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

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.

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.
Ok. so after being with AT&T since 1998, I went to T-mobile and activated an account today. Last night I also did the mod enabling all the T-mobile AWS, HSPA & LTE bands on my AT&T Galaxy S4 and it was a success. Everything works great, I already have the T-Mobile Sim card installed, and T-Mobile LTE and HSPA is very fast.
I've been flashing ROMS, Kernels and radios for several years on many many different phones and tablets, However this is the first phone I've delt with, with a locked bootloader and also the first time wanting to use a different carriers ROM. The phone is already rooted, with TWRP recovery and I'm running CM 10.2.
Should I flash a T-mobile radio and ROM now that I plan on sticking with T-mobile. If I do, can I flash any T-Mobile based rom, and TWRP will automatically Loki Doki it or whatever it does lol? I don't usually have these questions, but this locked bootloader crap really sucks. The phone is only a month old, so I don't really want to buy a T-Mobile version when I got all of T-Mobile's bands working.

You need to flash the rom, then your loki doki kernel, I do not recommend flashing a different radio, that could brick the device, although, it has been done, and I think our MDL and MF3 modems are sufficient enough to get the correct speeds for your device.

Go to my guide here, at the bottom of post #1 is a patch called loki-doki.zip, that would be what you flash after every rom, I do that everytime I flash roms.

Hey guys,
I unlocked my galaxy s4 from AT&T and now I use T-Mobile. I was wondering if I could use the t-mobile rom since I would like to use the tethering and wifi calls from it.
I don't really want any custom rom, just because I'm fine with the carrier ones.. so I searched somethings and I figured out that I could use the t-mobile rom with loki doki.
Can I just instal the stock firmare of t-mobile? (It would be the M919UVUEMK2)
By the way, right now I'm running the MF3 and idk why I don't receive the OTA update (never received, I suspect that's because I unlocked it)
I found some other posts but unfortunately it doesn't contain enough information.

I just brought a S5 Verizon off craiglist and in need of some help. Stepping back in to the samsung modding is a bit overwhelming now. Seem like a lot has changed.
The guy who sold it me the phone said he had a cricket store flashed the rom so he can use it on metroPCS. I use T-Mobile so i put in the sim and everything seem to work. I had to manually program the APN for 4g data.
I want to update the phone to lollipop rom so i found a site (http://www.galaxys5update.com/galaxy-s5-stock-firmware/) with all the stock rom. Upon looking up the current build number of the rom on the phone it is KTU84P.G900VVRU1ANK2. Comparing the G900VVRU1ANK2 with the stock firmware site above, the current rom on the phone is Verizon. So the rom is Verizon but still work with Tmobile sim/network? This is kind of confusing.
So to update to lollipop, do i download the lollipop version of Verizon or TMobile? I havent been in the samsung scene since the Vibrant so hopefully you guy can clarify how to update the phone. Thanks.
Here are the information about the current rom (stock i think):
Phone name: samsung-sm-G900
Model number: SM-G900V
Android 4.4.4
Baseband: G900VVRU1ANK2
Build number: KTU84P.G900VVRU1ANK2
Hardware version: G900V.05
Gee - I would like an answer to this too.

You must download the firmware for Verizon.
So only Verizon roms still for s5? No custom carrier roms or universal type roms are available to change carrier?

If the phone is unlocked you can use it with a SIM card of another carrier, but you can't install a ROM of another carrier.
So I've spent a few hours searching XDA to find the right resources on how to flash a different U.S. carrier's GS7 Edge firmware on the T-Mobile branded device. I found out that since all the internal hardware for all U.S. devices are identical, I'd be able to flash any one carrier's firmware on to any carrier's device, provided there are no inconsistencies with the bootloader versions of the firmwares.
The phone is intended for an extended family member and I am able to purchase a T-Mobile GS7 Edge for significantly cheaper than from any other carrier. Because it will be used on AT&T's network, I wanted to make sure I got everything right before I get started. I either want to flash the AT&T version which will allow it to be fully compatible on the network, or the Unlocked version. Apparently, the unlocked version is completely debloated since it's not associated with any carrier and provides better benchmarks, especially battery life, so I'm interested in that.
I've compiled the resources I need in the following:

