Flash T-Mobile S7 ROM on AT&T S7

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!

You can, however once you do you can't go back. It may be possible in the future, but Tmobile has a v3 bootloader, and AT&T is still on v2 bootloader.

Thank you! One more question, I have the stock T-Mobile ROM and for the CSC, there are two files:
CSC and HOME_CSC
Which one do I choose in Odin for the CSC option?
Thanks

When attempting to flash using Odin 3.12.3, I get this error in the log:
FAIL! SHA256 is invalid
This seems to be because of a corrupt file?
I downloaded the ROM from two different sources now and still I get the same error.
Thanks

Thank you so much!! This worked!
And I figured ou the difference between HOME_CSC and CSC:
HOME_CSC keeps your data while CSC wipes it
Thanks so much

So TMobile ROM on 930A . Any issues ? Did you try going back to AT&T ROM
All that talk out bootloader versions and not able to restore back to AT&T ROM
Can you odin Unlocked 930U version ?

I'm using Cricket on AT&T S7 variant and I couldn't get any update from AT&T, which pissed me off. So I decided to flash G930U firmware and I succeeded. But unfortunately, there isn't a single G930U update been released so far, which is quite surprising.
Other than the update, I'm extremely satisfied with the new firmware. It's so fast and clean comparing to my previous bloated AT&T firmware, free of all kinds of overheating, battery dropping, slowing down, crashing, auto-restarting, bugs and lags (Just so you know, my G930A firmware was the newest. I had to take my phone to Best Buy to update. And I used PDP to disable bloatwares). I highly recommend everyone to flash G930U. The new firmware also has an APP called Samsung+. It's very useful and it tells you if it detected slow charging, or reminds you to restart your phone if it hasn't been restarted for a while, etc.
I'm still wondering if I can receive OTA after flashing anther variant firmware, but I can't confirm since there's no update for G930U yet. I'm curious to know if OP could receive any T-Mobile update after flashing.

No issues at all so far. Works perfectly. I don't really want to go back to the stock ATT ROM because I don't need it.

I flashed to the latest update of the ROM so I can't prove it works. But from what I've heard, after flashing the ROM you need to factory reset the phone so it can unregister from att and register to whatever carrier you are using it on. I am not sure how true this is but I read it somewhere and it seems to make sense.

if you ever switch ROMs please check about the issue of bootloader version and not able to revert back .
Not able to revert back is the only issue keeping me from odin to T mobile ROM
If bootloader version is a problem then you cannot flash 930U firmware also
Is that so ?

I'm not sure what bootloader the G930U has. The att ROM has v2. If it's newer than that, then downgrading isn't possible. Is its the same, then it should be fine.

I was also able to flash the 930T on my 930A. I saw there was a Note 7 port but you need root and TWRP. Haven't tried flashing back to 930U yet, but thinking about it.

Anyone else get the apk1 update?

Got this update tonight? Anyone know what it includes?

Yes, if you have the Samsung beta app installed look at the notices... They just sent me one with whats been updated.
- My phone is updating at the moment.
Ohhh mine was in reference to the Nougat beta, apologies.

Hmmmm...not too sure then. Yeah I was on pj2 when I first got my edge last week and wanted root. The only way I was able to do it was flashed Verizon fw which I think was pe1 then root and flash echoe rom. But it was way too laggy for me. So right now I'm on unlocked fw ai3. Which has all bloat removed and seems smoother then sprints pj2 stock fw

OK good to know ... Yeah I thought it was package Disabler causing it, but I had re-enabled all packages and ended up just removing the whole app, still not updating. I'll just wait for the tar file!

Deffinately not package disabler pro. I was able to update with all my packages disabled. Although maybe you have apps disabled that i do not have disabled. Nonetheless i have not seen any major improvements at all in the update. So i would not worry about rushing to get it.

Debranding S8

Hi guys, I'm out of USA.
After many failed attempts still can not debrand my AT&T SM-G950U.
Through ODIN I upgraded successfully to latest G950USQS1AQF7_USC
But can not find any unlocked firmware (XAA) to my S8, only for S8+.
Any idea where to find it?
Thanks.

Not searching very hard then. Update.com and search firmwares for G950U1. You'll see the latest XAA listed.
Works great (Minus volte and wifi calling), I've been running it myself

Thanks joe3681 for you answer.
Firmware downloaded from sammobile (G950U1UEU1AQE3_G950U1OYM1AQE3_XAA)
But i got the following error when try to install it: FAIL! Model dismatch fail

Sounds like it's not correct fw then.

Hi Guys, I'm in the same case as the OP, and I have always updated via Odin using Sammobile's firmware, which only includes the AP file. I already downloaded the modded Odin and firmware from joe's post, but it includes a lot more files.
Should I load all the files to Odin? or just flashing the AP file would be OK? Thank you very much in advance!

It's only for carrier S8's. They have no firmware for unlocked models.
You can flash QK5 through Odin and do it that way if you're on a US carrier and want bloat though.

I just updated my phone from that site and it works perfectly thru stocked recovery. They are all OTA updates so it will not wipe your phone. Only thing is when flashing from nougat to oreo change your themes back to pure stock or you will get system ui error, and have to factory reset

Unable to downgrade from U1 unlocked to ATT U firmware

I currently have the U1 unlocked firmware flashed and am trying to flash it back to the original U firmware because of the new bootloader issue. I am receiving an Odin fail error all the time with different USB ports and computers. Is there something I did wrong? Also, I purchased this as a G950U device. I recently got it unlocked through ATT so does that mean it is now a G950U1 device?

The G950U is the unlocked version, so why did you have to unlock it through AT&T?
It should've worked straight off the bat.
This is the U version (For USA, unlocked version) https://www.gsmarena.com/samsung_galaxy_s8-8161.php#g950u
And the AT&T version is the G950A.

Is the bootloader version on the firmware you're trying to flash the same as the one that's on there now? You can't downgrade bootloader versions.

I'm honestly not sure. The firmware was the original stock ATT version and I was running the latest Nougat update. I switched the CSC code back to ATT from AIO this morning using the main guide here, but I am now stuck on that Factory Binary screen. Is there a firmware for v2 bootloader for ATT out there?

Hey joe thanks for this! I figured I'd give it a shot to flash back to unroot and it worked! I also checked my warranty in the download mode and it's still at 0x0 and I'm still able to use Samsung Pay/Secure Folder so I didn't even trip Knox.
