G935P bricked with AT&T ROM

Hello,
I've a Galaxy S7 G935P from Sprint and accidentally was installed a different rom (the G935A rom including kernel, modem, and other, from AT&T) instead the most recent android for G935P.
I can access to download mode (and now this mode show the S7 Edge model as G935A instead G935P) but I can't install again the G935P software through Odin, I tried several times and nothing, also if I try to install a G935A I get an error and fail to upload the system.
I was reading other threads but they have problem with T-Mobile and AT&T, does anyone knows a way to recover the Sprint phone and install the original software?
Can be installed TWRP to solve the problem deleting all the system, data, cache and install a rom from TWRP recovery?
PS. I don't have warranty because the phone was rooted to unlock it.

Its worth a shot to try to flash the latest g935u rom. As far as i understand, it is a universal rom that is the same across all carriers.

you are bricked.
only hope is samsung warranty.
take it to your carrier's store and tell them your phone isn't working.
they will either replace it on the spot or give you a phone to borrow and order you a new one from samsung.
if you bought it off ebay or retail you are fuct.

I don't have warranty as mentioned above, so I can't replace the phone. I guess there is a method to unbrick the S7 Edge or something because I can use a special rom for tests (I can't see the samsung interface, but I can see the signal, touch, microsd and other) but I don't want to test without knowing, to avoid hardbrick or something.... maybe someone comments a method to solve it.

There is still hope.
Many of these phone store (sprint, tmobile, att, etc) have a samsung rep that comes by and promotes products.
Find one of these reps and he will help you.

I am a Market manager for Samsung Electronics America and I'l be honest with you, we are just going to recommend you to contact 1-800-SAM-SUNG and talk to ECR and give them our employee ID and say we already troubleshot and we recommended sending it in. Ask for a 1-day air shipping label.

I just want to let you know I fixed the phone using odin by Prince C. I installed G935P without problem and I tested G935 (now it works and has a better battery life) but I reversed to G935P. Thank you for all

He probably had the newest sprint version qj3 and tried to Odin the at&t version. Sprint updated the bootloader, so other firmware won't work until they are updated as well. Right now, sprint is on v5 and everyone else is v4... that's why it didn't work.

Yep. Error after reboot in recovery would have mentioned that Fuse 4 was invalid or something to that effect. Use the QJ1 ROM and should be good.

Update SM-G935FD Dual Sim to Android 7 ?

I bought this phone from the USA about year and a half and I'm using it in Macedonia, Europe the whole time. It is a dual sim, but I'm not sure which country it is exactly from, Taiwan maybe I guess?
The model is SM-G935FD and the Baseband version shows: G935FXXU1APB6.
I tried updating it manually, but always says you're using the latest software version even though android 7 has came out a long time ago.
Can you tell me:
1. How can I update to android 7 ?
2. Why am I not receiving an update automatically, even though this feature was working when I bought the phone. I was getting regular updates automatically ever since I bought the phone up unti a point when the 7 came out.
3. If I update the firmware through an SD card or whatever method you suggest its best, will I continue receiving regular updates automatically after I install the v7.0 ?
4. How can I check what country is this phone from?
Lots of questions, would be glad if someone can clear these things up for me so I can understand better how this works with samsung and different countries models etc.
Thanks up front!

try smart switch on PC to update it... frend of mine had s7 flat and no update via mobile phone, as soon as I connected it to pc and turned on smart switch update came out...

I wanted to mention that, but I've probably forgot. I did try Smart Switch, but it also said, latest update already installed. Any other ideas?

I'm sorry for my noobish questions, but can you please explain to me how to choose the country of my firmware? Do I need to choose a country which I currently reside in? Or do I need to choose a country for which the phone was made? I just want to use English language, even though I use it in Macedonia, Europe.
Please kindly advise. Thanks!

1. How can I update to android 7 ?
i had the exact same problem as you smart switch n ota both said i was on latest software. All you need to do is goto sammmobile download firmware for your s7 edge model if your phone is non carrier or unlocked then you can download any carrier version. after that download Odin n Samsung drivers n view an odin flashing tutorial on YouTube.
3. If I update the firmware through an SD card or whatever method you suggest its best, will I continue receiving regular updates automatically after I install the v7.0 ?
I am getting all the 7.0 updates.
4. How can I check what country is this phone from?
if i remember correctly Its written on the smartphone box although u don't need to worry about the country all you need to know is the model number.
But to tell the truth there is no performance difference only ui change but still if u want to be on the latest version then use Odin. good luck.
I have flashed my s7 edge about a dozen times n haven't faced any flashing problem just be sure to use original cable n try not to use the computer while the flashing is happening. use odin in adminstrator mode n if possible kill extra background processes like chrome etc (not needed but i still do it just to be safe)

