Flashing a T-Mobile ROM is your only option, we can't flash other ODIN packages or else we would have used that to unlock the bootloader.

regardless which rom you flash and regardless if you're on the AT&T network or Tmobile network.
Do not Odin flash the AT&T stock firmware on a Tmobile phone even if it's unlocked.
If you do you will not be able to make or receive any phone calls.
You can flash AT&T or Tmobile CWM/TWRP flashable stock or custom zip file roms because
those do not contain the radio/modem images like the Odin flash firmware do.
If you odin flash back to stock Tmobile firmware you will loose root unless you re-root after flashing.
As far as bootloaders go, a Tmobile phone requires a Tmobile bootloader, but you don't need to worry
about that if you flash the stock official tmobile firmware with Odin.
All the other tmobile and at&t cwm/twrp flashable zip file roms found in these threads don't contain
any bootloaders that's why they can be flashed on any unlocked and rooted tmobile or at&t phones.[/quote]
so the hardware is different is that why you cant flash att stock firmware with odin on a T-Mobile s4

i was under the impression that the hardware was the same and the firmware / modem /radio firmware controled the radio Frequency

The hardware is NOT the same.
If the hardware was the same for both the AT&T S4 and Tmobile S4 phones then there would only
be one model for both carriers and both carriers would be using the same frequencies of operation.
It's not the software that determines the frequencies of operation, it's in the hardware.
Another thing is that the AT&T has a locked bootloader, the Tmobile bootloader is not locked.
(Whether the bootloader is locked or not it has nothing to do with rooting)
He is correct here...they are not similar. 2 different modems etc.

No you cant. You have stick with att firmware or else your phone will be a brick.
What would be a better phone to get to use on AT&T? An unlocked T-Mobile S4 or an AT&T branded S4?
AT&T ROMS on T-Mobile S4
I've been attempting to install the stock AT&T firmware on my T-Mobile M919. I understand after reading the thread that this is not possible which is why the Odin flash always fails. I am using an AIO (AT&T) sim card. I have been flashing ROMS built for the I337. Most boot loop after install. Those that install successfully cannot activate the WIFI function on the phone. Both Xperia and Darth Stalker work when installed for the AT&T variety of S4. Today I read the Goldeneye installation instructions which state if the AT&T baseband is not flashed on the phone, then WIFI will not work which is the problem I routinely experience. So my question is should I be flashing T-Mobile S4 roms even though I have an AT&T sim? or do I have another issue? The phone is rooted and sim unlocked. Thanks!
I own a i337M S4 is it possible to flash via odin the i337 att firmware? and have the modem and everything still working? So basically I want to take my Canadian S4 and make it usable in the US? I'm going to be moving in a few weeks.
Hi, I have the same question.
I am planning to install Telus rom v 4.2.2 on Fido S4 which is on Android 4.2.2 Baseband i337MVLUAMG1.
I have unlocked (SIM) the phone using unlock code and Rooted using CF auto root.
Have TWRP installed. Have made nandroid back up.
So here are the steps I am going to follow.
1) Download Official Telus Firmware (4.2.2 AMG) from sammobile.
2) Wipe to factory default using TWRP.
3) Flash Telus firmware 4.2.2 using Odin.
4) Root the phone.(CF-Auto Root)
Can someone please tell me if this is OK?
Are there any chances of bricking the device if you install telus rom on fido phone?
Just want to make it sure before I proceed.

T-Mobile ROM on N900W8

I tried to find something for this specific question, and I apologize ahead of time if it's already answered.
I purchased a Galaxy Note 3 on Best Buy's website, and I got an unlocked N900w8 model. Seems to be the mexican variant, not the canadian version. Still has no kitkat update, and it has LTE.
I have T-Mobile, and would like Kitkat right now, and since the Galaxy note 3 T-Mobile version already has Kitkat, can I flash it with the T-Mobile stock ROM? Or will I run into issues?
From what I have found, both have the same feature set, including the same LTE frequencies.
If knox not already tripped, you can follow this guide to not trip it if you want to root, install custom recovery/rom , also you can go back to 4.3. Otherwise you can flash tmo firmware and there wont be any issue.

