speed. I can go to field test menu (##3282+call) -> settings and select 4G only there but as soon as I leave that menu the setting reverts back to whatever it was set before. Also no LTE network is found during the time I stay in the menu.
This issue is driving me nuts.
Here is what I have tried so far with no success resolving the issue:
- Flashing in 8-10 different firmwares/softwares (several different region rm-821 models including finnish) with Nokia care suite.
- Called my operator several times and requested and got a new sim card to rule out the possibility that the problem lies there.
- Called nokia customer care twice and they keep telling me that the phone - for being the global variant - has LTE support on hardware level but it is just disabled in software.
- Checked the APN settings. If I select the access point with access point name for 4G network with my operator I don´t get connected at all. It says 3G in the topbar but network simply doesn´t work.
- Done this all in area where there should be 99,9% certainty for LTE-network availability.
So if anyone can point out something that I have missed or could still try please do. Would be highly appreciated!
You say it has octaband support. Have you confirmed what frequencies it operates at? It is possible that even being octaband versus pentaband that your frequency is not in that phones range. Is there any documentation that says what bands your model supports?

Sorry I mean pentaband ofcourse. It is supposed to support the 800, 900, 1800, 2100 and 2600mhz frequencies.

Now that is out of the way, are you sure that your provider has LTE coverage in your exact area? Not just over all but at your exact location? Also is the signal you get at your location normally strong. If it is not strong enough the phone will drop to a lower band to conserve bandwidth.
you may find that nokia has not enabled it yet, they my do so at a later date by firmware .. the CVBG also do not have 4g working out of the box
I am having the same problem.. I bought a 920 when on holiday in Thailand.. now back home and it will not show 4G.. only 3G... whereas my 820 gets 4G fine...
Its an rm-821... and like the original poster i tried flashing a known 4G firmware onto the phone..
Do they actually manufacture 920s that are not 4G ?? I just assumed they were all 4G.... I guess i was wrong..
Have you try this app and manually set for the LTE? just a suggestion

Flash your RM-821 with the Finnish firmware 059Q917 (1308.1) . It will activate the LTE as it did mine.

Just a question, when a new update comes out in the future, what product code shall be used? The firmware's or hardware's?

Updates which are firmware, look at the hardware in the phone to confirm product and region compatibility.
I have the unlocked version sitting on my desk right now.
The only difference seems to be that the radios are not the same?
But I've been reading that the radio might be flashable so it can accept Tmobile frequencies.
One question though, can ROMs from the unlocked version be used on the Tmobile version? Thanks

From what I have read, the T-Mobile H1 can flash any ROM.
The radio flashing is an open question. So far attempts to get the AWS working on the dev / unlocked models have not worked. HTC says they have different radio hardware, but at this point it is anyone's guess if we will ever get AWS working on dev.
If you use the unlocked / dev on TMO, you will get 21 Mb on the 1900 refarmed band, and eventually LTE if you live in an area that has it. Right now there are maybe three areas with LTE.
If you got the 32 Gb unlocked, in my opinion it has no advantage over the T-Mobile model. The Dev edition has 64 gb of storage.

The tmobile version flashed to the unlocked ROM should retain AWS on HSPA+, correct? That's the route I will probably be taking. The additional LTE bands are inconsequential for me - mainly south america and Philippines.

I don't think anyone has tried that yet. I suspect AWS wouldn't work without some modification because the ROM would not support AWS. But I don't think it would hurt anything either.

Yes, flashing ROMs doesn't affect frequency compatibility. All GSM One variants have the same hardware and ROMs/kernels are cross-compatible (international HSPA-only, and EMEA/AT&T/T-moblie LTE). ROMs don't include radio software, and so far at least, radio software hasn't affected available frequency bands.

If flashing ROMs (not radios) to/from intl, US, EMEA models don't affect supported bands, I don't see why it would affect tmobile -> unlocked. Advantages would be no tmobile bloat, no hacks to please the tmobile overloads, etc.

It sounds like you're disagreeing with me or something, but yes, flashing an international ROM on tmo One is great because it gets rid of bloat, can edit APNs to enable tethering, and always based on latest firmware rather than waiting for tmo to push an update. Only downside I know of is no wifi calling. I'm running TrickDroid on mine and it works great.

Sorry, that was more directed at stevedebi's comment. Wifi calling can be replaced with SIP calling so that should be fine.
Warranty problems?
One potential issue with getting the T-Mobile version could have to do with the warranty. U.S. carriers seem squeamish about people modding their phones and threaten to void the warranty for unlocking bootloaders, rooting, etc. That said, I don't have specific info at hand that HTC unlocked phones are much more lenient but seems worth looking into.

