Flash Android 7.0 T-Mobile S7 ROM on AT&T S7 - AT&T Samsung Galaxy S7 Questions & Answers

Hello,
I currently have an unlocked G930A that is running on 7.0, I am using the T-Mobile carrier and I would like to flash to the T-Mobile rom. I know it was possible on marshmallow but I couldn't find any posts regarding 7.0.
If I follow these instructions

Thanks bro! You know which version of Odin to use? I'm on 3.12.3 and it's giving me invalid sha md5 error. File is fine. Other guy mentioned Odin from Verizon thread. Couldn't find it
Edit: Found it! It's PrinceComsy Odin 3.12. It worked perfectly! However, now my fingerprint sensor doesn't work. Is that because I didn't flash bootloader? If I flash just bootloader, will it still wipe the system?
Edit 2: Goddamnit Samsung Pay isn't working either. Says I made unauthorized modifications.
Final Edit: So apparently you have to flash Bootloader as well to get Samsung Pay and fingerprint sensor to work.
Basically, Download PrinceComsy's 3.12 Odin from Verizon Root thread. Then flash the latest G930T ROM from SamMobile. Tick BL, AP, CP, AND CSC. Make sure you ran Odin with admin privileges. It'll wipe internal SD so back that up.

Questions about debloating/updating the AT&T S7

I have a sim-unlocked AT&T S7 phone that I have running wonderfully with my T-Mobile sim, no problems there.
My questions
1) I'm on the February build is there a way to update manually since About Phone > Update is saying my phone is up to date.
2) Other than package disabler, is there a way to flash a 'clean' version of the firmware? Without the AT&T bloat, or is the package disabler the best way to go?

You can ODIN flash the latest firmware to update (will lose data) .
Then you can root , and flash the U firmware over it and it will be unrooted , Samsung Pay and everything working , stock and all - debloated essentially .

Is it possible to ODIN flash the stock T-Mobile ROM on the AT&T S7?

Just Odin the U firmware on. You don't have to Odin, root and Odin. That's senseless.

S7 Edge Firmware Update (G935FD w/ XSG CSC)

Dear all,
Yesterday, I purchased my first ever android phone (coming from iphone 6s) and this phone is such a beauty. Anyway, I rooted it using cfc autoroot and have a question regarding firmware updates: I used SamFirm software and input SM-G935F (F and FD same versions? can't find FD firmwares) and XSG got this:

Is this the right file to use for updating my phone? I guess I am using Flashfire for updating without losing root? I want to keep the CSC and any other relevant config the same because I will be using this phone in the middle east.
I would appreciate you guys input on whether I should go ahead and also a good tutorial for updating without losing root.
Thank you!

Hey there! G935F is single sim version while G935FD is dual sim version. Seems you have got a single sim. F versions will work for you.
Regarding root. When you flash a new firmware file then you will lose root but that's okay you can again root it again. Just like u did first time.
I would suggest you to go with Odin to flash a file.
you can find the tutorial here:

Thank you for the quick reply @iamansar, I in fact have the Duo version. Will the file suggested by SamFirm work for my phone? (not mess up the dual sim, keep CSC as XSG?). Also regarding updating without losing root, I believe you are suggesting to flash FW using odin then redo the TWRP and Su steps?
Thank you!

I apologise, I didn't see that you mentioned that yours is G935FD w/ XSG.
It seems you can flash G935F file to FD phone and the firmware will recognise it as dual sim and you will get those features.
About root, well I must say I haven't tried rooting my S7 Edge yet at least till its covered under warranty.One thing for sure if while flashing stock firmware, you lose root privileges and you will have to root again.
You can use this latest firmware.
http://www.sammobile.com/firmwares/download/82152/G935FXXS1APG3_G935FOJV1APF1_XSG
Have you tried connecting your phone with smart switch in you PC/Laptop with Windows/Mac? As you don't plan on flashing some other country firmware, I would suggest you can go ahead update you phone from there. This what I did today, Mine is XSG as well.

Thank you for the link. I have not tried doing so since my phone is currently rooted and I am afraid trying to update it officaly might mess up my phone. Also, if I flash the file you linked me using Odin, will I lose the TWRP?

Yes! you will. So, Instead of using Odin , It'll be better to flash the firmware using FlashFire as suggested in this tutorial, if you don't want to lose TWRP.

PG1 to PD8 on SM-G930T [Youtube Video]

Just to clarify it is possible to put your S7 to PD8 and technically "downgrade" your firmware . So to go from PG1 to PD8 you just need to flash the PD8 bootloader,AP, and CP in Odin.
*Doing this will wipe all your user data*
As far as I know this only works on SM-G930T !!!!
Please try it out and see if it works on your device.
EDIT: I got a video showcasing the whole process, it's a bit lengthy because i wanted to avoid all cuts in the video due the the suspicion that i may be switching devices ...
https://www.youtube.com/watch?v=G3Fd1s5kOhQ
Well this same thing has been said numerous times before, so do you have proof that it successfully works and also are able to flash other firmware?
As the other user said, if you have proof and can demonstrate how you were able to downgrade, please share with us. As far as I've seen/attempted, this isn't possible because of the bootloader version increment between the new firmware and the older ones.

