Any file claiming to perform this downgrade completely via software or a standard USB flash drive is fake. These files often contain malware designed to infect your computer or survey scams designed to generate advertising revenue. Always cross-reference downgrade claims with trusted, established console modification forums.
If your console is running version 13.02, performing a hardware downgrade is often impractical due to cost, risk, and tool availability. Consider these alternative paths forward:
Even professional downgrade services cannot bypass the fundamental limitation that you can only revert to the immediate previous firmware. If 9.00 is not the version directly before 13.02 in your update history, no amount of soldering will get you there. ps4 downgrade 13.02 to 9.00
: Use computer software to extract the current 13.02 system image files from the chips.
The core conflict regarding the downgrade from 13.02 to 9.00 lies in the reality of hardware security. Unlike early gaming consoles where software versions could be swapped with relative ease, the PS4 employs a sophisticated security architecture involving "fuses" on the motherboard. These are not physical glass fuses, but electronic "efuses" that are blown by the system software during the update process. When a PS4 updates its firmware, it burns specific fuses to prevent the system from ever booting an older version of the software. This creates a one-way street; once a console has passed a certain firmware threshold, the hardware itself recognizes the older software as unauthorized.

Is it possible to downgrade a PS4 from firmware 13.02 to 9.00? The short, definitive answer is
When you update to 13.02, your previous firmware (e.g., 12.52) is moved to the inactive slot. The Limitation: If your console is running version 13
Even if you have the hardware skills, this revert is only possible if the previous firmware slot still contains the lower version you want. As noted, certain actions will overwrite this slot.
As of early 2026, the PS4 scene has advanced beyond the need to downgrade to 9.00 for many users: How to Jailbreak the PS4 on 9.00
There is only one legitimate, highly complex hardware method capable of rolling back a PS4's firmware. This is known in the modding community as the . The Catch: You Must Have a Backup
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.
