Because hardware downgrading is too risky and difficult for the average user, the community relies on alternative paths to access homebrew.

There are currently only two proven, hardware-based methods to revert a PS4 to a lower firmware version. Both require technical skill and hardware tools. 1. The Revert Method (The "Syscon Patch" Method) Used as a hardware flasher to read and
