Keep your PS4 on firmware 9.60. The PlayStation homebrew scene continuously develops new WebKit entry points and kernel exploits. A software-based jailbreak for 9.60 or higher may be released in the future.
If your console's previous slot does not contain version 9.00, or if you do not have the micro-soldering experience required for this procedure, consider these alternative paths:
Reassemble the console with fresh thermal paste and thermal pads. Boot the PS4 directly into .
For interacting with the programmer and handling the firmware images. The Process: Step-by-Step Overview how to downgrade ps4 9.60 to 9.00
: The PS4 has two firmware "slots" (active and inactive). When you update, the old firmware stays in the inactive slot. You can only revert if your previous version was 9.00. If you updated from 9.03 to 9.60, you can only revert to 9.03.
Go to Settings > System > System Information on your PS4 to confirm you are on version 9.60 . Jailbreaking only works on specific, supported firmware versions.
This is so expensive (often $150–$300) that you are better off selling your 9.60 console and buying a used console on 9.00 or lower. Keep your PS4 on firmware 9
However, some developers (e.g., TheFlow, SpecterDev) have hinted at exploits beyond 9.00. Stay on 9.60 and monitor sites like Wololo.net or /r/PS4Homebrew for news.
When the PS4 updates, it overwrites one of its two boot slots (Slot A and Slot B) with the new firmware, leaving the previous firmware data in the inactive slot. If your console was directly on firmware 9.00 right before it updated to 9.60, the 9.00 data still exists inside the inactive slot of your NOR chip.
This is an advanced hardware modification. It is not recommended for beginners. Required Tools A high-quality soldering iron and hot air rework station. Fine copper enamel wire (30 AWG). If your console's previous slot does not contain version 9
Look for used PlayStation 4 consoles on marketplaces. Ask sellers to confirm the system firmware version in the system settings before purchasing.
(the version you were on immediately before the last update). The Constraint:
Solder your Teensy microcontroller to the specific debug points corresponding to your PS4 motherboard revision (e.g., SAA-001, SAB-001, CUH-1200 series). Use Syscon reading scripts to extract the firmware payload from the chip. Ensure you make multiple copies of this dump as well. Step 5: Patch the Syscon and NOR Data
