If the above steps don't work, you may need to use a PS4 exploit tool to gain access to the system. This step is optional and requires technical knowledge. Note: This is a high-level overview
| Myth | Truth | |------|-------| | “A USB drive with 9.00 recovery will work” | No. The PS4 checks that the installed firmware is higher than the current one. | | “Initialize or factory reset will restore 9.00” | No. Initialization only erases user data; firmware stays on 9.60. | | “Downgrader tools from mod shops work” | 99% are fake. The real ones require hardware mods and cost hundreds. |
There is only one known method to downgrade a PS4 from a higher firmware to a lower one, including from 9.60 to 9.00. It's a complex hardware-based procedure known as a "Syscon revert". This method doesn't install a new, old firmware; instead, it tricks the PS4 into booting from its backup firmware slot.