Well, most of the new T-Mobile plans come with unlimited hotspot and WiFi calling. I'm not planning to unlock mine. My One is performing fine on the stock ROM, and TMO will update the software (eventually).
As noted above, I'm not sure that T-Mobile looks kindly on having TAMPERED show up on a phone. They might well deny a warranty claim.
For me get the T-Mobile HTC one I had the 64gb edition got tired of the stupid refarm 1900mhz frequency my icon was switching from H to 3G. Now with my original T-Mobile HTC one I get steady 4g icon and good speeds

Switching from H to 3G is just what the radio does; it's how the interface is supposed to work. The T-Mobile version works exactly the same way--and you can see this if you flash an international ROM on your tmo One--but tmo assumes Americans are idiots who a. don't know what HSPA+ is, and b. get confused if the radio idles at "3G" when they expect to have "4G" coverage. So stock tmo ROM just shows 4G all the time, but it is just themed connection icons really. Seems like they're right to do this, which is a bit sad.
Of course, that doesn't mean that you would be getting the same speeds with the dev edition, since even in refarmed areas, you could well get better UMTS coverage over AWS than PCS.

Not to mention that in many cases you get EDGE on 1900 even in refarmed markets.
yeah I was thinking of getting the DE because its 64gb but then I realize that with wifi everywhere, I can just upload pictures or videos to you box account, then delete them to make room, and keep installing apps I want and delete those you dont.
After dealing with 16gb in a Gnexus, you learn how to manage to space

You are right if you go to phone settings-about- network you could see UMTS and HSPS+ it swicthes between UMTS 3g and 4g HSPS+ and my 4g icon stays the same, this also happen to my old HTC one 64gb developer edition but it never showed the 4g icon like T-Mobile HTC one all it showed was 3g and H icons this happens in a 1900mhz refarm area. Look at T-Mobile HTC One as example thank god it has 1700mhz built-in that's why I got ridoff my developer Edition

yes flashing the TMO version on an unlocked rom will allow you to retain the AWS bands tmobile uses for 3g/HSDPA/HSPAP(HSDPA+)

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?
Thanks to anyone that can help out.

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.

AT&T L920 has AWS 3G disabled by default. You must flash an alternate ROM to enable it.

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.

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?

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.

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.

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.

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.

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.
Evening all,
Just a bit of advice, I'm looking to upgrade from my g8x to the v60. As the european/international version is virtually impossible to find, I'm looking at the unlocked USA variants of this phone. Does anyone have this model in the UK and can confirm that it works on 3g/4g OK? I've found different sources stating that some of the bands aren't present in the USA variants - not bothered about 5g, just as long as I can get 3 and 4g on o2 it's fine. Also tried frequency checker but it doesn't seem to list the v60 on there for some reason...
OK so I've just come across the website Kimovil, this seems to be more helpful - looks like the only one that is going to be any use is the Canadian variant of the phone, the USA versions from t mobile/at+t have most of the bands missing for use in the UK. Explains why they go for far less online!
Interesting have you got a link to that site or have a link of where to buy one that will be good for UK
Also looking to buy a v60 to use on the UK
Kimovil.com
Not really found anything other than links for the USA versions of the phone, they don't seem to have the correct bands for most of the UK networks. I'm just watching eBay and seeing what comes up...
I bought an ATT model, unlocked from Ebay. I live in The Netherlands and my provider, Simyo, uses the KPN network with 800mhz (band 20) and 1800mhz (band 3) for 4G/LTE. After inserting my sim everything worked right away. Calls, data, no problems at all. My provider does not support 5G yet
Edit: be aware that you will not receive updates like android 11 (if on 10) or security updates on the V600AM.
I bought the V600AM, I'm in the UK and I can confirm that it works with O2. The only issue is that phone will switch to 2G when making voice calls,soon after hang up it will switch back to 4G LTE.

OK that's useful to know, I'm still not sure about 3g support as where I live in the depths of rural Cornwall we seem to struggle a bit with 4g - it's OK when I'm outside but indoors tends to drop back to 3g, I can use wifi at least. Thanks for the info though

Yeah, the 3g coverage is a thing for me as I tend to only get 4g when outside, it reverts to 3g indoors and I think that may be an issue for me with this phone as it needs to be a daily driver - as far as I can see the USA variants don't support the right bands for UK use....

You could force the phone to be on "LTE Only" with an app from Gstore,but then you won't be able to receive and make voice calls. Not ideal, but considering this phone is from a US network,it will never be 100% compatible with UK Networks. If only someone would find a solution to root it!!!
Which bands use for UK?
Calls will be via 3g if your region coverage that bands.
