PS4 Firmware Revert Guide by @MaxLab81


Recommended Posts

Back in early July of this year, I created this thread, which discusses the possibility of downgrading your PS4, @wildcard's method has been made a reality and you can  now downgrade or revert to a lower firmware following a tutorial by MaxLab81.

Firstly I would like to note that this method is being referred to as a revert and not a downgrade, this is because you are not actually downgrading from a higher firmware to a lower one, instead you are returning to a lower that you have already backed up, you are reverting your system to that lower firmware, 6.72 as an example.

 

I would also like to note that this method will not let you play 7.55 games on 6.72 or lower.

 

To use this revert guide you will need the following (Taken from the actual guide)

  • R5F100PLA (for SAA and SAB) or R5F100LLA (for SAC, SAD ecc ecc) RL78 family stock.
  • E2 Lite Renesas.
  • Teensy 4.0 (sysglitch).
  • Teensy 2.0++ (dump nor).
  • Serial UART to USB.
  • TQFP 100pin 0.5mm.
  • Soldering Station.
  • Patience.
