Flash T-Mobile S7 ROM on AT&T S7 - Samsung Galaxy S7 Questions and Answers

Hey XDA,
I just recently purchased a AT&T S7 (SM-G930A). I also just recently found out that AT&T doesn't push updates to non AT&T network phones. I am using the phone with T-Mobile and I was wondering if it was possible to flash the T-Mobile stock rom without tripping Knox or anything of that sort. I remember being able to do this to my AT&T Note 2 back in the day. If it is possible, can someone kindly link me to the file and instructions on how to flash the stock ROM from T-Mobile? Thanks!

Nope, as of now there are no de-bloated firmwares available for the US versions.

I do have a G930P and I did flash it with a G930U FW which doesn´t have any company bloatware, phone works better than before, mine was unlocked since I bought it and I'm using it with a Mexico SIM with no problems.
Please check this post in the S7 AT&T section:

Verizon S6 running G920VVRS4CPL3

I recently switched my S6 from Verizon to T-Mobile. Can I flash the T-Mobile firmware on this phone?

In short no. The closest to what your thinking is like having a s7edge and instead of running your providers firmware, in your case (T-Mobile) but you got a Verizon phone, you could download and run the "unlocked firmware" for the phone. In this example it'd be SM-G935U if say you had a SM-G935R4(U.S. Cellular), I know you can also flash other providers to the s7edge like verizon to a us cellular phone. Don't think it flys with the s6 like that though.
That's what I kind of figured. Verizon has their phones extremely locked down but figured I would ask before I tried and bricked it. Thanks for the imput and help.

Switching Verizon S8+ to Tmobile

Hey guys so i got the verizon s8+ and i was wondering if i flashed
Galaxy S8+ SM-G955U 07.06.2017 7.0 USA (T-Mobile) (TMB) G955USQU1AQEF
Galaxy S8+ SM-G955U 01.05.2017 7.0 USA (T-Mobile) (TMB) G955USQU1AQDE
would i be able to get WIFI CALLING, HD CALLING, BAND 12 working by just flashing this? i dont care about bloatware.
I saw a thread about switching to carriers however you need ENGBOOT, FACTORY BINARY, 955W firmware and stock and modified odin.
however the issues with this is i dont understand what this engboot and factory binary are and why i would need them. I also do not know where to get those and the stock odin.
Can anybody help?

you CANT use att unlocked s8+ on verizon, it only works on GSM carriers. if you want to use verizon, sell the att s8+ and get Verizon s8+
i have unlocked att s8+ when i put in Xfinity mobile simcard which uses verizon towers. my unlocked att s8+ got no signal.
Oreo is out for at&t users anyway, look in the guides section. Apply update from SD. Easy and smooth.

How to flash verizon Galaxy S7 from T-Mobile back to Verizon?

Hi Everyone,
I have a question about flashing my Verizon phone back to its original firmware. I have an sm-g930v. I flashed it to the T-Mobile firmware to get better service on my network. But now im purchasing a Galaxy s9, and I am doing a trade in on the Samsung web site.
I was wondering if I could still flash it back to the original Verizon firmware after flashing it with T-Mobile?
