Downgrading a PS4 from firmware 13.02 to 9.00 is a technical impossibility for the overwhelming majority of users due to Sony’s fuse-based anti-rollback mechanism, cryptographic signatures, and the lack of any kernel exploit on 13.02. While hardware-level downgrades exist in theory, they require advanced soldering skills, expensive equipment, and carry a high risk of permanent bricking. The most practical advice for users interested in PS4 modding is to maintain a console on firmware 9.00 or lower if they already own one, and never update beyond a vulnerable firmware. For those already on 13.02, the only realistic options are to enjoy the console as intended by Sony or purchase a second-hand PS4 confirmed to be on a lower firmware. As the PS4 generation winds down, the window for easy exploitation has closed, and no legitimate software downgrade path from 13.02 to 9.00 exists or is likely to appear in the future.
Downgrading requires physical manipulation of the console's motherboard. The Reality of "Downgrading" a PS4
: The exact system version you used immediately before your last system update.
The chips are soldered back onto the motherboard. ps4 downgrade 13.02 to 9.00
To move from a high firmware (13.02) to a lower one (9.00), you must technically overwrite the flash memory (NOR chip) on the motherboard.
: The system version you are currently running (e.g., Firmware 13.02).
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. Step 2: Patching the Syscon Registers Downgrading a PS4 from firmware 13
: If your previous version was 9.00, some specialized repair shops may offer a hardware downgrade (Revert) service, though it is often more expensive than just buying a different console. Downgrade ps4 13.02 to 13.00? - Facebook
The PS4 homebrew scene has made remarkable progress. Firmware versions up to 13.00 have been fully exploited and implemented, though public exploits are not available for all versions. The exploit known as "Poops" (GoldHEN) currently supports firmware versions from 9.00 up to 13.00, but 13.02 is not yet supported. With continued development, it is possible that a jailbreak for 13.02 may eventually emerge.
Downgrading a Go to product viewer dialog for this item. from firmware to 9.00 is not possible through software alone and is extremely difficult even with hardware modifications . PS4 security is designed to prevent software-based "reverting" to ensure users remain on the latest version for security and network features. The Quest for 9.00: The "Golden" Firmware For those already on 13

If you search for "PS4 downgrade 13.02 to 9.00" on platforms like YouTube, TikTok, or shady forum boards, you will encounter dozens of tutorials claiming to offer "Downgrader Homebrew PKG files," "jailbreak recovery discs," or custom firmware USB installers.
: Reverting even to the previous version requires advanced "Syscon" and "NOR" flashing. This involves soldering components like a Teensy or Raspberry Pi (Pico) to the motherboard and using complex software tools to rewrite the console's internal memory. Common Misconceptions
