During certain troubleshooting situations, it may be necessary to restore all of the PSP system settings back to their original "default" configuration.
Restore Default Settings
The Restore Default Settings feature will erase any previously saved settings and restore all of the settings to the default. The system's firmware will remain as the current version.
From the XMBTM home menu, go to (Settings) > (System Settings) > [Restore Default Settings].
The message "Do you want to restore the default settings?" should appear. Select "Yes" and press the button.
You will then see a message, "All settings will be returned to default settings. Are you sure you want to continue?" Select "Yes" and press the button.
All settings are now restored and the system password is reset to "0000".
Press the button to restart the system.
- Re-enter system settings as appropriate.
