The Process: By manipulating the Syscon (System Controller) and the Flash memory, a technician can sometimes force the console to boot into the previous firmware slot.
If you did not back up your console's unique flash files while you were on a lower firmware, a hardware revert to that specific version is generally impossible. Why Users Want to Downgrade

Requirements: This requires advanced soldering skills, a Teensy or Raspberry Pi, and a backup of your console’s specific NOR/Flash files taken before the update.
