I tried to root my S7 Edge about 3 days ago when something went wrong and something got corrupted. Most of stock firmware was missing after installation from looking at files inside of TWRP. Long story short, I cannot flash stock ROM back onto my S7 Edge. I keep getting complete(write) operation failed inside of Odin when I flash stock ROM onto it. The only thing that I managed to successfully flash back was stock recovery and CP but I ended up flashing back to TWRP. Flashing stock BL gives me errors regarding sboot.img.
My phone is not bricked as TWRP works fine and I managed to flash DotOS onto it as a test and it worked fine and I had no issues flashing DotOS onto it either.
My S7 Edge (SM-G935F) is a UK phone locked to O2 updated to Android 8.0.0. I tried two or three stock firmwares from SamMobile under firmwares/galaxy-s7-edge/SM-G935F/O2U/ but I keep getting Odin compeltion failed error.

I updated OTA from 4.4.2 to 5.1.1 and now when trying to downgrade back, I bricked it. I flashed the Downgrade_to_NCE.tar (realizing now that i shouldn't have) which ended in a FAIL in Odin. I tried flashing the firmware, still FAIL. When I flashed the OC4 Stock Partitions, it booted up, but got stuck at Samsung splash screen. Now i have tried all sorts of files, including the OneClick.exe and flashing the full firmware from this thread. still, nothing. I have to go on a trip this weekend and really don't want to have a useless phone.
So I have a galaxys s5 g900f which i cleared it from a rom i used before and got it back to the original form of it. Got the .tar.md5 file of the official galaxy software from sammobile and installed it with odin. After that I wanted to root my phone again and stick with the official software. I tried to do that by the way I always used to with CF-Auto-Root using Odin once more and after downloading the file my phone was normally rebooting to recovery but it actually got stuck there without doing anything. Tried to flash twrp too but still nothing. The only thing i can flash at the time is the official software. Anyone had this issue before and can help? Thanks in advance
Flash the stock ROM again and get your phone back up and working properly
Then use this guide to root / twrp

I recently picked up 2 edges a Verizon and ATT variant, I flashed the Verizon phone succesfully to G935U with this firmware http://i.imgur.com/JuIeA6g.jpg
(The 4-file link in Step 2 https://forum.xda-developers.com/ve...de-flashing-sm-935u-firmware-verizon-t3415145 )
Since that went smoothly I decided to run Odin and flash that firmware onto the ATT Edge, ( original FW is g935aucs4apk1 )
It didn't work, I recall that it got stuck at Setup Connection. So I rebooted the phone and it took me into Recovery mode, where all the CHECKS failed. So the ROM has effectively been wiped; leaving me with just the Recovery menu and DOWNLOAD screens.
Is there any way of getting my self out of this?
Fixed it. Ended up clicking Re-partition and Flash Bootloader in Odin then flashing 4-files from the T-Mobile Nougat firmware using the PrinceComsy 3.12 Odin
Not my ideal way to do this, i'm sure I've lost root potential, but I have a working phone! (w/ No xposed )

Click to expand...

As long as you are still on bootloader 4 (and you are, since to my knowledge there isn't a higher version) you can still root your device and return it to MM if necessary. It may take some effort, but it's doable.
Hello, once flashed the firmware G955FXXU2CRED about Odin habs and now I want to go back. Always had Custom Roms on it. Now I wanted to flash Nougat G955FXXU1AQG5 G955FXXU1AQL5 because of root but it does not work anymore. With this firmware G950FXXU1CRAP everything ran smoothly back to Nougat. Odin Shows Failed Can Anyone Help THANK YOU
