The only "tool" that ever worked for downgrading was called "PS4 Downgrader" by a developer named – but that was for firmware 1.76 on the original PS4 (2014 era). For modern firmware, there is nothing.
: Sony uses a "Syscon" chip and "NOR" flash that store the current and previous firmware versions. Software alone cannot bypass these hardware checks. ps4 tool downgrade v100 exe download work
: The PS4 stores only the current firmware and the immediately preceding version on its Syscon chip. A Windows .exe tool cannot bypass these hardware-level security checks.

Downgrading a PS4 is possible, but it requires advanced hardware modification. It is not an automated software process. Developers like Bguerville have proven that you can revert a PS4 to a previous firmware version, but only under strict technical conditions. The Syscon and NOR Flash Method
You have to solder directly to the Syscon chip to downgrade it, and sometimes the NOR chip to rewrite the firmware.
The process involves micro-soldering wires to the PS4's NOR and Syscon chips, and sometimes "lifting" specific pins to glitch the system into a debug mode.
The following are real tools developed by the PS4 community for specific tasks, including game downgrading and advanced hardware interfacing. They are often open-source and available on platforms like GitHub.
