AT&T to T-Mobile question, HTC One M7 - One (M7) Q&A, Help & Troubleshooting

If I'm currently on AT&T and want to give the phone to my wife who is on Tmobile......
And I have S-Off, CID 111111, phone rooted and all that good stuff.....
And I have ARHD 81.0 installed.....
Do I need to do anything special in order for the phone to work on Tmobile, or can I just select Tmobile as my carrier when doing a clean install of ARHD 81 since CID is 111111, it would work on Tmobile wouldnt it??
Thanks

it will work as a phone, question is the data and MMS
the APN settings will have to change and theirs a good chance she would be stuck with Edge (dialup speed slow) Data. Where I'm located only a t-mobile phone will get 3g and 4g and the AT&T phones get Edge data service from T-mobile.
The AT&T phone is missing a radio band necessary for T-mobile high speed data

SIM Unlock - T Mobile

Hey guys. I was wondering what steps I need to take to get my Sprint HTC One up and running on tmobile. I've tried everything with no success. I am running 4.3 stock rooted deodexed with S-Off, sim unlock, and the older radio. I am still unable to pick up a tmobile signal. Any help would be great. Thanks.

[Q] Using 4G on Sprint HTC One when GSM is enabled

Hello,
I recently acquired from ebay a used Sprint HTC One M7 for cheap because the guy couldn't unlock it.
I followed all the tutorials and guides here, and got the phone unlocked, TWRP recovery and SuperSU flashed, S-OFF, and a custom rom (Viper) flashed on it successfully.
I am from France and my network operator is Free.fr. I used both the *#*#4636#*#* and the Mobile settings to enable GSM and the phone, SMS, and 3G data are all working properly.
However, my operator allows for 4G LTE as well and I would like to use it if possible, while retaining the use of the Phone itself (making calls, texts etc).
The way it works for Free.fr is that I have to login on their website, and enable 4G manually. The server will then check if my phone has 4G LTE compatibility and enable it if it does, but everytime I try it tells me my phone is not 4G ready.
Is there anyway to do this? A guide or tutorial out there perhaps?
edit: more info:
It seems I need 2600 MHz frequency for 4G to work with my operator, could it be that the Sprint version cannot handle this? Any solutions?

Yeah :/ the Sprint HTC One only supports the 1900MHz for LTE. There aren't any solutions afaik, unless you might want to do a hardware mod, and doing hardware mods on an One is near-impossible.. so you're out of luck.

Ah well, that's alright, at the price I got it for it's still worth it even without 4G. Thanks for the reply!

Hi, could you share your experience of sim unlock the device?
my phone is on 1.57 hboot. I s-off it and RUU to 1.19 firmware. Android 4.1.2. Then I install latest TWRP and Super SU 2.0
Then I download the "sprint htc one sim unlock helper" , select sim unlock.
phone reboot. select " GSM/WCDMA/LTE auto" in *#*#4636#*#*"
Now when I insert my AT&T sim card. it pop up to select carreir, I choose "AT&T", I also choose "GSMUMTS only" in network moode. Also set up ATT APN.
now iin Phone indentity, I could see my phone number,
But there is no signal for the phone at all...
Could you told me your way of doing the sim unlock? Thanks.

I did exactly what you did and I had signal. I am from France so I don't know about AT&T though. With my French operator it works fine now.

OTA Updates Off network?

I know I have been asking a lot of questions lately and I'm no android noob, but I was with cdma carriers soo long I'm still getting used to GSM.
Anyway I have a m7 flashed to stock AT&T 4.4.2, and I am SIM unlocked running my AT&T M7 on Metro PCS on T-Mobiles network, I have checked a hundred times and advanced the phones clock etc... Still It won't find the 4.4.3 or sense 6 OTA... Does AT&T require a handshake from one of their SIM cards to issue updates??

Exactly, AT&T's M7 must be connected to AT&T network to receive ota updates. But you can flash ota updates manually (if they were uploaded by someone and only if your phone is S-OFF)
If doing it manually, it must be done incrementally, you can't skip one.
Can I use a inactive AT&T SIM and grab the OTA over Wi-Fi?

[Q] RUU Question

Hello,
I'm about to buy an AT&T version of the HTC One to use on T-Mobile, the reason being is that that AT&T version supports the newer 1900 MHz LTE that T-Mobile is using in my area while the T-Mobile version of the phone doesn't. If I flash the T-Mobile RUU will that disable the 1900 MHz support? Sorry if this is a stupid question; I'd just like the T-Mobile firmware so I have WiFi calling, etc.

