Nope, it won't lock or re-lock your phone, once a phone is unlocked properly it will stay that way
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.
I'm sure I not the only one switching carriers, I have unlocked S7 AT&T SMG930A , android version 6.0.1 on T-mobile network, everything work fine, what are my option to get version 7..
Thanks
Flash with Odin, or attempt to flash tmo fw in Odin.
I bought myself an unlocked AT&T s7 edge (SM-G935A) a while ago and recently flashed it with an SM-G935U firmware. I didn't flash the 935A version cuz I thought it wouldn't work here in Malaysia (somewhere in Asia). After flashing it I had no problems using wifi but couldn't make calls even with a SIM card in it. I have tried flashing the 935FD version but couldn't get it to flash with Odin due to errors. I've even tried to buy an unlock code for the 935A version and that still didn't work. Any ideas?
I'm new here so hi.
modem problem
i had the same issue.
tip *#0011#... see if shows up the imei number and SN... look for CERTI FAIL
if true, just flash your stock rom ( what works normally) and then flash the U version without the CP File.
I have a Verizon SM-G975U with the firmware G975USQS2ASGB, Now i just switched over to T-Mobile and would like the T-Mobile firmware on my device since while I get service, it is not as good as my family members galaxy s10+ from T-Mobile and putting the T-Mobile sim card in when I switched didn't updated my firmware. How do I go about doing this since I am new to firmware flashing. Is sammobile.com a legit site? do I download the firmware there and follow their instructions? I would love it if someone would give me dumbed down instructions on how to do this without bricking my device and preferably not having to do any factory resets but if I have to I will and just restore my smart switch backup, thanks for any help.
There is another thread with flashing instructions. You need to use the modded Odin, not the official version.
I think if you are already on carrier firmware and want to switch your phone to a different carrier firmware you need to flash U1 firmware and convert your phone to carrier free/unlocked before you can convert to the U firmware from a different carrier.
Sammobile is a legit site but there are no guarantees you won't brick your phone when flashing firmware using unnoficial software like the modded Odin.
But the chance of bricking is small as long as you don't flash incompatible firmware. Flashing T-Mobile firmware (with the T-Mobile User Data file) over firmware that is branded for a different carrier will probably brick your phone which is why you need to flash U1 firmware before switching to a different carrier firmware.
I have two carriers, ATT & Verizon,
I have tried the Verizon chip in my unlocked ATT S10+ (SM-G975U) and only time it ever work some what is when I was at the Verizon Store.
Because of that issue I tried to flash it with "ODIN" with the latest firmware that supposed to be for the Unlocked version, after flashing I still see that ATT LOGO & apps on the phone.
One thing I noticed; while it was restoring it choose "HOME_CSC" instead of CSC that I have choose.
ODIN was on Default settings.
Do you have a guide I can follow to flash the S10+?
Are there pre-rooted custom firmware for the S10+?
Thanks
