The only way to downgrade a PS4 is through a "Firmware Revert," a hardware-based modification that works by manipulating these chips directly.
The search term "PS4 downgrade 13.02 to 9.00" leads thousands of gamers to broken dreams each month. It is not a simple software download. It is an advanced hardware modification requiring surgical soldering and reverse engineering knowledge.
Firmware 13.02 burns a specific set of fuses that are not present or are less advanced in version 9.00. Downgrading would require resetting these fuses, which is physically impossible without specialized equipment and direct hardware modification (e.g., replacing the Southbridge chip entirely). For the average user, there is no software method to circumvent this. Thus, any claim of a “downgrade” from 13.02 to 9.00 via a simple USB drive or software tool is fraudulent.
Some users ask about installing a modchip to enable downgrading. While hardware modifications exist for the PS4—such as installing modchips or modifying the motherboard—these are typically focused on enabling specific features like playing backups rather than facilitating firmware downgrades. Even with hardware modifications, reverting firmware version remains a complex process that requires specific Syscon and NOR programming. ps4 downgrade 13.02 to 9.00
Potentially high
A: The firmware kernel is stored partially in the Syscon chip and partially on the NOR flash of the motherboard. Replacing the HDD will not downgrade your firmware.
Firmware 9.00 represents a golden era for PS4 homebrew development. The only way to downgrade a PS4 is
Write-up date: April 2026. Based on public PS4 hardware/software research by the Scene (CTurt, fail0verflow, FlatZ, SpecterDev, TheFlow, etc.)
Given the extreme difficulty of the hardware method, the most practical advice for the overwhelming majority of users is to and use the money to buy a console that is already on firmware 9.00 or lower . Many online marketplaces and local retro game stores will list a console's firmware version, allowing you to find one ready for homebrew.
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: It is an advanced hardware modification requiring surgical
The PS4 keeping system files in two distinct slots on its internal storage flash memory (the NOR/NAND chip). When you update from firmware A to firmware B, firmware A remains briefly in the secondary slot as a backup until another update occurs. Requirements for a Successful Revert
: There is no way to downgrade via USB or DNS . Reverting requires complex hardware modification, including soldering to the Syscon and NOR chips.
Many downgrade guides online refer to "13.02 to 9.00" but often confuse users. Here is the specific problem with 13.02:
