Ps4 Downgrade 1302 To 900 Today

This review analyzes the feasibility, technical requirements, and risks of downgrading a Go to product viewer dialog for this item. from firmware 13.02 to 9.00, as of early 2026. 📝 Executive Summary: PS4 13.02 to 9.00 Revert

Feasibility: Technically possible, but highly difficult and not a standard software downgrade.

Method: Requires physical hardware modification (micro-soldering) to the SYSCON chip and a NOR programmer.

Verdict: Not recommended for beginners. Only suitable for experienced electronics modders with proper equipment. 🔧 What is the 13.02 to 9.00 Downgrade?

The method involves utilizing a "Firmware Revert" technique. The PS4 keeps the current and previous firmware information saved on the motherboard (in the Syscon chip).

If you updated to 13.02, this method allows you to swap the current active slot with the previous one. However, you can generally only revert to the version immediately preceding your current update (e.g., from 13.02 to 12.52 or 13.00), not straight back to 9.00 unless the console was already modified or kept in a "paired" state. ⚠️ Pros and Cons Pros Cons Potential to jailbreak if the previous firmware is ≤11.00is less than or equal to 11.00 Requires severe soldering skills (lifting pins) Bypasses accidental updates Risk of bricking the console permanently Allows use of custom firmwares/Linux Requires hardware tools (e.g., Pinecil, magnifiers) 🛠️ The Process (High-Level) Firmware Revert - ConsoleMods Wiki ps4 downgrade 1302 to 900

Disclaimer: This guide is for educational and research purposes only. Modifying your console’s firmware carries significant risks, including the potential for permanent hardware damage (bricking), voiding your warranty, and the risk of console bans from PlayStation Network. Proceed at your own risk.

Why Would Anyone Perform This Downgrade?

There are two primary camps of users searching for "PS4 downgrade 1302 to 900":

  1. The Repair Technician: You have a console with a broken Blu-ray drive. After replacing the drive, you get error 1302. You want to bypass the BD check entirely or remarry the drive using a lower firmware threshold (9.00) where the security checks are weaker.

  2. The Jailbreaker: You accidentally updated your PS4 from a jailbreakable firmware (9.00 or lower) to 10.00 or higher. Sony’s update rewrote the BD controller. Now you cannot go back because the BD firmware (now 10.x) is higher than the target 9.00. You need to downgrade the drive’s firmware before you can downgrade the system’s firmware.

What Do "1302" and "900" Actually Mean?

Before attempting any downgrade, you must understand the language of your PS4. Why Would Anyone Perform This Downgrade

3. Why Target 9.00?

Users often want 9.00 because it was the last major "Golden Firmware" for homebrew.

  • The Exploit: Firmware 9.00 had a kernel exploit that allowed for GoldHEN (Homebrew Enabler).
  • The Current Status: If you are looking for Homebrew, do not downgrade to 9.00.
  • The Better Option: The scene has evolved. Firmware 11.00 (and currently 11.50) are now exploitable using the PPPwn exploit.
    • If you are on a higher firmware (like 10.01), you are likely better off updating to the latest firmware and using the new PPPwn exploit rather than risking a hardware downgrade to 9.00.

Common Failures & Troubleshooting

  • Still getting 1302 after patch: You did not patch the BD firmware version correctly. You must also flash the BD ROM itself, not just Syscon.
  • Error 800-2F-13-0A after downgrade: Your HDD is corrupted. Reformat it to exFAT on a PC before reinstalling.
  • Console won't turn on (Black screen): You shorted the Syscon pins. Remove the wires and check for solder bridges. You have likely bricked the console permanently.
  • Error 900 (CE-34788-9) persists: This means the patch worked, but your USB drive is incompatible with the PS4. Try a USB 2.0 drive under 32GB.

The Hardware Barrier: The Syscon Chip

The primary reason you cannot simply "downgrade" a PS4 by plugging in a USB drive with an older update file is hardware security.

Every PS4 motherboard contains a System Controller (Syscon) chip. This chip acts as the gatekeeper of the console. It stores the console's "lowest firmware version" history. When Sony releases a system update, it often includes updates to the Bleeding Edge secure bootloader.

When you attempt to install a firmware update, the Syscon checks the version number on the USB against the minimum version allowed by the hardware.

  1. The Fuse Checks: The console burns electronic fuses (eFuse) as it updates. Once a fuse is blown for firmware 9.00, the hardware physically knows it has been on that version.
  2. The Downgrade Block: If you try to install a PUP (PlayStation Update Package) file for firmware 5.05 on a console that has already been on 9.00, the Syscon rejects it immediately. The error is usually SU-42118-6 or similar, indicating a version mismatch or a file incompatibility.

4. What About "1302"?

If you genuinely have a console stating firmware "1302" (or similar obscure numbers): The Repair Technician: You have a console with

  1. It might be a Prototype/DevKit: These units work differently and are extremely rare. They use special PUP files.
  2. It is likely a misreading: Ensure you are checking Settings > System > System Information. If it says "10.01", that is standard retail firmware.

Method B: The ESP32 / UART Glitch (WebKit + Kernel Exploit Dependency)

This is even more niche. On firmware 13.02, there is no public kernel exploit. Without a kernel exploit, you cannot access the low-level storage to perform a downgrade. Some developers have theorized using an ESP32 to glitch the bootloader, but as of this article’s writing, there is no working downgrade from 13.02 to 9.00 using this method.

If you see a YouTube video claiming otherwise, it is 100% a scam asking you to download a virus or subscribe to a paid service.

Error 1302 (SU-42118-6) – The Update Loop of Death

This error occurs when your PS4’s Blu-ray drive daughterboard (or the SYSCON chip) has a firmware mismatch with the main system software. You see a message saying: “Cannot start the PS4. Connect a USB storage device containing the update file for reinstallation.”

However, when you plug in a USB with the official firmware, it fails immediately with code SU-42118-6 (1302). This happens because:

  • The BD drive firmware is newer than the motherboard’s firmware.
  • You replaced a broken BD drive without transferring the original daughterboard.
  • You attempted a manual update that corrupted the handshake between the drive and the motherboard.
