Instead of breaking your 13.02 console, try to purchase a used PS4 already on firmware 9.00 or lower.

The PS4 architecture maintains (Slot 0 and Slot 1) for its core operating system files.

Downgrading your PS4's firmware may void your warranty and potentially brick your console. Proceed with caution and at your own risk.

Is it possible to jailbreak or downgrade a PS4 running firmware 13.02?

Some online sellers claim to “downgrade from 13.02 (or 10.02) to 9.00” using a “1302 to 900” method. This is or refers to:

If you see “1302” or “900” errors without wanting risky hardware mods:

“Cannot start the PS4. Connect the DualShock 4 via USB cable, then press the PS button.” (Error SU-41350-3)

Therefore, you can only revert from 13.02 to 9.00 if you updated your system without installing any versions in between.
