Historically, when Sony released a mandatory firmware update, reverting to a previous software version (like restoring a factory default state) was widely considered impossible without dedicated hardware flashers (like the Teensy++). The console strictly enforces an anti-downgrade mechanism.
The Syscon (System Control) chip acts as the console's security gatekeeper. It maintains a non-volatile internal token log of the highest firmware version ever installed. If the Syscon detects that the NOR flash is attempting to boot an older firmware than what is registered in its log, it blocks the boot sequence, resulting in a Black Screen of Death (BSOD) or a continuous safe-mode loop.

The Truth About One-Click Software Downgraders
There is no legitimate software-only tool named that can downgrade your console's system firmware . Claims of a simple, automated "v100" tool for downgrading are typically scams or malware designed to exploit users seeking a jailbreak. 🛠️ PS4 Firmware Downgrading (System Revert) Be aware
