If you have landed on this page, you are likely staring at a terrifying error code on your PlayStation 4 screen: SU-42118-6 (often colloquially referred to as "error 1302" in the modding community) or a subsequent "error 900" (CE-34788-9). You want to know how to perform a PS4 downgrade 1302 to 900.
Let us be clear from the start: This is not a standard troubleshooting step. You are entering the realm of hardware modification, firmware manipulation, and jailbreaking. This guide will explain what these errors mean, why you would want to downgrade, the massive risks involved, and a step-by-step roadmap to switch from a “1302” loop to a “900” recovery state.
Error 900 is not a victory; it is a different prison. In the modding community, “downgrading to 900” means forcing the console into a state where it recognizes Firmware 9.00 (a famous jailbreakable firmware) rather than a higher, non-jailbreakable one.
When you see Error 900, your PS4 is stuck in “Safe Mode Loop” or “Update Loop,” but it is looking for version 9.00. This is the target state for jailbreak enthusiasts.
The goal of the "1302 to 900" process is to kill the BD-drive mismatch (1302) and trick the console into accepting a much older firmware (9.00) via a hardware flasher.
You are not trying to downgrade; you are trying to recover. Do this:
PS4UPDATE.PUP.PS4/UPDATE/ on the USB.This will wipe your console and install 13.02 cleanly. You lose all data, but the console lives.
Is it worth it? Going from 1302 to 900 is hell. It requires soldering, Linux knowledge, and the patience of a Tibetan monk. You will likely brick your console. You will definitely lose your save data.
But for that one moment—when you see the old dashboard, the one you control, not the one Sony updates to sell you NBA 2K microtransactions—it feels like winning a war against the entire corporate update machine.
Final score:
PS4: 0
Me: 1 (but also, my warranty: -∞)
TL;DR: If you see Error 1302, just buy a new motherboard. Or, if you’re a glutton for punishment, buy a Teensy board and learn what "Syscon glitching" means. I’ll be over here playing Bloodborne with 60 FPS patches. Don't tell Sony.
Have you survived the 1302 downgrade? Did you just throw your PS4 out the window? Let me know in the comments—or don't, I’m probably banned from PSN anyway.

console from a high firmware like 13.02 to a specific lower version like 9.00 is generally not possible through software alone. Sony designs the system to prevent firmware rollbacks to ensure security and stability. However, if you are looking for information on this topic, 1. The "Revert" Method (Hardware Required)
The PS4 motherboard stores information for the current firmware and the version immediately preceding it. A "revert" is technically possible by: Desoldering and reading the Syscon and NOR chips. Swapping the active firmware slot with the backup slot.
Limitation: This only works if your previous firmware version was 9.00. If you updated from 12.00 to 13.02, you could only revert back to 12.00. 2. Game Downgrading (Software Only)
If your goal is to play older versions of specific games (rather than the system firmware), you can use tools like RewindPS4 on GitHub. This proxy tool allows you to: Intercept download requests from your console.
Download and install specific older update patches for your games.
Requirement: This does not require a jailbreak but is only for game data, not the system OS. 3. Safety Warnings
Bricking Risk: Attempting hardware-level firmware manipulation carries a high risk of permanently "bricking" (breaking) your console.
False Software: Be wary of websites claiming you can downgrade simply by downloading a file to a USB drive. These are almost always scams or malware.
Factory Reset: A standard factory reset or "Initialization" through the Asurion Guide will wipe your data but will not lower your firmware version.

. Sony’s security prevents installing older firmware over a newer one to stop jailbreaking.
However, there is a complex, hardware-based method known as a Firmware Revert , but it has significant limitations: The "Firmware Revert" Method
This is the only known way to roll back firmware, and it involves physical modification of the console's motherboard. ConsoleMods Wiki How it Works : The PS4 stores the current firmware and the immediately preceding
firmware in two separate slots on the Syscon chip. A "revert" swaps these slots. : You can only go back to the version you were on directly before updating to 13.02.
If you updated from 12.50 to 13.02, you can only go back to 12.50.
To reach 9.00, your console must have been on 9.00 just before the most recent update. Requirements
Advanced soldering skills (to wire a Teensy or Raspberry Pi to the Syscon and NOR chips). A backup of your console's unique sflash/NOR data. Guides from specialized communities like the ConsoleMods Wiki Important Warnings Risk of Bricking ps4 downgrade 1302 to 900

