Hello I have a PSP 2000 (Has a "Home" button.) that until recently had CFW 5.50 GEN D-3 and accidentally while I was running the Eboot inside the "Update" folder on my PSP (The update is for GEN D-3.) I pressed on
"Install OFW 5.50"... From that time since I'm not even able to run any Eboot that it's on "PSP/GAME" folder and I was wondering if putting a Pandora Battery will fix it.

I want to note that, this PSP had CFW before...
