I recently activated my SM-N910A on my new T-Mobile account. The phone was out of contract, so I asked AT&T to unlock it, and they did. The phone is working properly with my T-Mobile SIM card, albeit on the AT&T firmware.
Is it possible to replace the AT&T firmware with a stock Samsung Firmware, or, at the very least, with the T-Mobile branded firmware (for SM-N910T)? I understand that the bootloader is locked on these AT&T devices. Is it possible to unlock the bootloader and load a different firmware onto the device?
AT&T firmware has SO much bloatware, and I've not had any luck finding a way to root the phone on this firmware, so I'm stuck with all that bloat. What are my options here? Thanks!
EDIT: The phone was updated OTA to Marshmallow (6.0.1) when it was on the AT&T network. Build number is MMB29M.N910AUCS2EPH7
My mum went to the US and Mexico from Australia last year for my brother's wedding and a holiday. She bought an unlocked T-Mobile Galaxy S5 and prepaid T-Mobile SIM to use over there.
However now she's back in Australia there are a few issues with the phone such as the T-Mobile bloatware and US defaults on the phone.
I thought it might be possible to flash an Australian variant of the stock firmware from the SM-G900I and searched for instructions and thought I'd figured out how to do it with Odin only to get a Secure Check Fail: aboot error message.
Some research I've done suggests the problem is with the baseband of the firmware I found:
G900IDVU1CQB1_G900IXSA1CQB1_G900IDVU1CQB1_HOME.tar.md5
Apparently the baseband of my mum's phone is: G900TUVU1GQC2
I was hoping to flash an alternative stock rom without rooting the phone and tripping Knox since it's still within warranty.
Any help/tips much appreciated.
First of all you should never flash different software on to phones they don't belong to it would more likely brick it bt if your phone is TMobile you can easily not root it by going into the developer setting and hitting oem unlock so that unlocks the bootloaders​ from there you can you can use odin to flash TWRP (a custom recovery) and then easily root it and then flash debloat scripts made from devs on this website to get rid of bloatware
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 swear I am not stupid, I realize this sounds insane, but originally my S7 Edge had the model number: SM-G935V.
I soft-bricked the phone trying to get the safestrap feature and when I went into the download after bricking it, it had the model number: SM-G935A. I tried multiple times to flash a stock verizon rom, but it wouldn't work. When I saw the model number I decided to try the AT&T firmware on a whim... and it worked
I don't understand how this happened, I feel like the MD5 file I used had a problem with it, or it was not made for verizon (but instead AT&T) but i desperately need to fix this. What do I do?
AT&T has a newer bootloader than Verizon, so... you can't go back. Not until Verizon releases a firmware with the same bootloader version.
Install BRA1 Verizon s7 edge image with Odin, Prince comsy version.

I think I might want to install the G935U (AT&T) firmware on my Verizon Galaxy S7 Edge G935V currently with Android 8.0
I have downloaded ODIN, Samsung S7 Edge drivers, and G935U (July 24,2018) AT&T version.
Is there any reason I can't do this to my G935V? I am confused on the Boot Loader issues and how they apply
with firmware changes for example when changing a G935V to a AT&T G935U.
I also would like to know if all features continue you work and are there any features you loose.
I have the G935V switched from CDMA to GSM and added a APN config for my Straight Talk AT&T sim.
It works but I don't have LTE band 17 which is used in my area. I barely get coverage on Band 2 in my area.
Thanks,
Ken
The Oreo firmware is out here:
https://www.sammobile.com/firmwares/galaxy-s7-edge/SM-G935U/
I read that I can install the firmeware of sm-935U in my sm-935V, but when i enter in sammobile page ,there is a huge list of 935U firmeware, wich of those do i have to select to work fine in my phone
So I switched to T-Mobile from ATT. I kept my unlocked S7 but didnt realize I would lose WI-Fi Calling which is a must because I get pretty bad service.
Does anyone have the files and steps to flash T software via Odin?
I have:
G930A 7.0
Baseband: G930AUCU4BQF3
