Downgrading a console's firmware means reverting to an earlier version, which can be useful for several reasons.

For gamers, it can provide a way to play older games or use older exploits that are no longer available on newer firmware versions.
Sony designs the PS4 to prevent users from reverting to older firmware to protect the system's security and prevent piracy. Software Downgrading: ps4 downgrade tool

In 2016, a group of hackers and developers, known as "Specter," released a PS4 downgrade tool that exploited a previously unknown vulnerability in the console's firmware. This tool, also known as "Downgrade Tool" or "PS4 Downgrader," allowed users to downgrade their PS4's firmware from a newer version (e.g., 4.05) to an older version (e.g., 2.76 or 3.55).
