Ps4 Downgrade 13.02 To 9.00 -
From a software perspective, the downgrade is blocked by a hardware mechanism on the motherboard. The console’s firmware data is not stored solely on its hard drive. It is also written to a few small, read-only, and encrypted chips permanently soldered onto the motherboard. These chips, particularly a key component called the , act like a secure vault. They keep a log of your console's update history and are designed to block the installation of any system software that is older than the one currently installed. This is a security measure implemented by Sony to prevent just this sort of rollback.
If you are still on firmware 9.00 or lower, you can prepare for the future by backing up your "EAP Key" (Encryptions Key) using a jailbreak tool. However, if you are already on 13.02, it is too late to do this without a hardware flasher.
This hardware exploit only allows you to step back to the that was installed on that specific console. ps4 downgrade 13.02 to 9.00
This article is for educational and informational purposes only. Downgrading your PS4 firmware requires advanced hardware manipulation, voids your warranty, violates Sony’s Terms of Service, and carries a high risk of permanently bricking your console. Proceed at your own risk. This content is not endorsed by Sony Interactive Entertainment.
Do not attempt a downgrade unless you fully accept the high technical, legal, and bricking risks, have specialized tools/experience, and are prepared to lose the console or online access. For backwards compatibility or running legacy software, consider safer alternatives (buying a compatible older console or using emulation on a PC).

While the main CPU (APU) enforces the rule, the Syscon chip (a smaller microcontroller) holds the truth about your firmware version. Advanced modders have learned to:
If you're reading this because you've accidentally updated to 13.02, there is a small chance you may still have a path back to a lower firmware. The PS4 maintains an "emergency backup" of the immediate previous firmware version, stored in a separate location on the motherboard. This is part of a mechanism designed to allow the console to revert if something goes wrong during an update installation.
