Updating PSP from 5.55 to 6.10? Not Possible Officially—6.10 Is Custom Firmware

You cannot officially update a PSP from 5.55 to 6.10 because:

• Sony stopped official PSP updates after 6.60.
• Version 6.10 is not a real Sony firmware—it's a custom firmware (CFW) created by the homebrew community.

If You Want Custom Firmware

1. Understand risks: CFW voids warranty and can brick your PSP if installed incorrectly.
2. Research thoroughly: Use reputable PSP hacking communities and forums for tutorials.
3. Use the correct installer: You'll need a CFW installer tailored to your PSP model.

Always back up your data first. If unsure, consult experienced users or trusted forums.
