While downgrading a PS4 from 13.02 to 9.00 is technically possible in 2026, it is a highly technical, hardware-intensive, and dangerous procedure. It requires soldering skills, special tools (like a Syscon programmer), and significant patience.
To perform a 1302 to 900 conversion, you absolutely require:
You need a previous backup of your Syscon and NOR dumps that were taken while the console was on 9.00, or a method to patch the current dumps to represent 9.00. The Downgrade Method (Reversion Procedure)
However, moving from a significantly newer firmware like 13.02 back to 9.00 is not a straightforward software update. It requires advanced hardware techniques. This article explores the realities, risks, and methods involved in attempting a PS4 firmware downgrade in 2026. Why Downgrade from 13.02 to 9.00? ps4 downgrade 1302 to 900
If you are uncomfortable with soldering, there are currently no reliable "software-only" methods to downgrade from 13.02. The community is focused on developing newer hacks, but as of May 2026, a hardware flash is the only path.
What tools (like Raspberry Pi or Teensy) you already own
You pass these file dumps through validation software on your PC. This step is critical because a single corrupted byte can permanently brick your console. The software analyzes the files to check if the previous firmware version (e.g., 9.00) is still intact in the backup slot. 3. Patching the Syscon While downgrading a PS4 from 13
This system control chip tracks and validates the console's active and backup firmware versions.
There is a legitimate technique called Firmware Revert , but it requires advanced micro-soldering skills and specific hardware.
Sony's official policy is that . Their system software is designed to be a one-way street, with each update introducing security patches and new features. Why Downgrade from 13
If you decide to proceed with a hardware revert, the process typically involves the following technical steps as discussed in modding communities like Reddit YouTube guides Hardware Tools : You need specialized equipment such as a Teensy 2.0++ Raspberry Pi CH341A programmer to read and write to the console's chips. Dumping the Flash : You must solder wires to the
The console will request a system reinstall file. Plug in a USB drive formatted to FAT32 containing the official (not the standard update file) placed in the PS4/UPDATE/PS4UPDATE.PUP folder structure. Follow the on-screen prompts to initialize the system. Alternative Path: Exploiting Intermediate Firmware
If the error persists, this is the most reliable method. You will need a USB drive and access to a computer.
