The only reliable method for a firmware downgrade involves a hardware procedure called a "firmware revert". This process leverages the fact that the PS4 stores data from your current and previous firmware versions on the motherboard. By carefully manipulating this data, you can revert to the older version.
Downgrading a PlayStation 4 firmware , but it is highly complex and cannot be achieved by simply running a software program on a Windows PC. Sony designed the PS4 with strict hardware-level security to prevent rollback attacks (downgrading). Here is how authentic PS4 downgrading actually works: 1. The Syscon and Nor Chips

The PlayStation 4 console has a massive library of games, but its strict firmware updates often restrict users from enjoying homebrew, mods, or Linux emulation. Because jailbreaks are usually limited to specific, older firmware versions (like 9.00 or 11.00), many players look for a quick way to roll back their console's software.
The PlayStation 4 remains one of the most successful gaming consoles of all time, boasting a library of thousands of titles.