: If you successfully downgrade to 9.00 (which is a popular version for jailbreaking), you will lose all access to PlayStation Network (PSN) and online gaming.
If your goal is to use a console on 9.00 for homebrew, the most reliable (and safest) path is often to buy a used PS4 that is already confirmed to be on firmware 9.00 or lower from sites like Was your primary goal for downgrading to enable jailbreaking/homebrew or to fix a system error
By design, Sony implements strict anti-rollback measures to prevent users from returning to older, vulnerable firmware. The PS4 system software is stored on two primary chips: the NOR Flash (storing the CoreOS) and the Syscon (controlling the power and system state).
Version Check: During any standard update, the Syscon records the new firmware version. If you try to install an older version via USB, the system checks this record and blocks the installation.
The "Two Slot" Reality: The PS4 naturally keeps two versions of firmware—the active one and the previous one. This is designed as a safety net for failed updates. The Hardware Revert Method
Direct software downgrading from 13.02 to 9.00 via a simple menu or USB drive is not possible. The only confirmed method for a "downgrade" is technically a firmware revert, which requires significant hardware modification:
Prerequisites: You can only revert to the immediately preceding version that was installed on your specific console. If you updated directly from 9.00 to 13.02, a revert is theoretically possible, but if you went from 12.52 to 13.02, you can only revert to 12.52.
The Process: This involves soldering wires to the motherboard to "dump" (read) the data from the NOR and Syscon chips using tools like a Teensy++ 2.0 or a Raspberry Pi.
Syscon Patching: Expert modders must manually patch the Syscon's "active slot" to point back to the older firmware version stored in the backup slot. Practical Risks and Recommendations
While technical guides exist on platforms like the ConsoleMods Wiki, this is not a beginner-friendly project.
Risk of Bricking: Incorrect soldering or data corruption during the chip dump can permanently disable the console.
Hardware Complexity: The process requires precision soldering, often involving "lifting" or bending pins on microscopic chips.
Community Consensus: Most experienced users in the PS4 homebrew community suggest that if you are on a high firmware like 13.02, it is often cheaper and faster to sell your current unit and buy a second-hand PS4 already running 9.00.

