Sony embeds encryption keys into each update. Higher firmware versions revoke the digital signatures of older firmware versions.
To change the active firmware slot, you must force the system controller chip to re-evaluate its validation sequence. The standard workflow follows these precise technical steps:
If your console went from 9.00 to 10.00, then to 11.00, and eventually to 13.02, a hardware revert will only take you back to the firmware right before 13.02. It cannot skip backward across multiple major updates. ps4 downgrade 13.02 to 9.00
The obsession with firmware 9.00 comes down to the homebrew community.

Firmware 13.02 burns a specific set of fuses that are not present or are less advanced in version 9.00. Downgrading would require resetting these fuses, which is physically impossible without specialized equipment and direct hardware modification (e.g., replacing the Southbridge chip entirely). For the average user, there is no software method to circumvent this. Thus, any claim of a “downgrade” from 13.02 to 9.00 via a simple USB drive or software tool is fraudulent.
A software-based, one-click downgrade from PS4 firmware 13.02 to 9.00 is completely impossible. Sony designed the PS4 security architecture specifically to prevent users from installing older software versions. However, a highly complex, hardware-based method exists that allows certain consoles to revert to a previous firmware version under very specific conditions. Why Software Downgrading is Blocked
