Can You Enable USB Mode on a PSP with a Broken Screen?
It is not possible to reliably put a PSP into USB mode with a broken screen. Here is why:
User Input Required: Activating USB mode requires navigating the XMB menu and selecting "USB Connection" under Settings. Without a functioning display, you cannot see the menu to confirm the selection.
Navigation Impossible: Even if you memorized the button sequence, you cannot verify the connection status or manage file transfers blindly.
Potential Workarounds
Auto-USB Connection: Connect the PSP to a PC via USB cable. Some firmware versions or custom firmware (CFW) plugins may automatically mount the Memory Stick upon connection without user interaction, but this is not guaranteed on stock firmware.
Video Output: If the PSP's video-out circuitry is intact, connect it to a TV using a component or composite AV cable. This allows you to navigate the menu on an external display.
Data Recovery Advice
Professional Help: If you need to recover saves, photos, or game data, consult a data recovery specialist. They can often read the Memory Stick directly or repair the screen temporarily.
Do Not Force It: Avoid disassembling the PSP unless you have experience with micro-electronics; you risk damaging the Memory Stick slot or motherboard.
A broken screen often indicates impact damage that may affect other components. Professional repair is the safest route for both the device and your data.
