Even if you possess advanced micro-soldering skills, If your console was running 13.00 before updating to 13.02, hardware reversion will only take you back to 13.00. It cannot bridge the multi-year gap back down to 9.00. Debunking "PS4 13.02 to 9.00" Download Scams

If you bought a PS4 that was already on 13.02, or if you updated past 9.00 a long time ago, the 9.00 data is permanently overwritten. For 99% of users, this method is unavailable. Why People Want Firmware 9.00

As of early 2026, firmware 13.02 is considered a "security patch" version.

To move from a high firmware (13.02) to a lower one (9.00), you must technically overwrite the flash memory (NOR chip) on the motherboard.

However, a highly technical exists for specific consoles. The Reality of PS4 Downgrading

Every time you install a major system update (from 9.00 to 10.00, 10.00 to 11.00, etc.), a tiny electronic fuse (eFuse) inside the Syscon chip (System Control microcontroller) is physically "blown." You cannot un-blow an eFuse. It is a one-way street.

This process is incredibly complex and dangerous, requiring advanced electronics skills. It is not a software solution.

The XMB menu loaded. The icons were crisp. The time displayed in the corner.

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.

: Attaching a specialized tool, such as a Raspberry Pi Pico , directly to the Syscon chip pins.

The chips are wired into a hardware flasher (like a Raspberry Pi Pico or Teensy board) to dump the raw binary data onto a PC.

Given the difficulty of downgrading, here are your most practical options:
