The PS4 motherboards feature (Slot A and Slot B). When you update your console from 9.00 to 13.02, the console keeps 9.00 in the inactive slot and writes 13.02 to the active slot. It then updates the Syscon chip to mark 13.02 as the only allowed runnable version.
The short, direct answer is: Sony has designed the PS4's security architecture to make a true, arbitrary downgrade from a higher firmware to a lower one impossible using conventional means. However, there is a hardware-intensive procedure known as a "Firmware Revert" that allows a console to switch back to a previously installed firmware, but this process requires significant skill, specialized equipment, and was possible only if a backup was made before updating.
If you have verified that your console satisfies the necessary conditions and you possess the required technical skills, the core reversion procedure unfolds across the following phases: Step 1: Extracting the NOR Flash ps4 downgrade 1302 to 900 top
This is the most important takeaway:
You can only revert the console back to the version stored in the secondary slot. If your console went from 9.00 straight to a later firmware without intermediate updates, 9.00 may still be present. If you updated progressively through multiple versions, your inactive slot will only contain the version installed immediately before your current one.

By understanding the motivations, technical aspects, and risks involved, users can make informed decisions about downgrading their PS4's firmware. However, it is essential to emphasize that downgrading should only be attempted by experienced users who fully comprehend the process and potential consequences.
The PS4 firmware version 9.00 is widely considered one of the most desirable "golden firmwares" in the modding community. It sits in a sweet spot where the system is stable, but specific security vulnerabilities allow for homebrew and backup loading. The short, direct answer is: Sony has designed
The only legitimate way to lower a PS4’s firmware is through a complex hardware modification process known as a . Even then, a hardware revert only lets you go back to the single firmware version that was installed on your console immediately before your last update .
