: The PS4 motherboard stores the current firmware in "Slot A" and the immediate previous version in "Slot B". Requirements : You can only revert to the exact previous version
: You must be comfortable with fine-point soldering on the motherboard to "glitch" the Syscon (system controller) and read/write to the NOR flash. General Downgrade Process (Hardware Revert)

The PS4 stores system data in two alternating "slots" on its motherboard—Slot A (active) and Slot B (inactive/previous). When you update to 13.02, your previous firmware (e.g., 12.50 or 12.00) remains in the inactive slot as a failsafe. "Downgrading" is essentially the process of forcing the console to boot from that previous slot. Requirements and Hardware
Firmware 13.02 is a recent security-focused update from Sony. Typically, these updates don’t add many user-facing features but focus on patching vulnerabilities discovered in earlier 13.xx or 12.xx iterations. If your PS4 is on 13.02, it is considered a "patched" console, meaning it cannot currently take advantage of older jailbreaks (like the popular 9.00 or 11.00 exploits).

: You can "switch" back to the previous firmware by physically accessing the console's Syscon and NOR flash chips. When you update to 13
You bought a used PS4 from a seller who claimed it was on “low firmware” (e.g., 6.72 for jailbreaking). You boot it up, but it keeps asking for an update. When you try to install the low firmware via USB, you get the 1302 error. This happens because the previous owner updated the console but then sold it after a hard drive wipe. The Syscon chip remembers the higher firmware.
You're looking for a comprehensive guide on downgrading your PS4 from firmware version 13.02. I must emphasize that downgrading your console's firmware can potentially brick it, making it unusable. Proceed with caution and at your own risk.
