Will Running an ISO on PSP Without CFW Damage It? No – ISO Alone Cannot Brick Stock PSP

ISO Files Alone Cannot Brick a Stock PSP

An ISO is just a disc image. Without Custom Firmware (CFW), the PSP cannot execute unsigned code. It will simply show “Corrupted Data” or ignore the file.

What Actually Risks Damage

• Flashing CFW incorrectly: Power loss during install → semi-brick (recoverable via Pandora battery) or full brick.
• Bad Plugins/Themes: Can cause boot loops (fixable via Safe Mode / recovery).
• Hardware Mods: Hardmods (modchips) risk trace damage.

Safe ISO Usage (Requires CFW)

1. Install CFW (6.61 PRO-C2 / ME-2.3 / Infinity).
2. Place ISO in /ISO on Memory Stick.
3. Launch from XMB or game launcher (IrisMan, PPSSPP not on PSP).

Without CFW

You can only play legitimate UMDs or PSN purchases. ISOs are inert data.
