Videos showing a UI transitioning from a high firmware to a low firmware are easily faked using edited video footage or web-browser dev tools on a local network test kit. Real Hardware Tools Used by Professionals
Downgrading typically requires initializing (formatting) the hard drive, deleting all games and data.
Sony constantly patches security vulnerabilities with new system updates. The PlayStation modding community relies on these vulnerabilities to run custom themes, game mods, backup managers, and Linux. If a console accidentally updates past a exploitable firmware version (such as 9.00 or 11.00), a hardware downgrade is the only way to restore jailbreak capability.
