Can You Update a PSP Using a UMD? (No – Only Network or Memory Stick)

No. UMDs (Universal Media Discs) store only games and movies. They cannot carry or execute system firmware updates.

Why UMDs Can't Update Firmware

• Firmware lives on the PSP's internal NAND flash, not removable media.
• The update process verifies cryptographic signatures only via Network Update or Memory Stick PSP/GAME/UPDATE/EBOOT.PBP.
• UMD drive firmware is separate and updated automatically by the system firmware.

Correct Update Methods

1. Network Update: Settings → System Settings → System Update (via Wi-Fi).
2. Memory Stick: Download EBOOT.PBP from Sony → PSP/GAME/UPDATE/ → Settings → System Update → Update from Memory Stick.

Never attempt to burn firmware to a UMD—it will not work and may damage the drive.
