Final verdict: The only reliable way to run 9.00 on a PS4 is to buy a console that was never updated past 9.00. No downgrade exists or will likely ever exist for 13.02 → 9.00 due to Sony’s irreversible eFUSE hardware locks.

Downgrading a Go to product viewer dialog for this item. from firmware 13.02 to 9.00 is not possible through software alone and is extremely difficult even with hardware modifications. PS4 security is designed to prevent software-based "reverting" to ensure users remain on the latest version for security and network features. The Quest for 9.00: The "Golden" Firmware
The interest in downgrading to version 9.00 stems from its status as one of the most stable "jailbreakable" versions of the PS4 software. Users on 9.00 can run homebrew applications, customize their interface, and use unauthorized features that are blocked on higher firmwares. Technical Barriers to Downgrading
Anti-Rollback Protection: Sony implements security checks in the system’s Syscon (System Controller) chip to block the installation of any firmware older than the current version.
Hardware Modding Requirements: There is no "USB trick" or simple menu setting to downgrade. To even attempt a revert, you would need professional-grade soldering equipment, a hardware flasher like a Teensy 4.1, and extensive technical knowledge to dump and patch the console's NOR and Syscon chips. ps4 downgrade 13.02 to 9.00
The "Previous Version" Limit: Even with hardware modding, a PS4 can generally only "revert" to the immediately preceding firmware version that was installed on that specific console. If you updated from 12.02 to 13.02, you might revert to 12.02, but jumping all the way back to 9.00 is impossible unless that console was never updated past 9.00 in the past. PS4 Firmware Downgrade: Reverting from 11.02 to 11.00
The story of "downgrading" a from firmware as of April 2026 is one of high-stakes hardware modification rather than a simple software update. There is no software-only "button" to go back; instead, the community relies on a process known as The Core Obstacle: Firmware Slots
The PS4 motherboard contains two "slots" for system software: an active slot inactive slot
When you updated to 13.02, your previous firmware (potentially 13.00) moved to the inactive slot. The Catch: You can only revert to the firmware that was installed immediately
before your current one. If you were on 13.00 before 13.02, you can only go back to 13.00—not all the way to 9.00—unless you have a physical backup of your console's unique data from when it was actually on 9.00. The Technical "Deep Story": How Reversion Works
To force a downgrade, enthusiasts use a method that involves "tricking" the console's security chips: Hardware Interfacing : Users must open the console and solder wires to the (System Controller) chip and the The Teensy/Arduino Bridge : A microcontroller like a Teensy 2.0++ | Question | Answer | |----------|--------| | Can
or a Raspberry Pi is used to "dump" (copy) the data from these chips to a computer. CoreOS Patching : Using tools like PS4 Syscon Tools , the user intentionally corrupts the active firmware slot. The Forced Failover
: When the PS4 detects the corrupted active slot, it attempts to boot from the inactive slot. If that inactive slot was 9.00, the console "reverts." Current Status of 13.02 (April 2026) PS4 13.00, 13.02 & 13.04 HEN Released 30 Jan 2026 —
The current state of PS4 system software 13.02 (released in October 2025) presents a major challenge for the homebrew community. While many users seek to downgrade from 13.02 to 9.00 to access the stable GoldHEN exploit, it is important to understand that a traditional software-based "downgrade" is not possible. Can You Downgrade PS4 13.02 to 9.00 via Software?
No. Sony designed the PlayStation 4 with a "locked" firmware system. You cannot simply install an older version from a USB drive or reset the console to an earlier firmware via Safe Mode. If your console is already on 13.02, it has "blown fuses" (figuratively) that prevent older software from running. The Only Method: Hardware Reversion (Syscon Revert)
The only legitimate way to lower your firmware is through a complex hardware process known as Firmware Reversion. However, even this method has strict limitations:
One-Step Limit: You can generally only revert to the previous firmware version that was installed on your console before the 13.02 update. For example, if you updated from 12.52 to 13.02, you can only go back to 12.52. Write-up date: April 2026
Targeting 9.00: To go all the way back to 9.00 from 13.02, your console must have sat on firmware 9.00 immediately before you updated to 13.02, without any intermediate updates (like 10.00, 11.00, or 12.00) in between.
Required Skills: This is not a software hack; it requires opening the console, soldering a microcontroller (like a Teensy or Raspberry Pi Pico) to the Syscon and NOR chips, and manually patching system files. Current Exploit Status for Firmware 13.02 As of early 2026, the status for PS4 13.02 is as follows:
If your goal is homebrew/backups (jailbreak), you have three paths:
| Path | Feasibility | Notes | |------|-------------|-------| | 1. Stay on 13.02 and wait | Low chance | No public exploit; private exploits may exist but unlikely to release for >1 year | | 2. Sell & buy a ≤9.00 PS4 | Most practical | Market exists for 9.00–11.00 consoles; can find for $200–300 | | 3. Use a different console | Medium | PS3, PS Vita, Switch (V1) are cheaper and fully hackable; PS5 on low firmware is rare |
Important warning: Do not update further. If you are on 13.02 and a future exploit drops for, say, 13.02 or 14.00, updating will lose that chance. But staying on 13.02 is already high; no downgrade possible anyway.
While the main CPU (APU) enforces the rule, the Syscon chip (a smaller microcontroller) holds the truth about your firmware version. Advanced modders have learned to:
