Check official options: Sony does not offer official downgrade paths; verify official support pages or contact support for repair/rollback policies if you have a legitimate need.
Use official updates for stability/security: keep firmware updated to receive security patches, online features, and game compatibility.
Backup data: before any official update or repair, back up saved data to cloud (if subscribed) or external storage.
Use archived compatibility workarounds legally: if an older game requires legacy behavior, look for official re-releases, backward-compatible versions, or ports on PC/other platforms.
Explore sanctioned developer paths: if you’re a registered developer or researcher, pursue official channels (developer programs, responsible disclosure) to work with firmware or security research legally.
Buy used hardware with older firmware: if you need hardware behavior tied to an older firmware for legitimate reasons, consider purchasing an unmodified used console that still runs that firmware — but be aware sellers may have modified devices; check provenance and warranty implications.
Stay informed about policy and law: firmware modification legality varies; consult local laws before attempting modifications.
If troubleshooting: prefer official support, repair centers, or community forums discussing legal, non-exploitative fixes (power cycles, factory reset via official menus, safe-mode official reinstall via USB using Sony-provided files).

Go to Settings > System > System Information.
Look at "System Software Version."
If it says 10.50 or higher, you cannot downgrade.

There is only one functional way to achieve this, known as Firmware Reverting. Method: Hardware Reverting (The Only Legit Way) Check official options: Sony does not offer official

If you are on 10.50 and cannot perform a hardware reversion, you still have options for homebrew in 2026:

Sony uses efuses (electronic fuses) on the console’s motherboard. Every time you update your firmware, the system burns a specific physical fuse inside the Syscon (System Controller) chip. When you try to boot, the Syscon counts how many fuses are blown. If you attempt to install a lower firmware (9.00) than the current fuse count (set by 10.50), the Syscon sees the mismatch and refuses to boot. This is an immutable hardware lock.