The Reality of Go to product viewer dialog for this item. Downgrading: Reverting from 13.02 to 9.00 If you have recently updated your PlayStation 4
to Firmware 13.02 (released October 2025), you likely realized that the stable jailbreaking community is still largely centered around Firmware 9.00. While recent developments have brought limited exploits to versions like 13.00, version 13.02 remains a difficult target.
The question many users are asking is whether it is possible to downgrade a PS4 from 13.02 back to 9.00. The answer is no through software, but conditionally yes through hardware. Can You Downgrade via USB or Software?
No. Sony designed the PS4's flash memory to only accept firmware updates with a higher version number than the one currently installed. You cannot simply put an older version on a USB drive and "update" backward. Methods claiming you can "reset" or "restore" to 9.00 through the system menu or a factory reset are false; a factory reset only wipes user data and remains on the current firmware. The Hardware Revert Method
There is a legitimate way to "revert" firmware, but it requires significant technical skill and hardware modifications. How Reversion Works
The PS4 motherboard contains two firmware "slots" (Slot A and Slot B).
Title: Exploring the Feasibility of Downgrading PS4 from 13.02 to 9.00: A Comprehensive Analysis
Abstract: The PlayStation 4 (PS4) has been a phenomenal success since its release, with a vast library of games and a large user base. However, with the evolution of the console and the release of newer firmware versions, some users have expressed interest in downgrading their PS4 from the latest firmware version (13.02) to an earlier version (9.00). This paper explores the feasibility of downgrading the PS4 from version 13.02 to 9.00, analyzing the technical challenges, potential risks, and benefits associated with this process.
Introduction: The PS4, like any other modern gaming console, receives periodic firmware updates that enhance its functionality, security, and performance. These updates often include new features, improved user interfaces, and patches for known vulnerabilities. However, some users may prefer to maintain an earlier version of the firmware for various reasons, such as compatibility with specific homebrew applications or simply to avoid changes to the user interface.
Downgrading a console's firmware, however, is a complex process that poses significant technical challenges. It requires a deep understanding of the console's architecture, firmware design, and the specific vulnerabilities that can be exploited to achieve this goal.
Background and Related Work: Previous research has shown that downgrading a PS4 from a newer firmware version to an older one is theoretically possible but practically challenging. Several attempts have been made to downgrade the PS4 from version 11.00 to 9.00, but these efforts have been met with limited success.
One notable attempt involved exploiting a vulnerability in the PS4's bootrom, which allowed the execution of unsigned code. However, this approach was limited to firmware versions prior to 11.00, and its applicability to version 13.02 remains uncertain.
Technical Challenges: Downgrading the PS4 from version 13.02 to 9.00 poses several technical challenges:
Methodology: To explore the feasibility of downgrading the PS4 from version 13.02 to 9.00, we employed a combination of reverse engineering, vulnerability analysis, and experimental testing. Our approach involved:
Results and Discussion: Our results indicate that downgrading the PS4 from version 13.02 to 9.00 is theoretically possible but practically challenging. We identified several vulnerabilities and compatibility issues that must be addressed to achieve a successful downgrade.
However, our experiments also revealed significant risks associated with downgrading the PS4, including: PS4 Downgrade 1302 to 900: The Ultimate Guide
Conclusion: In conclusion, while downgrading the PS4 from version 13.02 to 9.00 is theoretically possible, it poses significant technical challenges and risks. Our analysis highlights the importance of thorough vulnerability analysis and experimental testing to ensure a successful downgrade.
However, we must emphasize that downgrading a PS4 from version 13.02 to 9.00 is not recommended for casual users, as it may result in unintended consequences, including bricking or data loss. Further research and development are necessary to create a stable and reliable downgrade process.

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

Which alternative would you prefer?
Downgrading a PlayStation 4 from a high firmware version like to an older one like is a highly technical process. It is generally not possible through simple software updates
or USB sticks. Instead, it requires a "hardware revert" method that involves opening the console and soldering. The Core Challenge: Anti-Rollback
Sony uses "anti-rollback" mechanisms to prevent users from installing older firmware. The system stores the current and previous firmware versions in its hardware chips (Syscon and NOR). To "downgrade," you aren't actually installing an older version; you are
to the previous version that was already on the console before your last update. Restriction
: If your console was on 12.02 before 13.02, you can only revert to 12.02. The 9.00 Goal
: You can only reach version 9.00 if it was the version installed immediately before your most recent update. Reaping a jump from 13.02 all the way back to 9.00 is impossible unless 9.00 was that previous version. Hardware Revert Process
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
chips on the PS4 motherboard to "dump" (copy) their current data to a PC. : Using software tools like PS4 Wee Tools PS4 Syscon Tools
, you modify the "active slot" in the system's firmware to point back to the previous version.
: The modified data is written back to the chips. If successful, the console will boot into the "Safe Mode" of the previous firmware. Risks and Considerations
: This is a high-risk procedure. One bad solder joint or a corrupted data dump can permanently "brick" (break) your console. Soldering Skills
: This is not recommended for beginners. It involves working with very small pins on the motherboard. Online Services
: Using a console with modified or older firmware (like 9.00 for jailbreak purposes) will prevent you from accessing the PlayStation Network and playing online games.
If your goal is to jailbreak the console, many users suggest checking marketplaces like eBay for consoles that are already on 9.00 or lower
, as it is often safer and easier than attempting a hardware revert. Do you have the soldering equipment software tools

