Risk Level: High (Potential for permanent brick)
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.
The phrase "PS4 downgrade 1302 to 900" is a siren song. It promises a way to bypass Sony’s security and unlock the golden age of PS4 jailbreaking (9.00), but for the vast majority of users, it is a fantasy.
You cannot software-downgrade one error into the other. The only proven method—Syscon flashing via a Teensy—requires advanced soldering skills, specific motherboard revisions, and the willingness to permanently destroy your console if you make a mistake.
If your goal is to jailbreak your PS4, keep your console offline on its current firmware (whatever it is) and wait. If it is already on 13.02, either accept it as a stock online console or sell it and buy a 9.00 unit. Do not waste hours on fake tutorials.
And remember: every scam "downgrade tool" you download is just a ransomware or keylogger waiting to happen. Stay safe, stay informed, and respect the fuses.
This article is for educational purposes only. Modifying your console’s firmware violates Sony’s Terms of Service and may result in a permanent online ban. Downgrading via Syscon may also be illegal under the DMCA in your jurisdiction. Proceed at your own risk.

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:
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.
Future Work: Future research should focus on:

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). Last Updated: May 2026 Difficulty Rating: Expert (9/10)
PS4 Downgrade: Is Reverting from 13.02 to 9.00 Possible? The short answer is no, you cannot downgrade a PlayStation 4 from firmware 13.02 to 9.00 using software alone. While you may see videos or websites claiming a "USB update" can roll back your system, these are almost universally scams or clickbait.
Sony's security architecture is designed to prevent firmware rollbacks to block exactly what you are likely looking for: the PS4 9.00 Jailbreak. However, there is a complex hardware-based method known as Firmware Revert, though it has significant limitations. The Reality of "Software Downgrades"
Modern consoles use "fuses" (often called eFuses) that are "blown" during an update. Once a higher firmware is installed, the console's hardware will refuse to boot any older version stored on the hard drive or a USB.
USB Methods: Any site asking you to download a "13.02 to 9.00 Downgrade.pup" file is dangerous and could contain malware.
Factory Reset: Initializing your PS4 from the Safe Mode menu will wipe your data, but it will not lower your firmware version. Hardware Revert: The Only Semi-Solution
There is a legitimate technique called Firmware Revert, but it requires advanced micro-soldering skills and specific hardware.

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.

Downgrading a PS4 from firmware 13.02 to 9.00 is not possible through software alone. While software updates are designed to only move forward, a "revert" is technically possible but requires advanced hardware modification. Key Realities of PS4 Downgrading No Software-Only Method
: Any website or video claiming you can downgrade by simply plugging in a USB drive or visiting a specific URL on the PS4 browser is likely a or "fake". The "Revert" Hardware Method
: The PS4 stores two copies of firmware in its chips (the active and previous versions). A technician can use specialized hardware and to flip the system back to the previous firmware slot. Limitation
: You can only revert to the version you were on immediately before your current one. If you updated directly from 9.00 to 13.02, a revert could work. If you updated from 12.50 to 13.02, you would only be able to revert to 12.50. Alternatives and Status Firmware 9.00
: This is highly sought after because it has a stable, well-documented jailbreak. Current Jailbreak Ceiling
: Public software-based exploits currently support firmware up to
. For versions 11.02 and above (including 13.02), there is no public jailbreak available as of early 2026. Recommendation You cannot software-downgrade one error into the other
: Experts generally suggest selling a console on high firmware and buying a used PS4 that is already on version 9.00 or below. Ps4 Low Firmware - eBay
To downgrade a PlayStation 4 from firmware 13.02 to 9.00, it is important to understand that there is no simple software-only method
like using a USB stick in Safe Mode. A true downgrade is a complex hardware-level procedure known as a Key Reality Check The "One-Step-Back" Rule
: The PS4 stores only two firmware versions: the current active one and the previous one. If your
version was 9.00, a revert is theoretically possible. If you updated from 12.00 to 13.02, you can only revert to 12.00. Hardware Required
: This process requires opening the console and soldering to the chips. It is not recommended for beginners. Safe Mode Limitations : Using a USB in only allows for "Reinstallation" of the firmware; it will reject a 9.00 file if you are on 13.02. Necessary Equipment
If you choose to proceed with a hardware revert, you will typically need: Soldering Tools : A fine-tip iron, high-quality flux, and leaded solder. Hardware Flasher : A device like a Teensy 4.0 Raspberry Pi to read and write to the console's chips. Specific Software : Tools like PS4 Syscon Tools to patch the firmware slots. High-Level Downgrade (Revert) Process Disassembly
: Open the PS4 to access the motherboard. Identify your Syscon chip (it must be a chip, often marked with "A0"-C).
: Use your hardware flasher to create multiple backups of your current NOR and Syscon data.
: Use specialized PC software to swap the active and inactive firmware slots in the data dump. : Write the patched data back to the chips. Initialization
: If successful, the console will attempt to boot into the previous firmware (e.g., 9.00), where you must then perform a full system initialization using a 9.00 Recovery Firmware file from a USB drive. Important Warning
: Modifying your hardware or firmware can permanently "brick" your console and will void any remaining warranties. Many users find it safer and more cost-effective to buy a second-hand PS4 already running firmware 9.00 or lower. Do you have the soldering equipment hardware flasher ready to begin this technical process?
How to Revert the PS4 to a Previous Firmware (Full Tutorial)
It sounds like you're referring to a PS4 error code or firmware downgrade scenario. To clarify:
Common user reviews / community consensus:
Verdict: Not recommended for 99% of users. If you see this phrase online, it’s likely a scam or misunderstanding. Stick to official updates or check PSX-Place / Wololo forums for real downgrade limitations.
Would you like a safer alternative for running homebrew on a compatible firmware instead?
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.
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.
If you genuinely have a console stating firmware "1302" (or similar obscure numbers):
You need to access the SYSCON chip (located near the southbridge) or the BD controller on the motherboard.
Connect your Teensy 2.0++ (flashed with Ps4_Syscon_DeBrick_Tool) to these points.
