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.
in this moment my wifi signal does not work, and i need to back to PJ2 cause Android N beta bring me problems with LTE in gsm mode, someone can upload home CSC of PJ2 so I can go back without losing any data ?

If you can acces download mode, you have no problem. Download from sammobile.com or samsung-updates.com an original firmware and flash with odin.

Maybe your partition is broken. Search for am offiial firmware here at xda with PIT file and flash that. Be aware you will lose all your data

What's your carrier?
Okay very simple... you need to flash the stock room for your phone. It has to be the exact model for your phone. You can acess this file from sam mobile. Once downloaded use odin to flash it on to your phone with a computer.

dont panic buddy
first of all :
power off your phone
at the same time push these buttons : power + volume down + home
when blue screen comes out push the volume up button
then it is DOWNLOAD MODE or ODIN MODE right now
so u may be able to use odin v3.10+ to flash the stock rom on your phone without any problem
How did you end up flashing a Moto G4 ROM through Odin?
Odin only accepts tar files, and Moto ROMs usually come zipped and need to be extracted and flashed through fastboot or through TWRP if they're custom ROMs.

That's the real question
Search the right Rom for your country here http://www.sammobile.com/firmwares/database/SM-G935F/
1) Create a account and download the rom
2) Extract the downloaded rom with WinRAR
3) Download Odin and insert the 4 files in the right spot inside Odin
4) Boot phone into download mode, connect it to the pc and click flash

I'm still confused, how could someone actually do that? And then follow up by flashing another incorrect ROM for the flat S7 instead of the S7 edge. And then go on to say that he can't find ANY firmwares for the S7 edge? Really?
Something really shady about this thread.
Says he's on the S7 Edge, but his sig says sent from a flat S930F S7.
If he's 12 (391 posts too), then I'm Donald Trump.
Why would you flash a Moto G ROM on your S7E? Surely it doesn't take too much realisation to know that it wasn't going to end well? Just flash the .pit file if you can still access download mode. If you can't, then a service centre will be the only way.

Very easy to fix. You'll need to flash the stock rom for that phone using odin. Get the stock rom from from samobile and there are many tutorials online
The problem is the kid kept flashing random rom. Please make sure the correct rom. Maybe uploading the box's picture would help.

Seems like it.
1. There's no way to flash non Samsung firmware through odin.
2. No s7 edge firmwares? Really? Updato and sammobile, have all of them.
Sent from my S8 Edge (G945F) using Tapatalk.
Have a question here, we get a lot of US imported phones here in Pakistan, mostly AT&T and Verizon S7 edge phones.
They've got carrier bloat and whatnot, I remember reading people flashing Verizon ROMs to get that to work properly on their AT&T phone and flashing AT&T on a T-Mobile phone to get that to work properly, so if one flashes a G935U firmware on a G935V, is it expected to work fine and act as an ordinary Snapdragon 820 S7 edge with no carrier bloat or anything?
All replies will be appreciated.
Thanks

I tried flashing G930U on my G930V through odin but it failed. It appears that I can't flash anything using odin. The only way by which I was able to install a firmware manually was through stock recovery by Applying update from sd card.

I have, but there have been reports of it not working for some people as well, so I wanted to know if it's a legit method or if it's trial and error and it works for some and it doesn't work for others, because if it does work officially, then it'd solve a huge headache on choosing US variant phones here and we can all relax since the 935U firmware can be flashed on carrier branded phones.
Now, I need to get my hands on an American S7 edge to test this out myself.
Off course without testing nothing can be confirmed ... But most people r too faint hearted to try it

All of them. AP includes the system, recovery and cache, CP includes modem, BL includes bootloader, and CSC includes sales code.
The ROMs for S7 usually come with CSC and HOME_CSC, the latter will not wipe your device and keep the Verizon CSC which may cause issues and require you to factory reset your phone, the normal CSC files wipes the data and switches your CSC to the new one you're trying to flash.
Choose whichever one you want but I'd suggest the normal CSC just to be safe.

The main issue with me was poor battery life which was resolved when I reverted back to marshmallow. But I have yet to test the battery life on nougat. Other than this, phone is running smoothly and it feels light now due to no bloatware.

I used Odin to install the unlocked firmware but I'd like to install the 975U att back. I tried installing the one on that guys post on this forum, it worked but I couldn't update it for some reason so I installed the unlocked firmware back. Maybe I didn't do it right or installed the wrong things idk. Can someone help me? Maybe point me in the direction of a proper installation guide + link. I'd appreciate it
