S8 Plus (955f Snapdragon) how to reset to stock - Samsung Galaxy S8+ Questions & Answers

Hello All,
After rooting and installing a rom i now dont have a working modem, i attempted to reflash the stock rom using odin but each time it fails to write when using the AP. i have managed to update the modem with odin but did not work.
I believe i may be using the wrong stock firmware files. could anyone help me please to locate the stock firmware? sammobile doesnt seem to be able to let you download firmware for free anymore?
Its an unlocked device but i had it through EE so i believe this is the file i need? can you please help

Odin flash failed, device 3, binary 2. Help needed!

Hi,
I have a G920F, I was rooted and want to go to stock again. I have restored the device with Smart Switch, but now I am unable to flash any other rom. I have downloaded 3 different roms from Sammobile and get sw. check failed device 3 binary 2 at everyone. The current rom is form Italy Wind the latest OI9. Any suggestions?
Thanks in advance.
Hi, probably you trying to install oldest firmware 5.0.1, download the latest firmware and try again. You are with 5.1, right? This error on odin happens, because you cannot downgrade the firmware. Hope this helps.
I think you can not downgrade even if it is the same Android version.
If it detects you are on a newer bootloader it will give you that error.
What I belive you can do is to extract the bootloader (sboot) and modem from the .tar file and flash ONLY the system through Odin.
Don't know exactly how to do that because I haven't done it but I think that would do; you will have to search and read my friend.
You will have the stock firmware but with latest bootloader and modem.
Hope this helps.
Note: As far as I know this will work if its the same Andorid version; you can not have Android 5.0.2 with 5.1.1 bootloader.

Hi,
I have tried what you said, but no succes. The firmware was already recovered with smart switch so the bootloader is the latest.

Galaxy S7 SM-G930A Android V6 G930AUCS4API2

Hi! I have flashed and engineer boot file to my S7 and it is stuck in a boot loop. I am having trouble finding the stock firmware to fix the problem. What I have found is not fixing the loop. Does anyone have the stock firmware I can use/buy to fix the problem? Can I use a different version as long as it is an AT&T variant? I cannot risk wiping the phone when i do this procedure.
Thanks!
You can't flash stock firmware without wiping.
Updato.com and sammobile.com have all the stock firmware for all model devices.
You should be able to flash any G930A or G930U firmware, except you won't be able to downgrade (i.e. you can't go from nougat to MM).

Thanks for the reply Beanvee! I'll check Updato.com. I wasn't familiar with this one. Sammobile and Samsung-firmware didn't have this firmware version. Anybody else out there have the firmware for this model?
Thanks

I flashed 7.0 on my S7. Also; it was a 930A I flashed to a 930F. Works excellently. I have Xposed as well. So the firmware can be found here in XDA.

N971N - Korean Firmware to Uk Firmware

I was hoping someone could help me out. I have a Korean firmware Galaxy Note 10, i have scoured through the internet trying to find a solution or a flashable firmware to change it back to the UK firmware, to my recollection they both have the same processor.
I have gone as far as rooting so that it could open some doors in terms of reverting back to the UK firmware. i was wondering if anyone could help.
Everytime i tried flashing the UK firmware using Odin it would say the bootloader is locked, however i did unlock the bootloader before attempting to flash the firmware.
Maybe the UK firmware you trynna install is older than the one you already have? Maybe it's preventing flash for such Security reasons?
Tried flashing bootloader only?
Firmware without bootloader?

would you know where i would be able to obtain the firmware?
You can't install Uk firmware onto n976n, this model has only 4 CSC available and all of them Korean.