Nobody knows? Everything I've read says flashing the RUU would be safe, I just don't know about the radio part if it will disable the 1900 MHz LTE support.

I'm pretty sure their answer would be flashing a T-Mobile RUU over a AT&T phone is an unsupported operation and will void your warranty. I guess I'll have to be the guinea pig
I won't have the phone until early next week probably, I'll post back what happens.

read this, same question, same answer http://forum.xda-developers.com/htc-one/help/t-mobile-lollipop-ruu-error-155-t3053962
Got the phone, and it works perfectly
Here are the steps I took for anyone in the future who wants to use an AT&T HTC One in a T-Mobile area that has 1900 MHz / Band 2 LTE:
1. Unlock and S-OFF bootloader.
2. Change CID and MID for T-Mobile (TWRP and use MID Changer 1.01 or SuperSU + there is an echo/dd command.)
3. Flash hboot 1.57 <- Very important, earlier versions don't support the encrypted rom.zip that the T-Mobile Lollipop RUU uses. Save yourself hours of debugging and hassle like I did until I figured this out (Google was useless for this.)
4. Run the T-Mobile Lollipup RUU (or whichever version you want.)
What CID and MID? Is it just SuperCID and PN0713000? I have SuperCID (11111111) but my MID is PN07120000. Currently on hboot 1.61, radio 4T.35.3218.16. I want to get the T-Mobile RUU so I can get better reception (my dad gets one or two bars where I am, I get none), but I obviously don't want to brick my phone.
Edit: I'm running the RUU without having changed anything. I am S-OFF. It seems like it's working just fine, it went through "checking CID/MID" without a problem and is going through the process without a hitch as yet. I'll update once it's done.
Edit2: SUCCESS

Sounds like you got it already but T-Mobile's CID is T-MOB010

Will changing the CID have any effect? It's not hard since I'm S-OFF but I'm just wondering. I'm still not getting a signal (for reference, my dad's phone is an HTC One X, AT&T variant, mine is an HTC One M7 from AT&T, m7_ul).

I doubt it, the One X may just have a better radio.

check your APN settings, and so you know you may be limited to just edge data service with t-mobile on the at&t htc one .. your missing the 1700 band that t-mobile uses in most of the country
Well, it seems like all the places I get 4G LTE are on AWS. According to the coverage map I should be blanketed in Band 2 LTE but I've never seen it connect.
Back to the old drawing board... I've seen some stuff about editing NV variables but none of the software seems to work; says it writes the variables but they don't stick.

Yeah the AT&T phone does not have the 1700 AWS Band radio so no amount of software / firmware flashing will help.

You've got it kind of backwards
I'm trying to enable the 1900 MHz band, the 1700 AWS band is working already (LTE Band 4 is 1700 AWS in the specs you copy/pasted)
I flashed the Developer Edition RUU and still nada on 1900 MHz. At this point I'm not sure if the phone just doesn't support it even though it says it should or if T-Mobile's map is way off or they've updated it before actually deploying 1900 MHz LTE.

When you ran the T-Mobile RRU, did it change your hboot version from 1.57 to something else?

Flashing Roms For Other Carriers.

So I am under the impression reading around on here that even if I SIM unlock a sprint M8 and try to use on T-Mobile' network it wont work. Or maybe to be more exact it doesn't get 4G ect, and will be super limited. Well someone told me that is because of the ROM being carrier apecific and since they M8 is the same for all carriers you can flash a T-Mobile ROM on a Sprint M8 and it will work just fine. Is there any truth to this?

No it is not. You can only use cross variant stock roms if you have super cid and s-off too. Still i would suggest you to look for more clear answer but as far as i know if the cid and mid of your phone doesnt match with the software version you want to flash it wont do any good.
It's my understanding that you must use a Sprint compatible ROM, even if you are Super CID and SIM unlock for use on another carrier.

Never do that .. Even though you can flash tmobile rom on sprint , BUT NEVER FLASH A RUU . flashing a gsm ruu on cdma device will brick your phone .
Flashing t mobile rom doesn't unlock it or make it work with tmobile .
AFAIK Domestic sim unlocking is not possible for sprint variant.
