Downgrading a PlayStation 4 from a high firmware version like
is not possible through standard software or system settings. Sony uses security measures and a "syscon" chip to prevent users from reverting to older firmware versions, primarily to prevent piracy and maintain system integrity. ftp.bills.com.au Why Downgrading is Restricted Anti-Rollback Protection
: The PS4's hardware and software are designed to only accept firmware updates that are equal to or newer than the currently installed version. Hardware Reversion
: A "revert" is theoretically possible only by using advanced hardware modification techniques, such as soldering and using an external programmer to flash a backup of the system's previous state. This requires that you already made a hardware backup of your console's unique files while it was still on version 9.00. Current Limitations Software Methods
: There is no official or legal software that allows you to click a button and downgrade. Security Risks
: Be cautious of websites or videos claiming to have a "downgrade tool" for version 13.02. These are frequently scams or malware, as no such public software utility exists for these versions. Future Support
: Sony has indicated that support for the PS4 will gradually fade starting in April 2026 , which includes a reduction in patches and server updates. ftp.bills.com.au
If your goal for downgrading is to use homebrew or specific exploits available on version 9.00, your only reliable option is to find and purchase a used PS4 console that is already running firmware version 9.00 or lower. specific exploits
available on version 9.00 or how to check the firmware on a used console? Downgrade PS4 To 9.00: Is It Possible? - Ftp
Verdict: As of the current system software version 13.02 (released March 2025), a direct software-based downgrade from 13.02 to 9.00 is impossible on any standard retail PlayStation 4 console (all models: CUH-10xx, 11xx, 12xx, 20xx, 21xx, 22xx, Pro CUH-70xx, 71xx).
The PS4’s security architecture uses irreversible one-time programmable (eFPROM) fuses that blow with each firmware update. Once updated past a certain version, the console permanently stores the minimum allowable firmware version in hardware. No public tool, hack, or modification can revert this on a retail unit without hardware-level replacement of the motherboard’s Syscon/南桥 chip.
However, this request highlights a common misunderstanding about jailbreaking, downgrading, and the exploit landscape. This write-up explains why it is impossible, what the real options are for low-firmware PS4s, and the risks of scams promising downgrades.
Scour YouTube or shady forums, and you will find videos titled "PS4 Downgrade 13.02 to 9.00 100% Working." These are scams. They usually involve:
PS4UPDATE.PUP file that is actually malware.The Truth: You cannot downgrade firmware 13.02 via USB. Even recovery mode (Safe Mode #7 - Initialize PS4 (Reinstall System Software)) requires a firmware version equal to or higher than your current installed version. Since version 9.00 is lower than 13.02, it will never work.
Let us state this clearly: There is no software tool, no USB file, and no "reset" that will downgrade a standard retail PS4 from 13.02 to 9.00.
Sony uses "efuses" (one-time programmable electronic fuses) inside the Syscon chip on the motherboard. When you update your firmware, these efuses are physically blown. The bootloader checks these fuses every time you turn on the console. If the firmware version on your hard drive is lower than what the efuses expect, the PS4 will refuse to boot.
You cannot simply insert a USB drive with firmware 9.00 and run an update. The console will recognize the version as old and throw an error message (usually "The update file is corrupted" or "SU-42134-2").
Many online tutorials and YouTube videos claim to offer “easy downgrade tools” for the PS4. These are invariably scams or malware. Running unverified executables on a PC or installing “update” files from untrusted sources can lead to data theft, ransomware, or permanent system corruption. Even legitimate attempts using recovery firmware (PS4UPDATE.PUP) from version 9.00 will be rejected by a console on 13.02 with error codes such as “CE-34788-0” (incorrect system software version). Repeated failed attempts do not degrade the hardware, but they waste time and create false hope.
Even this advanced method has massive hurdles when dealing with version 13.02:
If you are currently on Firmware 13.02:
The cost of buying a used PS4 on 9.00 ($150–$200) is significantly cheaper than the equipment and risk required to downgrade your 13.02 unit ($300+ in tools + risk of total loss).
