Hello.

You can try to remove Samsung Account via "Reset FRP/Reactivation/EE" operation.

i try it say operation failed tried it a few tyms always the same

Problem with reset of FRP lock can occur if phone has latest firmware. Samsung disabled ability to remove FRP lock in latest firmwares.

Try to write "SBOOT_G920F_OJ1" Sboot file from the Support Area as a firmware, then repeat "Reset FRP/Reactivation/EE" operation. Post here result and full Software log of performed operations.

[Octopus box]

You should write any firmware with the same Android version, as has the phone. If You are not sure about Android version - use Android 6.0.1 firmware.
