No, you should run the RUU's in the order given so that the firmware gets updated properly. The RUU should update the firmware and ROM. Keep in mind that the AT&T variant phone doesn't have all of the T-Mobile variant's bands but in most locations you will get their LTE.
Which band?
The AT&T Version of the M7 does not have the 1700/2100 HSPA band that T-Mobile uses for their "4G" (Not 4G LTE), unless you live in a refarmed area where it uses the 1900 band. It shouldn't be much of an issue because the Band 4 LTE T-Mobile uses is on the same 1700/2100 frequency, which the AT&T M7 does have.
In short, you won't get fake 4G often, but you will get LTE (In most cases, no Band 12 on the M7)

Seems like most of central CA from SF to LA and areas in between have band 4 lte and band 4 hspa. 1900mhz
Ill switch back to the nexus 6 thats in my drawer when band 12 is in fresno.
Although I am missing one hand usability that i cant do with nexus 6.
But other than the gs6 there are no other good band 12 devices. I was going to get the z3 until it was pulled
I recently got notice from T-Mobile that my current phone will not work with changes they are making to the LTE network. So, I was looking to get the M7, but I'm having trouble finding out if the M7 will work on the changes they are making to the LTE network. I like the info I've read about the M7, and the price seems about what I would spend. Anyone understand the LTE stuff at T-Mobile?
I want to make sure I get a new phone that isn't just on one band, if that one band is not as prevalent as others that are not supported on the M7.

I know the Jetstream was designed to be run on AT&T and Rogers, but I am curious if it is possible to flash a radio to enable usage of T-Mobile's HSPA network, much like the Samsung Galaxy Note has been enabled to, as seen here.
Can any of the amazing Devs out there shed some light on this?

jdavis08, Simple answer is yes. It is a standard 2G / 3G / LTE (AT&T / AWS band) phone. So you can use it on ANY 2G / 3G / LTE network with a SIM. But you may need to break the SIM Lock on any handset.
Just wanted to clarify. The Jetstream is 2G/3G/LTE /capable, 2G (GSM): 850/900/1800/1900MHz, 3G (UMTS/HSPA): 850/1900/2100, and LTE: 700mhz & AWS-1700/2100.
Currently, T-Mobile only uses the AWS for their HSPA+ network, not LTE (from what I understand, AWS will be transitioned for LTE and 1900mhz refarmed for 3G/4G early 2013) - and if I'm not mistaken, the HSPA+ is only supported by the "3G" band of this device, not the "LTE"
So - to make a long story short. I am a T-Mobile subscriber with various "4G" phones from T-Mobile. Their 4G only works if the phone has a radio with AWS for HSPA as T-Mobile (unlike AT&T) does not use the 1900mhz for their HSPA (yet). I own this tablet.. It has been SIM unlocked and it simply does not get anything above EDGE... and I live near and visit major cities in Washington State, Seattle/Bellevue/Tacoma, which definitely have TMo's 4G coverage.
I know I should just cool my jets until TMo rolls out the network upgrades, as I have no interest in joining AT&T. I was just curious if there was some way to "trick" the phone to use the AWS frequencies for HSPA, like the Galaxy Note has been made to do as the radio specs are identical.
I know that the Note was enabled to do this by flashing another radio. Support is minimal for the Jetstream these days... so I was just reaching out.
Thanks guys
So since AT&T uses bands 4 & 17 for LTE (700/1700/2100MHz) and according to the Developers edition has 700/850/1900MHz then to me that looks like the Developers edition can only access AT&Ts 700 LTE bands.
Is this correct?
Seems to be correct.. but im not a expert when it comes to network bands

The Developers Edition page shows the following: LTE: 700/850/AWS/1900 MHz (US)
This would mean it supports 700, 850, 1700, 1900 and 2100. AWS refers to Band 4, which is 1700 for uplink and 2100 for downlink. Unless something in AT&T's white sheet is missing, the Developer's edition supports two extra bands that are used in some European and Asian countries.

Finally someone can give me a sensible answer! :thumbup:I read from another thread that T-mobile LTE works on AWS 1700/2100 but the unlocked new one does not have the two frequencies in LTE. Apparently, that was a wrong info. I am going to move to DC and hopefully my dev. new one will work on T-mobile LTE in DC.
Be Vegan, Make Peace ＼(^o^)／
Because it's radio supports these extra bands, will there be any software incompatibility between the Dev edition and the AT&T one? I'm trying to find the proper forum for Dev edition development!
Is the Developer edition basically an AT&T One with extra bands enabled? Are the AT&T and Dev editions different model numbers? I have so many questions, but so much excitement...

T-Mobile's LTE frequency is on Band 4, so as far as using the Developers Edition on T-Mobile USA, you will certainly get LTE as long as T-Mobile has it running in the area, and default to 3G/HSPA+ since it does support PCS band (1900 MHz), albeit this coverage may suffer as the phone is missing the AWS band for UMTS.

Their device identifier code will certainly be different, so HTC will make sure you can't run the Developer Edition's RUU for the AT&T phone. As far as custom ROM is concerned, I don't see why you can't use the same ROM as long as it's not touching any other partition other than the /system.

Yes... I hope I won't travel around next year and will stay in DC most of the time. I am currently using Straight Talk with my Droid DNA, and it has good coverage, hspa+ most of the time. But Straight Talk does not have LTE. I am so ready to feel the speed of LTE! But it seems like if I would be outside of DC, my LTE experience will drop to 2G.... Anyway, at least I have the freedom to change back to Straight Talk if I have to.