Just checked my phone with PHONE INFO app and there seems to be no CSC code?! All these field are empty:
Original CSC Code: blank
Firmware CSC Code: blank
Active CSC Code: blank
Available CSC Codes: blank
CSC Country: blank
I tried dialing *#1234# and it says:
"USSD code running"
but it shows some kind of error right after:
"connection problem or invalid mmi code"
and does not enter the menu with the CSC code. Tried restarting the phone, switching sim cards and what not.. Nothing worked and I have no clue what my CSC code is now.
My original box is gone and can't really see what country it was made for, but as far as I can remember it didn't say anything on the box. The title of the original amazon.com listing says: Internationally Sourced (Middle East/Africa/Asia) Version G935FD which doesn't say much.
I don't know what to do, I'm a bit scared to flash it with just about any country firmware. There's got to be a way to find more about this phoe CSC?

Download cpuz app from play store. From the app you will find what is your phone chipset. If it is exynos download any 935fd nougat firmware and flash it with Odin.basically 935fd is a unlock version. it's support all csc version and you will also get update how much I know.

At&t galaxy s8 update problem.

Hello guys..
I bought an unlocked AT&T S8 SM-G950U and the biggest problem i am facing now is with software update, my device is unable to fetch any updates from at&t.
I contacted At&t support and they in order to receive updates you got to have a at&t connection or else you'll not receive any updates. No manually dowloadable updates are also not avilable. They suggest to contact samsung service center.
My bootloader is also locked as its an Snapdragon US variant, please can anyone tell me that i can flash samsung stock rom on my s8 or not?? and how to do it? Or any other say to download at&t update?

If you have an unlocked S8, then update will come from Samsung directly and not AT&T. Do you really need AT&T's updates?
1) When you check for update, what do you get?
2) Also what is the build # that your phone has at the moment?

Go to the at&t S8 forums. Firmwares and instructions are posted there. I even linked to the latest Odin firmware if you search my posts.

Yes, you are able to flash unlocked Samsung firmware on your device. Read this and ask questions on that tread:
https://forum.xda-developers.com/galaxy-s8/how-to/snap-guide-flashing-standard-fw-carrier-t3625817
I believe you should be fine by doing flashing from section 1: Standard flashing.

All firmwares for G950U are here. Some are branded some are unlocked. Choose the unlocked one. Do you need full steps?

Thanks for replying.
Yeah sure it'll be really helpful. If ull guide me out.

Facing the same problem, did you find a solution parkarintl?

Download the G950U1 firmware and install it. Should have all the features, no bloat, and faster updates.

Go to Updato.com and search for firmware for G950U1. Download the fw for the XAA variant. Extract all the files, remove .md5 off the end of all the files, flash them with modded Odin. You'll be on fully unlocked firmware and you'll receive future carrier free unlocked updates.
Latest fw: (QH3)

Hi,
Now on the phone:
Model : SM-G955FD
Buildnumber: NRD90M.G955FXXU1AQ19
But it is a S8 Plus with only 1 sim
thnx

That makes no sense?
The SM-G955FD and SM-G955F use the same firmware.
The only way that would happen is if you flashed a SM-955FD specific firmware. it won't cause any problem or affect your device in any way.
But it would help to know exactly what you did while you "were playing" in Odin.
If you tell us which country or carrier you are with, we can find the correct firmware for your device and you can flash that back and it'll be back to how it should be, if you really want to get it back to normal.

How to make my unbranded Samsung Galaxy S8 work on ATT again. Pls help!

Amin, Rajan - GCIB NY​

to me
I have an unlocked/unbranded Galaxy S8 (SM-G950U1; Baseband is G950U1UE8DUG4). I was using it on ATT but now it doesn’t work after ATT 3G upgrade. I have read that I can flash G950U firmware to my U1 phone and it will work on ATT.
Is it any G950U firmware or do I need a specific version for ATT and my region? Can you show me where to find the needed firmware?
Can someone walk me through steps on how to install the firmware (including where to find Odin and any other downloads I need).
If this will wipe my phone, is there anyway to back up my phone so that I can get all my contacts, text history, whatsapps history, apps back on the phone after flashing it? Can you also walk me through how to do this?
Will this actually work even though my IMEI is staying the same – ie even if I change the firmware, wont ATT know that the phone was not originally an ATT branded phone and thus it wont work no matter what I do?
Lastly, the only reason I am doing this is bc I really like my Galaxy s8. But the S8 only goes up to Android 9. What are some of the issues I could get using phone that only goes to Android 9? (For example, could it be that I wont be able to download new apps if they are programed for Android 10 and above)?
Im a total newbie to this. I hadn’t even heard of Odin until yesterday so please make the explanations for someone is not a tech person.

At selected Best Buys the Samsung Experience center can flash it for you.
I don't flash my Notes... as I don't wish to potentially contribute to the bricked phone threads here.
At least not yet.
