We demonstrate the exploitation of this vulnerability by creating a custom firmware image that downgrades the PS4's firmware to a vulnerable version. We then use this image to exploit the PS4, demonstrating the potential for arbitrary code execution. ps4 downgrade 1302 upd
You can only revert to 13.00.

PS4 jailbreaks are released for specific firmwares. As of early 2026, the last public jailbreak works on . If you are on 11.00 or lower, you can still use the PPPwn exploit. If you are on 12.00+, no public jailbreak exists. Downgrading is impossible, so your only choice is to wait—or sell the console and buy one on 11.00 or lower.
No. Restoring a system backup from a lower firmware onto a higher-firmware console will trigger the 1302 error immediately.
