The b and the U and U1 are not the same the u and u1 have the file in bootloader. So, if your reading this and have u series don't flash this is not for our phones but for a b phone.

Quick question. I have a galaxy s7 sm-g930t1 which is the galaxy s7 with metro-pcs. Will this work on this model. It has snapdragon which has a locked bootloader that makes sure its signed. I would assume it would work as long as I also flash the bootloader with this version but I want to be sure.
I ended up just giving it a try and it worked. Thank you!
I'm getting the "sha256 is invalid" error when trying to flash this - I'm using the AT&T Nougat version and want to get my wifi-calling back. Any reason why this may be happening?
odin version
what odin version is recommended to use?

I have the same phone and metro-pcs. After your installation the phone still connects on the metro network?

Yeah it does. The only file I didn't use in Odin was the CSC. I then just went Settings/Mobile Networks/Access Point Names and added my own MetroPCS access point and deleted the rest. Here is my settings and it works great.

No it will not work, this is for Qualcomm variants of the s7 and dpes not support dual sims. It will brick your device

What do you do with the Home_CSC file? I haven't seen this before. Thanks.
Can I flash this to the unlocked US VERSION? I never thought I'd say this but the tmobile version gets updates faster than the unlocked version.
I am receiving an error while i flash it. The error message was along the lines of invalid ext4 and incorrect volume size.

HOME CSC keeps your data, CSC wipes the device, do note that you can only use the HOME CSC if you are are coming from a T-Mobile based firmware

I download from the link. After download I use 7zip to extract. It extracts all files. When I try to extract AP or any other I receive a folder corruption message.

If you use T-Mobile sim card, you always will have T-Mobile firmware no matter what you flash. Now all firmware are base on sim card you are using.

Yeah u right,, even roms without any carriers app gonna be better lol

Call AT&T and ask for unlock code. If your phone is paid off they will give you one for free

Combination File Flashing Issue

Every time I try to flash the combination file for 950U, it fails immediately and throws the "SW REV CHECK FAIL" error.
I'm on latest BQL1 and trying to swap CSC using the method posted here before.
Any suggestions?

When you mention u1 are you referring to the unlocked firm or the baseband.
Edit: U1 is the only combo I can find for 950U.

Does flashing G988U sprint locked phone safe?

I have bought SM-G988U phone which is sprint locked. If i try to flash the phone with the unlocked U1 model would this unlock the phone or not?
Sorry For this but i'm still a beginner and don't know if this would fix my problem. If not, then what would you recommend please?
As far as I know it's safe....but as with anything involving modding your phone....be careful as one misstep could cost you.
Hey dude, I can confirm U1 works great on Sprint devices, currently using it and still getting access to the t-mobile 5g networks here in LA.

No, it will not Sprint device Network unlocked. Your device will still be Sprint locked. I do believe this model will actually fail if you flash in Odin. Sprint pretty much puts an MDM on their devices now preventing firmware flashing. If it does flash by chance, it will just remove Sprint's bloatware apps.

Successfully flashed.
I have a Sprint S20 Ultra. I'm currently on Sprints latest firmware ATE6. I downloaded ATEC which is Junes security update with USC carrier. It is U firmware as well. I am trying to flash in Odin and I keep getting a fail. Any ideas if Sprint has now implemented something to prevent flashing of other carriers firmware? I never had issues with my S10+. This is the first time I am trying to flash firmware with my S20 Ultra. Help please
sigh. all you need is the latest patched odin and you can flash the u1 or other carrier u firmware.
i flashed the att U firmware to xaa U1 firmware. and then flashed to TMB U firmware
dont listen to other people who havent been in the odin game.

patched one
I used the patched 3.13.1 version. Yes it is safe, I'm running the Sprint version UI firmware. Originally tried with 3.14.1 and failed 3x's. Also tried the full International UI firmware unbranded with the 3.13.1 patched firmware and the phone would get stuck on the SAMSUNG logo. My phone is sim locked to Sprint though and that's why I think it wouldn't boot the full unlocked version. The Sprint branded version worked like a charm.
