Help Fairphone 4

I’d suggest a clean install of A13 so you get your get_unlock_ability back to 1, in case something goes wrong:

  • Download the latest factory images
  • Open (don’t run) the file flash_fp4_factory.command and set AUTO_REBOOT="true" in line 18 to "false"
  • Run the installation as usual and don’t boot into Android userland afterwards
  • (Optional) Check that fastboot flashing get_unlock_ability returns 1
  • (Optional) Lock the critical partitions with fastboot flashing lock_critical
  • Check that fastboot flashing get_unlock_ability returns 1
  • Without rebooting lock the bootloader with fastboot flashing lock
