: A Teensy or Raspberry Pi Pico is often used to interface with the chips.
I must emphasize that I'm providing general information, and you should proceed with caution. Downgrading your PS4 can have unintended consequences, and I disclaim any responsibility for potential damage to your console.
The only proven way to downgrade a PS4 involves complex hardware modification. This process is known as the "Syscon Revert."
The PS4's firmware is regularly updated to add new features, fix bugs, and patch security vulnerabilities. However, these updates can also introduce new vulnerabilities, especially if not properly validated. In Update 1302, a vulnerability was introduced that allows an attacker to downgrade the PS4's firmware. This vulnerability is particularly interesting because it can be exploited by an attacker to gain control over the console, potentially leading to arbitrary code execution.
This hardware-level intervention requires specialized tools. You would need a Teensy++ 2.0 or an ESP32 board, a soldering iron, and high-level soldering skills. Because you are physically modifying the motherboard's data, there is a significant risk of "bricking" the console—rendering it completely unusable—if a single wire is misplaced or a data dump is corrupted.
