As of early 2026, there is no public software-based jailbreak for version 13.02. Some exploits, such as those utilizing the VUE app, have been theorized to work up to 13.02, but these are typically for limited functions rather than a full system jailbreak.
If you updated from a version like 12.52 to 13.02, you can only revert back to 12.52.
Furthermore, the update process itself is cryptographically sealed. Sony signs every official firmware update file (PUP) with a private key. The PS4’s boot ROM contains the corresponding public key and will only install a firmware that is cryptographically verified and, crucially, in version number than the current one. This is known as an anti-rollback mechanism. Even if a user managed to bypass the efuse check, the bootloader would reject the older, 9.00 update because its security version counter is lower. Any third-party tool claiming to “factory reset” or “force flash” an older firmware is simply lying; the signature check is baked into the read-only memory of the console. ps4 downgrade 13.02 to 9.00

If you still wish to attempt a revert to your previous firmware version, you will need: This is known as an anti-rollback mechanism
There are currently only two primary ways to "revert" firmware, both of which are technically demanding:
