: This method requires a Renaissance Syscon chip (identifiable by "A0" marked on the chip). It also requires advanced micro-soldering skills to connect to the Syscon and NOR chips. Hardware Reversion Process (Overview)
The short answer is The longer answer involves understanding why it’s nearly impossible, and what extreme (expensive) hardware alternatives exist.
Before attempting any hardware modification, you must verify two things:
You cannot simply "install" an older firmware version from a USB drive on a PS4. Sony's security prevents any software-only downgrade to protect against jailbreaking.
