Open the PS4 to access the motherboard.
Gather your tools. This includes a micro-soldering station, a Teensy microcontroller, a breakout board for the Syscon chip, wires, resistors, a computer, and the latest versions of PS4 Wee Tools and PS4 Syscon Tools.
A is a specialized piece of software or hardware used to revert a PlayStation 4’s system software to a lower version. While Sony officially prohibits downgrading to prevent piracy and maintain security, the practice is popular among the homebrew community for accessing jailbreakable firmware versions, such as 9.00 or 11.00. Core Concepts: Reversion vs. Downgrading
The TNC method involves soldering a tiny microcontroller to the PS4 motherboard. This microcontroller can backup your current NOR/Syscon, and then, upon user command, flash a patched, older version of the firmware directly into the NOR chip. Technicians comfortable with soldering.
Sony protects the PS4 firmware using cryptographic keys. The console will reject any official or unofficial update file that is lower than the currently installed version. A software program running on your PC or your PS4 cannot bypass this digital signature check. The Danger of Fake Tools
