Ps4 Downgrade 1302 To 900

Date Posted: October 26, 2023 Mood: Euphoric, exhausted, and smelling faintly of thermal paste.

Let me set the scene. It’s 2:00 AM. My living room looks like a bomb went off in a Best Buy repair center. Screwdrivers are scattered across the carpet like caltrops. And on my table sits a Glacier White PS4 Pro, blinking its blue light like a dying heartbeat.

On the screen, a warning so cruel it belongs in a horror movie:
"Cannot start the PS4. Connect the DualShock 4 using the USB cable, and then press the PS button." (Error Code: SU-42118-6)

But I knew the real name of this demon. In the underground forums, we whisper it differently: The 1302 to 900 death loop.


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

There is often confusion regarding PS4 firmware version numbers. The number "1302" typically refers to a specific, very early factory firmware version (DevKit/Prototype range) or is a confusion with error codes/Update files. However, most users asking for a downgrade to 9.00 are currently on a much higher firmware, such as 10.00 or 10.01, which is likely where the confusion lies.

As of right now, you cannot downgrade a PS4 from a higher firmware (e.g., 10.01) to a lower firmware (e.g., 9.00) on a standard retail console. ps4 downgrade 1302 to 900

Here is a detailed breakdown of the situation, the methods that do exist, and the reality of the 9.00 exploit.


Sony designed the PS4 with a one-way street for firmware. Inside the console’s Southbridge chip (or Syscon on later models), there is a set of one-time programmable fuses. Every time you update your firmware (e.g., from 9.00 to 10.00 to 11.00 to 13.02), a fuse is physically blown.

When the PS4 boots, it checks the current firmware version against the state of these fuses.

Error 900 (full code: SU-42118-9) literally means: "The update data you are trying to install is older than the minimum required version stored in hardware." Your PS4 is telling you, in no uncertain terms, that you cannot go back.

Error 1302 (full code: SU-42130-2) generally means: "The update file is corrupted, incomplete, or not meant for this region/model." However, in the context of downgrading, it often appears when you try to trick the PS4 into accepting a lower firmware via a modified USB drive or a recovery (PUP) file from the wrong region.

So when you search for "downgrade 1302 to 900," you are actually searching for a mythical process: Take a PS4 that is rejecting a file (1302) and force it into a state where it recognizes an older file (900), then install that older file. In retail consoles, this path does not exist. Date Posted: October 26, 2023 Mood: Euphoric, exhausted,


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:

Here is what it actually takes to force a PS4 from 13.02 down to the holy grail of 9.00 (the last truly jailbreakable firmware):

The process is disgusting: You dump the current NOR chip. You manually hex-edit the firmware version flag from "0x0D02" (13.02) to "0x0900" (9.00). You pray. You reflash the NOR while shorting two specific pins on the motherboard with a pair of tweezers.

If you sneeze during this step, you own a $40 white paperweight.


In the world of console modding, the "Golden Rule" is etched in stone: Never update your firmware if you want a hacked console. Despite this, one of the most frequently searched queries in the PlayStation 4 scene remains how to downgrade a console from a higher firmware (like the 9.00 series) to a lower, exploitable firmware (like 5.05 or 6.72). There are two primary camps of users searching

If you are looking to downgrade a PS4 from a modern firmware to a legacy one, here is the technical reality, the specific risks involving error codes like SU-42118-6, and why the "USB method" is widely misunderstood.

For the uninitiated: You don’t choose to downgrade a PS4 from firmware 13.02 to 9.00. The universe forces you into it.

I had bought a "broken" PS4 off Facebook Marketplace for $40. The listing said: "Won't update. Stuck in loop." What the seller didn't tell me is that his nephew had tried to jailbreak it, botched the update, and left the poor console in a state of quantum purgatory—partially on 13.02, partially convinced it was on 9.00.

For two weeks, I tried the normal routes:

The console was telling me: "I see you are trying to install 9.00, but I have tasted 13.02. I will not go back. I am better than this."
