How to Revert the PS4 to a Previous Firmware (Full Tutorial)
As of 2026, new solutions have emerged to simplify this process, including PCB modules that can be installed to allow switching between firmware versions via a smartphone app. These still require initial soldering but automate the "swapping" process. 4. Post-Downgrade: Jailbreaking to 9.00
In the world of console modding, few phrases generate as much hope and confusion as "PS4 downgrade." With Sony continuously pushing firmware updates—the latest stable being 10.50 as of mid-2024—many users who stayed on the coveted jailbreak-friendly firmware 9.00 are now asking the million-dollar question:
Downgrading a from firmware 10.50 to 9.00 is not possible through simple software menus or factory resets . The only functional method, often called "Reverting,"
This method allows reverting from a current firmware to the previous firmware version - for instance, from 11.02 to 10.50 - but does typically allow skipping multiple versions. ps4 downgrade 10.50 to 9.00
Reassemble the console and boot into Safe Mode to install the official 9.00 recovery firmware.
This article is for educational purposes only. Downgrading your PlayStation 4 firmware violates Sony’s Terms of Service. It can result in a permanent console ban from PSN (PlayStation Network), loss of warranty, and complete system bricking. Proceed at your own risk.
The PlayStation 4 firmware version 9.00 is highly sought after by enthusiasts. This specific version allows for the execution of the popular "p00bs4" jailbreak, opening up the console to homebrew apps, backups, and custom themes. If your console updated to firmware 10.50, you might want to return to 9.00.

Reverting a PlayStation 4 from firmware to 9.00 is not possible through standard software menus or USB updates alone. However, it can be achieved through a highly technical hardware process known as firmware reverting . The Core Concept: Slot Switching
: If you're on 10.50, the PPPwn exploit works on this firmware version. While the homebrew ecosystem isn't as mature as on 9.00, some functionality is available, including limited payloads.
Many users sell their high-firmware consoles on marketplaces and buy a used PS4 specifically listed as "Firmware 9.00 or lower." 🚀 Next Steps If you want to try the hardware route, I can help you find:
This method is considered experimental and often fails, as many Syscon chips aren't compatible. Given the high cost of equipment and the extreme risk of bricking, buying a console on 9.00 is often cheaper, safer, and more practical than attempting a downgrade. Post-Downgrade: Jailbreaking to 9
Use the Raspberry Pi to write the patched dump back to the NOR chip.
| Component | Function | Downgrade Barrier | | :--- | :--- | :--- | | | One-time programmable memory inside the APU | Each update burns a specific fuse. 10.50 burns fuses that 9.00 does not expect. 9.00 checks for intact fuses; finding burnt ones causes a hard brick. | | Syscon (System Controller) | Secondary microcontroller managing power and security | Stores the "Lowest Usable Version" (LUV). Once updated to 10.50, Syscon rejects any request to boot 9.00. | | SAMU (Security Asset Management Unit) | Handles encryption keys | Each firmware version has unique keys. 9.00 cannot decrypt 10.50’s secure data, nor can it boot without certain 10.50-specific patches. |
You will need tools like a Raspberry Pi, jumper wires, and soldering equipment. How to Downgrade: The General Process (Hard Downgrade)
Using the application, you will modify your dumps to swap the active slots. You will create a "Patch" that tricks the Syscon into thinking the inactive slot (9.00) is the correct, official version. Step 4: Reverting/Flashing
: This is a dedicated security microchip that acts as the gatekeeper. It keeps a permanent physical record of the current firmware version and prevents older software from executing.
