Do you have any with console hardware modifications or soldering? What specific homebrew features are you trying to get?
: You can only revert to the firmware version that was immediately installed on the console prior to the current update. If your console went from 9.00 to 10.00, and then to 13.02, the backup slot contains version 10.00, making a downgrade to 9.00 impossible.
Because 9.00 is so popular for homebrew, many fake "downgrader" tools exist online.
However, you can achieve a firmware downgrade using a precise hardware-level modification known as a , provided your individual console was updated directly to 13.02 from version 9.00. This comprehensive guide breaks down the core concepts, hardware requirements, and step-by-step realities of managing custom firmwares.

is not possible through standard software or system settings. Sony uses security measures and a "syscon" chip to prevent users from reverting to older firmware versions, primarily to prevent piracy and maintain system integrity. ftp.bills.com.au Why Downgrading is Restricted Anti-Rollback Protection
: Modifying specific bytes of data using dedicated software tools to manually tell the console to read from its previous firmware slot.
You use a computer to read and extract the raw binary data (the "dump") from both chips. Do you have any with console hardware modifications
: Find the Serial Peripheral Interface (SPI) Nor Flash chip and the Syscon chip on the board.
As of mid-2026, the jailbreak community has established an exploit methodology known as . This exploit repurposes data structures from the legacy PlayStation Vue media application to run homebrew code.
Understanding PS4 Firmware: Can You Downgrade from 13.02 to 9.00? If your console went from 9
Suggest that is already on a lower firmware.
However, while a conventional downgrade is impossible, the reality for those with advanced technical skills is more nuanced. Under very specific circumstances, which are highly unlikely for someone who has already updated to the latest version, a "firmware revert" to a previous version is theoretically possible. Let's break down exactly what that means, why it's almost certainly not an option for you, and what your actual alternatives are.
: You can only reach 9.00 if your console was running 9.00 just before the most recent update, which is highly unlikely if you are currently on 13.02. Technical Requirements
Sony patched these specific kernel vulnerabilities in version 9.03 and all subsequent versions, up to the current 13.02 release. The Core Technical Barrier
