The PlayStation 4 (PS4) remains one of the most popular gaming consoles in history, celebrated for its robust library of exclusive titles and stable online ecosystem. Central to its operation is the firmware—system software that controls everything from security to feature updates. As of mid-2024, the latest firmware versions, such as 13.02, are designed to patch vulnerabilities, improve system stability, and block exploits used for homebrew or piracy. In contrast, firmware version 9.00, released in late 2021, is widely known in the modding community for containing a critical USB-based exploit. Consequently, a recurring question emerges: Can a PS4 on firmware 13.02 be downgraded to 9.00? The short answer is no, but understanding why requires a deep dive into the hardware and cryptographic architecture of the PS4.

You must disassemble the PS4, solder wires to the NOR chip, use a flash programmer (like a Teensy++ or Raspberry Pi) to rewrite the chip with the older dump, and then reinstall the 9.00 firmware via Safe Mode.

However, a highly technical exists for specific consoles. The Reality of PS4 Downgrading

You must completely disassemble your PS4 to gain access to the motherboard. Locate the NOR flash memory chip and the specialized Syscon chip. Solder your hardware programmer directly to the designated trace points on the board. Use your flashing tool to pull exact, identical digital copies of both chips.
