The extractTarFork() process ended with ERROR: 255 is one error you might bump into in TWRP custom recovery, especially when you're trying to restore a backup. This is usually as a result of a mount problem with the userdata partition.

  3. Go back and try restoring the TWRP backup again

Important Notice
  • Try doing a fresh backup and restoring to be certain that the error is from the previous backup (which you need to restore) and not from a mount point error
  • There's a good chance that the userdata fix doesn't work for you so try the same fix on other partitions
  • If the error persists then consider creating a flashable zip from your TWRP backup. Getting the mount points right (in updater-script) is crucial

The problem is likely with data in the TWRP backup. Try restoring the backup without data and see if the error persists first
