PPPwn is a kernel exploit that works on PS4 firmwares up to 11.00. However, while the exploit chain exists, . Even though tools like PS4JbEmu support a FW=1050 configuration, functional payloads (like GoldHEN) are not available for this version.
Solder your flasher to the NOR (BIOS) and Syscon (System Controller) chips on the motherboard to extract their data.

💡 If this sounds too complex, the most common community advice is to sell your current console and buy a used PS4 that is already on firmware 9.00 or lower. ps4 downgrade 10.50 to 9.00
Some methods require you to be on a lower firmware to install tools that allow downgrading.
: The most severe risk is permanently disabling your console. If you damage the Syscon or NOR chip beyond the ability to read and write, or if you're unable to write back original working dumps, your PS4 may become completely unusable.
Your PS4 was on 9.00, and you updated directly to 10.50. A downgrade to 9.00 is theoretically possible . PPPwn is a kernel exploit that works on
This process involves microsoldering and manipulating the PS4's core hardware (Syscon and NOR flash). If done incorrectly, you can permanently damage your console (brick it).
The PS4 stores two firmware versions on its motherboard: the active one and the previously installed one. You can only revert to 9.00 if 9.00 was the very last firmware version you had installed before updating to 10.50. Hardware Required:
Before diving into the downgrade process, it's important to understand why firmware 9.00 is so highly sought after among the PS4 modding community. As of 2025, version 9.00 remains the last fully exploitable firmware for the PS4, featuring a mature and stable jailbreak ecosystem. Solder your flasher to the NOR (BIOS) and
The PS4 stores its firmware in two distinct slots on the motherboard: Slot A (the active firmware slot) and Slot B (the backup slot). This dual-slot arrangement acts as an update failsafe. Part of the firmware resides in an encrypted, soldered chip on the motherboard that tracks the installed firmware version and actively prevents the installation of lower firmware versions. This means you cannot simply download an older firmware file, put it on a USB drive, and install it through Safe Mode - the PS4's security checks will reject it.
There is one special case worth mentioning: . If your PS4 is running a beta version of system software, you may be able to revert to the previous stable version. For example, if you installed a 10.51 beta, you could potentially go back to 10.50. However, this still does not enable going from a beta directly to 9.00.
The main reason to downgrade your PS4 from 10.50 to 9.00 is to enable the installation of custom firmware, also known as CFW. CFW allows users to run homebrew applications, play games from other regions, and even exploit vulnerabilities in the system. The firmware version 9.00 is particularly popular among developers and enthusiasts because it provides a relatively stable and secure environment for experimenting with custom code.
For many PlayStation 4 enthusiasts, firmware represents a walled garden—a stable, yet restricted environment where homebrew, custom themes, and backups are impossible. Conversely, firmware 9.00 is considered the "golden ticket," offering a stable, reliable jailbreak.