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

Hi guys,
I am on T-Mobile prepaid plan. I bought a Lumia 920 from Singapore few months ago in anticipation of the 1900 refarm from T-Mobile. But while the default APN profile has been updated to "T-Mobile LTE" from the carrier from months ago, the max speed I see now is 3G in Chicago. I've done some research and tried a couple of the following:
1 Added new APN under epc.tmobile.com
2 Enable ENS
3 Limit the connection speed to 3G instead of 4G
But none seems to bring me to the LTE speed. I thought maybe because LTE has not arrived in Chicago yet, but few days ago I went to one of the T-Mobile store and found that their demo Lumia 925 showed LTE. The stuff from the store said because I am using an unlocked 920, LTE is not supported. I don't think this is the right answer.
Does anyone has the same issue with your international 920 under T-Mobile in the US?

Wow I just checked, it's indeed a RM 821! I did a search and found the following info from WP Central forum:
RM820 is the North American variant. Has pentaband UMTS (850/900/1700/1900/2100) and North American LTE bands.
RM821 is rest-of-world (except China). Has quadband UMTS (850/900/1900/2100) and European LTE bands.

Just because it supports the 1900 band, does not mean that the ROM and hardware are setup to support LTE. The market the 821 was released for does not have LTE so the protocols where never implemented in that model. The 3G you see the phone operating at is the highest speed the market it came from supports. So that is the highest protocol that was installed into that model. You may want to sell it and get one of the other models.

Hi t_huankiat,
To the extent of my knowledge, T-Mobile has only deployed LTE on the 1700/2100MHz frequency band (different from 2100MHz, that is IMT) commonly known as AWS spectrum or Band 4. The only variants of the 920 that contains these are RM-820 models. The good news is, an unlocked AT&T Nokia Lumia 920 can be used on T-Mobile's LTE network because they both use AWS spectrum to deliver LTE service. The downside is that in areas without LTE or refarmed HSPA+, your service will drop to 2G. In order to prevent these shortfalls, the only RM-820 variants that run on AWS HSPA+ are the Canadian and Developer Edition, given out at Microsoft BUILD 2012.
You may be thinking, what is with this confusion. Previously, T-Mobile USA rolled out their 3G HSPA network on AWS spectrum, because they hadn't won any PCS spectrum (1900MHz). In the Americas, AWS spectrum was not deployed as prevalent as PCS. The result, T-Mobile required special handsets to access 3G. When they transitioned over to HSPA+ and DC-HSPA+, they continued to use AWS widening the compatibility gap. After the AT&T/T-Mobile buyout fell through, T-Mobile gained PCS licenses as part of the deal. T-Mobile, shortly after, announced the jump to LTE and the refarm of HSPA+ (current 3G/4G service) to the PCS spectrum. As of now, the refarm isn't fully complete so some areas still broadcast 3G/4G on on the AWS spectrum. To add insult to injury, these areas do not have have LTE deployed either. Summing up what has been said, the best options for a seamless wireless experience is to use a Nokia Lumia 925 or find a non-AT&T RM-820. If you look on eBay, you will find a few for sale right now. I really hope this helps!

I should have done more research before I bought the phone! I did not realize 920 has so many variation even in Singapore! While I will miss the LTE, I can live with 3G speed since I don't use the phone for streaming or anything bandwidth intensive.

The main reason I got the phone from Singapore was because it supports 1900MHz and it's in Chicago now. But I overlooked the fact that the ROM matters too. So now I am pretty much stuck with 3G speed. It's a lesson learned, I will have to be extra careful next time when I get an unlocked phone. Thanks for your insight!

The main reason I got the phone from Singapore was because it supports 1900MHz and it's in Chicago now. But I overlooked the fact that the ROM matters too. So now I am pretty much stuck with 3G speed. It's a lesson learned, I will have to be extra careful next time when I get an unlocked phone. Thanks for your insight!

Don't worry, you will still be able to use their DC-HSPA+ network, where available. This technology is capable of up to 42.1Mbps theoretically. Even before T-Mobile began deploying LTE, their DC-HSPA+ network was usually testing faster than Verizon's LTE network. While you may not see LTE until you upgrade to an AWS capable handset, their "fallback" 4G should suffice.

According to the specs I've been able to find, the T-Mobile HTC One has LTE Bands 4 and 17, while the AT&T one has bands 2, 4, 5, and 17. As I live in a rural area that's been refarmed to band 2 LTE. Would the RUU I'm using interfere with my phone's ability to pick up the LTE?
While in the same area, it says it's getting LTE on band 4, but according to the coverage map and my previous experience, it should be on band 2.

Let me see if I understand, you have an AT&T HTC One and you want to run a T-Mobile HTC One RUU?
Did you change your MID & CID to reflect the T-Mobile MID & CID?
Assuming you did the above and have a T-Mobile sim you should get LTE if it is available in your area.
I have a DevEd on T-Mobile and was able to get LTE when it was available.

I've installed the RUU and changed the MID and CID, I'm getting LTE, my question is if I will be getting the quickly deployed Band 2 LTE T-Mobile is using, as it seems to be exclusive to the AT&T model, and was enabled with a software update AT&T provided.

If your phone has the bands then you should get it when it is deployed to your area.
