The Ultimate Guide: How to Downgrade PS4 Firmware 9.60 to 9.00

Method 1: The Teensy NAND Reflash (For CUH-10xx, CUH-11xx, CUH-20xx)

This is the most documented method for fat and slim models.

Equipment Needed:

  • Teensy 4.0 or 4.1 board
  • Soldering iron & flux (fine tip)
  • MicroSD card (for Teensy)
  • PS4 NOR/NAND Clip (optional but recommended) or direct wires.
  • A backup of your 9.00 NAND (critical).

Step-by-Step Process:

  1. Disassemble your PS4 completely to access the motherboard. Locate the NAND chips (usually near the HDMI port).
  2. Solder wires from the Teensy to the test points on the PS4 motherboard (SCK, CS, MISO, MOSI, VCC, GND).
  3. Flash the Teensy with the "PS4 NOR Validator" or "recovery firmware" (available on developer forums like PSX-Place).
  4. Connect your PC to the Teensy via USB. Use a tool like NandPloader to dump your current 9.60 firmware to a file (backup in case of failure).
  5. Erase the target sectors on the PS4 NAND.
  6. Write your old 9.00 dump back to the NAND via the Teensy.
  7. Reboot. The console will likely show error CE-34788-0 because the fuses are mismatched. You then need a modified 9.00 recovery PUP that disables the fuse check.

Success Rate: 60% (Most failures happen due to bad soldering or corrupted dumps). how to downgrade ps4 9.60 to 9.00