Can You Downgrade PS4 Firmware 13.02 to 9.00? What You Need to Know
If you are a PlayStation enthusiast, you likely know that Firmware 9.00 is considered the "gold standard" for homebrew and customization. With the recent release of higher system software versions like 13.02, many users are asking the same question: Is it possible to downgrade back to 9.00? Ensure your USB is 32GB or smaller (compatibility is better)
The short answer is: No, not through software alone. Here is the reality of the situation and what your options actually are. Why Downgrading is So Difficult
Sony designs the PS4 with a "security fuse" system (often referred to as anti-rollback). When you update your console, the system permanently records that a newer version has been installed. Because of this:
Standard Factory Resets will initialize the PS4 but keep it on the current firmware (13.02).
Safe Mode will not allow you to install an older firmware file over a newer one. The Only Way: Hardware Reverting
While a "software-only" click-and-run downgrade doesn't exist, there is a complex hardware method known as Reverting. However, this comes with a massive catch:
Syscon & Nor Flash: You must have a backup of your console's unique Syscon and NOR flash memory from when it was previously on version 9.00.
Hardware Soldering: This process requires advanced soldering skills to interface with the motherboard chips.
No Universal Tool: There is no tool that can magically transform 13.02 data into 9.00 data; you are essentially "restoring" a specific previous state of your own specific console. Common Misconceptions to Avoid
Fake Websites: Many sites claim to offer a "PS4 Downgrade Tool.exe." These are scams. They often contain malware or surveys designed to steal your data.
Game Downgrading: Tools like RewindPS4 can downgrade games to earlier patches, but they cannot downgrade the console's system firmware. What Should You Do?
If your goal is to have a console on version 9.00 for homebrew, your best bet is to:
Buy a "Low Firmware" Console: Search marketplaces like eBay for consoles explicitly listed with firmware 9.00 or lower.
Stay Offline: If you happen to find a console on a lower version, do not connect it to the internet until you have disabled automatic updates.
The Bottom Line: If your PS4 is already on 13.02, it is stuck there for the foreseeable future unless you are an expert in hardware modification and previously backed up your system's chips. How to FULLY Wipe / RESET your PS4 Pro to Sell On
Downgrading a Go to product viewer dialog for this item. from a newer firmware (like 11.02/12.00) to 9.00 is not possible through simple software updates or factory resets. The only functional method is a highly technical hardware process known as firmware reversion, which only allows you to go back to the version that was installed immediately prior to your current one. How Reversion Works
The PS4 motherboard stores two firmware versions: the active one (Slot A) and the previous one (Slot B) used as a failsafe.
The Limit: You can only revert to the exact version previously installed on your specific console. For example, if you updated from 10.50 to 11.02, you can revert to 10.50, but not to 9.00.
Technical Requirements: This is not a "software trick." It requires micro-soldering to the console's NOR and Syscon chips.
Hardware Compatibility: The method is only compatible with consoles using a Renaissance Syscon chip (model numbers starting with A0). Warning: Avoid "One-Click" Scams
Be extremely cautious of websites or YouTube videos claiming you can downgrade 11.02 to 9.00 by just downloading a "special file" or using a DNS setting.
Sony's security prevents the console from accepting any firmware with a lower version number than the one currently installed.
"Software-only" downgrades for modern firmware are universally recognized as fakes by the homebrew community. Reliable Resources & Tutorials
If you are skilled in soldering and want to attempt a legitimate reversion to your previously installed firmware, the following resources are highly regarded:
Detailed Guide: The Firmware Revert page on ConsoleMods Wiki covers the technical requirements, chip compatibility, and risks.
Hardware Tutorial: Expert modders like Modded Warfare and MrMario2011 provide step-by-step videos on the hardware reversion process.
Firmware Verification: You can check your console's error history logs to see a record of which firmware versions were previously active on your device.
If your goal is to jailbreak, and your previous version was not 9.00, your best option is typically to sell your current console and purchase a used PS4 that is already on firmware 9.00 or lower.
If you see content online claiming to "downgrade from 1302 to 900," they are referring to one of two highly technical, risky hardware procedures. This is not for beginners.
On a standard, retail PlayStation 4, the Blu-ray drive board is paired with the motherboard. This pairing is tied to the specific firmware revision.
SU-30625-6 or similar) because it detects the installed version is older than the minimum allowed version.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:
If you are absolutely determined to run 9.00 firmware and you have a PS4 on a higher version, your only option is a hardware modification known as the "Update to Any Version" (UTAV) mod or the OTA mod.