Have you done this yourself?
AFAIK, downgrading the bootloader isn't possible, as we have already seen in this thread. Please let us know how you were able to accomplish this. Screenshots would be greatly appreciated.

I have done this and will provide screenshots.
Please disregard the G935 version ... I am also running Echoe Rom ... I flashed PG1 Cp,Bl, and Ap . I set it up then I flashed PD8 Cp,Bl and Ap with Odin again ... it was successful no errors. Just to make sure I tried also flashing PB8 but that didn't not work and gave me an error. So I reflashed PD8 and installed Echoe Rom and that is currently where my phone stands. please try it out I need to confirm it works on other devices. I think it works because the PG1 bl is the same version as the PD8 bl. But I can't confirm this. If you tried leave your feedback!

I tried to go from PG1 to PB8 and it didnt work so i tried from PD8 to PB8 but that also didn't work... It seems that it is only possible to go from PG1 to PD8
What is the benefit of downgrading to PD8? Can we flash the 930U firmware after this or it still keeps our bootloader on version 2?

I don't know own which variant the 930U is but There isn't really a benefit besides people saying that PD8 runs better than PG1 or vice versa.

SHA256 Invalid error when flashing unlocked firmware to unlocked S8

Hello,
I flashed my factory unlocked Samsung Galaxy S8 with the Verizon carrier firmware awhile back in order to gain some carrier features. Since then I have gotten a new device and want to flash my S8 back to the unlocked firmware. Flashing to the Verizon firmware was uneventful, but trying to flash it back to the factory unlocked XAA U1 firmware always results in a SHA256 Invalid error right after I click Start in Odin. I've tried the Prince Comsy version as suggested on a few threads, but it just gives a failed to write error. I have also tried another firmware version download (from Updato), different versions of Odin, and different PCs.
Any help would be greatly appreciated.
Thanks.

Anyone?
Still haven’t been able to find a fix for this. Tried with a patched version of Odin to bypass the SHA256 check, but it’s giving me a different error. I’ve attached photos of the exact error messages below. Surely someone here knows something about this?
download latest firmware
its maybe because you are flashing old file with v1 bootloader

Well, you were pretty close. For anyone who is interested, the issue I’ve discovered is that the current Verizon firmware has bootloader v4 on it, and the latest U1 firmware only goes up to bootloader v3. Looks like I’ll just have to wait it out.

Yes, I was getting that error because the unlocked firmware I was trying to flash had an older boot loader than the Verizon firmware that was on the phone. Had to wait until an updated version of the unlocked firmware was uploaded.

I don’t quite remember, I sold that phone soon afterwards. It has something to do with the name of the firmware, I’m sure Google could help you there.

Flashing SM-G935U ATT Firmware onto AT&T S7 Edge with Oreo

Hi,
I am trying to flash my SM-G935A AT&T S7 Edge (not carrier unlocked) with the new SM-G935U firmware (G935UUES4CRG3/G935UOYM4CRG3/G935UUES4CRG3/G935UUES4CRG3) that I dowloaded for my US AT&T S7 Edge. I upgraded my S7 Edge to the latest Oreo firmware via OTA around a month ago.
I used SamFirm to download the image to flash. Anyhow, even though I put every file into its respective category on Odin 3.13.1, I get an "SHA256" mismatch error. I've seen some instruction that say to only add the AP file onto Odin and others say to use the prince cosmey version of Odin. What could be the problem? Does the phone need to be carrier unlocked? Is my firmware too new or of the same version? Do I need to use the prince cosmey version? Is it not possible to flash the g935u firmware onto a g935a phone? Should I use another download source? Should I use the slightly older G2 firmware? Anything else I should consider?
Also, I noticed that I could not download firmware for the SM-G935A using the ATT code with SamFirm? Any reason as to why?
I realize that there are many other threads that touch upon this problem but they are either with a different edition of the phone, firmware version or some other variant. I'm posting a new thread because I want to be as thorough as possible and make sure not to brick my phone by receiving safe advice before moving forward. Thank you for your time!
Below are the SamFirm download details:

Did I post in the wrong thread or something? Is that why there is no response? Would someone be kind enought to point me in the right direction if this isn't the right section for such a question?
Thank You
Hi did you find any answers to this issue? i got stuck on same point as you...
Stock Odin checks the version on the device and fails because the U version doesn't match the A version you are "upgrading". There are patched versions of Odin that skip this check, and that is what you need to do a cross-carrier upload.

Use a patched odin to flash the firmware, it will go through.