Ok so just to confirm, when you say "otherwise", so I can just flash a kitkat t-mobile firmware on this, and it'll work just fine without issue? Talking stock kitkat t-mobile firmware, here in the US on this hardware.
It's not currently rooted at all, no mods done period so far.

[Q] T-mobile firmware on ATT S4?

I was going to do the update to NB1 on my ATT 1337 S4. I'm a little nervous about it, I won't lie I haven't heard many good things about it.
I digress.
My question is, is it possible to put the T-mobile firmware onto my ATT S4? My service is through T-mobile currently and I also read the 4.4.4 update is coming out for the T-mobile S4.

No, You cannot flash the Odin tar for tmobile phones, but you can flash a tmobile based ROM. Check out post 2 here. (Any ROM listed will work for you) ... http://forum.xda-developers.com/showthread.php?t=2616221

How to use AT&T s4 on international network

Hi guys one of my friends bought a S4 in the US, It's AT&T locked SGH-I337 so can't use it with sim in our country (South Africa)We have two models of S4 here, the I9500&I9505. Was wondering what the right steps is to get the phone working? Must I root the phone and flash custom Rom & kernel or just unlock sim card? I'm not new to Rooting or flashing Roms but haven't fidled with carrier locked phones before. And is it possible to use custom Roms from At&t in other countries thanks in advance [emoji2]

The Sgh-i337 is basically the same as the gt-i9505 EXCEPT for ATT locking the bootloader on that model.
You CAN Sim unlock it so you can insert your Sim into it. You will have to reach it a bit though. It helps if you know what firmware is installed on the phone. If it is MDB, MDL, or MF3 it would be easier to do I believe. Either way look for the threads about unlocking.
If you have NEWER firmware then there are separate threads for it, and it will more than likely need to be rooted, flash a older modem, then perform the Sim unlock from the menu. If you cannot find the correct post I can help look for it later.
Just reply back with WHAT firmware and Baseband you have installed on the phone and we should be able to help you further.
If you do have MDB or MDL firmware do NOF update it...

Thanks for reply ,I have NC1 firmware and I used Method 3 on this guide http://forum.xda-developers.com/showthread.php?t=2595457 .SUCCESS!
Could you recommend a modem I could try other than MF3 as the signal isn't that great ?

Not sure which would work best for your area. You can download and try any/all of them until you find one that works best. You can switch back and forth with no issues without worries

[Q] Can I flash Tmo Stock Image on AT&T Model?

Just ordered my wife a G2, it is unlocked however it is the AT&T variant and we are on Tmo. I have read that someone took a Tmo rom and made it possible to flash this to the AT&T model along with the KK baseband so that we can use Tmos wifi calling. However I would like to know if I can simply just flash a Tmo stock image and flash the KK baseband if this will work or am I looking into this all wrong?
This is where I read about the Tmo on AT&T rom:
http://phoneprouser.com/lg-g2-rom-that-supports-wifi-calling-on-att/1007/
Can anyone tell me if the ROM mentioned in the link above is this the latest ROM for the G2? Thank you in advance.
Side Question, if I want to flash Cyanogenmod and still want to retain the wifi calling can I flash the Tmo rom along with the aforementioned KK baseband?

THIS IS AN ABSOLUTE AND COMPLETE NO GO, FLASHING A FACTORY IMAGE FOR A DIFFERENT MODEL CAN HARD BRICK YOUR DEVICE, IN FACT I'D PRETTY MUCH GUARANTEE IT!!! GO INTO THE ATT DEVELOPMENT THREAD AND FIND SAID T MOBILE ROM FOR YOUR DEVICE, FLASH THAT IF YOU WANT TO. As an answer to the side question there is no way to retain wifi calling on cyanogenmod, especially on a non tmo device. Finally as for the baseband find out what baseband the respective ROMs need (the tmobile one for ATT G2s or the CM build you choose to use).
