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.

Serious help needed for s7 edge. Calling all the senior developers and members.

I have an s7 edge (G935W8) which is from canada. I am using it in india right now. I want to get volte working on my device which from searches i've found that i need to have indian firmware installed on my phone.
So i tried several firmwares, MM and N also, but no luck with odin. It is giving errors straight away ( repartition operation failed and oltht). Tried different firmwares, only ap and csc, repartition ticked and unticked and all the stuff that i've founded on the internet.
I don't want to root, i want only official Indian firmware on my S7 EDGE from CANADA (SM-G935W8).
Please guys help me out with that. I want it done.

Yes, you can get back to the stock firmware from custom ROM. All of the stock firmwares/os are here: https://www.sammobile.com/firmwares/ and can be flashed with odin, resetting the phone to factory default state, i.e. as you buy it now and without any info on it. No matter if it was custom ROM or not before that.

Depends on the model. If on the site there is canadian firmware for that model of the s7 - can be done via odin. If the phone is specific and there is no canadian firmware - can't be done.

Odin Flashing?

I was able to get my hands on the U.S. non carrier firmware for the G950U. The question is, without OEM unlock option, will it successfully flashed via Odin? Has anyone already tried? If so, what was the result?

can you share this firmware ?

Yes. I have the same version. Not having the oem is like having it ticked on. So you are good to go. Would love to get my hands on that firmware so I can start testing. I also need G955U. Any chance of a link or mention of where you got it?

I can upload and post link, which may take awhile, or you can use SamFirm ( https://forum.xda-developers.com/galaxy-tab-s/general/tool-samfirm-samsung-firmware-t2988647 ), which is the same program I used to download the odin firmware. I cheated by using SamMobile to confirm CSC code to input into SamFirm and the program will download the odin file and decrypt it to allow for extraction.
For instance, I downloaded SM-G950U/TMK Firmware, which is the USA variant, but, in theory, lacks the TMB system bloatware.
But to get an update to my attempt to Odin De-bloat my S8, I have a suspicion that USERDATA no longer lives within AP, instead it has its own Partition within the Full Odin Firmware, thus, meaning that simply flashing AP, BL, and CP from a Non-US Carrier firmware will NOT remove the carrier system bloatware. Until there is a Odin build released that allows for flashing the USERDATA.tar.md5, the TMB bloat remains after flashing the Generic Odin firmware. But you guys are more than willing to try a find a way to flash the firmware to change the CSC code from TMB to TMK, USC, or whomever does not load carrier bloat into their build.

Thanks for the heads up!

Whilst your post is is informative, I hope you will excuse me being a little pedantic, if the phone is "hard bricked" it can't be fixed and conversely if it cab be fixed then generally that would be considered "soft bricked".

So far it CAN'T be fixed, so for now consider it a hard brick.
And stop arguing semantics when we are trying to actually help people and warn them before they brick their phones.

So does it apply to the international model too? If I get a G955F from Germany and flash a XEU firmware, it will brick?

I Have a doubt here. I am in a unlocked tmobile firmware on oreo beta. I was planning to flash unlocked firmware to it. so my question is
1) If i flashed unlocked US firmware G955U1 to G955U now, will it hardbrick after BLv3 update.
2)If i flashed now and updated to Blv3 after G955U1 will it be stuck to that firmware forever?
Thanks

xdanilva said:
This applies to all American/Snapdragon and Exynos S8, S8+ and Note 8 models once BLv3 comes out for those models.
If you flashed a out of region firmware such as G955W, G955F, G955FD etc.
Flash back to your original model firmware or you'll be hard bricked. I'll post updates about the hard brick part. There's some news developing about how to fix the hard brick.

1.) Yes
2.) You would get a non standard hardbrick. You would be stuck in Emergency Download Mode. You can't flash back to g955u even with standard Odin.

Another question please.
I have 955FD model and i have flashed DBT 955F firmware.
As i can see in sammobile there is 955FD firmware and it's the same as 955F.
I will be ok or not?
Στάλθηκε από το SM-G955F μου χρησιμοποιώντας Tapatalk

Does this only affect U.S. models or will this affect all models? Also, does this mean there will be no more rooting these devices or can you still root them as long as your phone didn't originally have v3? I.e., the modders can still build versions of the new modified firmware with v3 replaced with the old one? Or will those of us who want to keep our root have to just never ever update (through flashing)?

I'm sorry... this means we can't install custom firmware after this ? what i can do now to prevent this ? i have 955FD and not installed custom firmware or root yet... i want to be able to install custom firmware ... what can i do ?

Seems that Samsung reads XDA as well.... Targeted "security patch"... ?
Sent from my SM-G955W ??

What could be the reasons for anyone to flash another region firmware / ROM? Just curious.
Anyway im safe because i use G955F ROMs (my device is G955F) from the beginning and plan to do so in future, right?

Search for the Oreo Odin update on Google that was released for India a week back but it is no longer available as Sam took it down. Otherwise, flash the last Nougat version. Yes, you'll loose root, twrp etc as the phone would return to the stock condition. I could have recommended flashing files through twrp, but I believe, your active CSC is messed up so a clean flash is highly recommended.

You're doing something wrong. The active CSC can't be BTU if you followed the steps correctly. Till the time, you don't completely wipe the device, it would never fall back to the correct CSC. Additionally, you need to have an Indian sim in Slot 1 before you do the process as system dynamically allocates the CSC based on the sim in slot 1.

In the firmware pckg, there are 2 CSC files, one is the regular CSC that completely (System,Data,Internal Storage) wipes the device and the other one is Home_CSC that wipes all except the Internal Storage. You need to use the regular CSC.
Else, right now go into Settings >> Reset and do a Factory Reset.