etc.
One question I have is whether I am able to flash the Unlocked firmware at all. I don't currently have the device in hand so I can't check the baseband version, but my understanding is that the Unlocked version is currently on a lower bootloader version whereas it is v4 for AT&T or T.Mobile. This would mean I would be able unable to flash the Unlocked firmware if the device already has a higher version of the bootloader, right? Conversely, I would be able to do so if the T-Mobile bootloader was on the same version as the Unlocked version (e.g., if the device hasn't had an update to its bootloader).. The same issue would arise if I wanted to go back to a carrier firmware. Where can I find a list of T-Mobile firmwares and their bootloader versions so that I can check? Threads I've searched are saying I can't go to 935U from 935A/T because of mismatching bootloaders but others are saying I can go back to 935A/T on Nougat (same bootloader versions?) so clarification would be greatly appreciated.
Edit: Just discovered the bootloader version can be determined by looking at the 9th character in the baseband version. Pretty simple!
Another question I have is whether flashing the AT&T firmware will give me VoLTE, Wifi Calling, tethering, etc. on AT&T's network. I've established that if I flashed the Unlocked firmware, I'll lose these functions (unless I root the phone, but that's a no-go since I need Samsung Pay intact). Just wanted to make sure that I would retain these features if I flashed the AT&T firmware on the T-Mobile device. Also, would I receive all OTAs pushed from AT&T while I'm on their firmware, even though it was a T-Mobile device? Or would I have to manually update it somehow?
Many thanks in advance.
Yes you can flash the unlocked firmware, I do recommend flashing the at&t CP (radio) though for better signal.
For tmobile all we lose is video calling, we retain everything else. I can't answer your other questions since I have not used this phone from tmobile on at&t. I have used the at&t model on tmobile with U and had no issues.

^^^^^this man is correct. Also, is the device you want to flash Carrier unlocked? Even though youre flashing a different carriers firmware or even the U firmware I believe the IMEI still needs to be unlocked from the original carrier. Obviously just pop the at&t sim card in the t mobile phone to see if its unlocked. hope this helps.

flashing the at&t firmware will just be like having an original at&t s7 edge so yes. The Unlocked firmware will be lighter with no video calling(no carrier apps, no carrier boot animation, some of the quick toggles will be different) you will retain VOLTE HD calling, wifi calling(if at&t has that) and with the at&t you will have all the bloat (about 2-3 GB of used storage plus more a tad bit more use on ram usage) which will use more battery. remember like stated above, if you do decide to flash the U firmware, make sure you flash the latest At&t CP being you will have better coverage since youll be on the at&t network.

I Flashed an AT&T S7 Edge with T-Mobile firmware and:
1) Status remains unmodified
2) Android pay works (as well as Samsung pay)
3) I've already got 2 T-Mobile pushed firmware updates that installed without any issues.
Don't know if this helps, but I'd think it would be the same going from T-Mobile to AT&T.
I did also have to use a modified version of "ODIN" and flash a "PIT" file because T-Mobile has a different partition than AT&T.

Am I doing everything right?
Should I just flash all U files (including Radio) and flash ATT Radio later?
Please advise

All US variants can flash the firmware interchangeably. Just download the corresponding firmware and flash everything(Except for the modem if you'd want to keep the original modem). You dont need anything special. If the default odin dont work, then try the comey "cracked" version.

Why is it that we use the CP for AT&T; however, use the Unlocked CP for TMobile? Are the radios the same for the unlocked and T-Mobile variants? Where would I get this information if I needed it in the future?
I have a GS7 edge locked to T-Mobile with the Device Unlock app. Will flashing G9350U firmware unlock my device and bypass the Device Unlock app or will I still need to use this app to unlock?
Radios are different. I flashed ATT Radio after I flashed U firmware. Though honestly I cannot tell the difference

I did also have to use a modified version of "ODIN" and flash a "PIT" file because T-Mobile has a different partition than AT&T.

What pit file did you flash? Did you flash the the pit file Odin pulls from your phone? Did you flash an att specific pit file?
