Problem with my PSP

Everytime I turn on my PSP it goes straight to these options: Press x to install 3.80 M33, o for 3.80, etc. I chose to install 3.80 M33 but this happens all the time when I turn on the psp. It goes straight to the options menu.

IDK, take your ms and battery out and power on using the charger. Use that Pandora tool to de-pandora your battery.

haha ya dude you never un-pandora'd your Battery, you gotta do what Roxfox said and turn it on with just the charger and then put that thing back to normal.

Same with the mem stick...you'll need to delete the files that load the pandora program.
