    HI all, Oky for some detail. I installed twrp on the phone with odin. WHen i started the phone up there were some issues with some apps. I then flashed back to stock rom with odin and now the phone is a mess.

    The phone doesn't boot. It stuck on the Samsung logo. TWRP doesn't open only thing i can do is go into android recovery mode then I get some errors.

    #fail to open recovery_cause
    #:fail to mount /efs (invalid argument)
    #dm-verity verification failed...

    -- I tried to flash twrp latest file but my odin error is "only official released binaries are allowed"
    -- I re flashed the phone to 3 different stock roms and still the same issue.

    Please assist.

    Flash the stock ROM that was in the phone when you started all this (the same version number and the same update date). Samsung frequently sets the latest version number when the phone updates, and you can't flash an earlier ROM any longer.

    If that still doesn't work, either find a JTAG service on eBay that handles the G955F, or contact Samsung.

    HI, Thanks for the reply, I did flash stock rom but then I still get the android recovery errors. I flashed a combination firmware and know my phone is stuck at the Factory Binary logo. unfortunately I got now jTag Service close to me. Samsung wants to send my phone away for repairs after I paid but then cant confirm if it will be fixed or not.
