Pandora Batter Fails To Work

My Slim PSP wont run my (LEGALLY OWNED NON PIRATED) isos anymore. I think it is due to me downloading the Rock Band Unplugged Demo, and I hear it has a cfw iso disabler. I formatted my memory stick and the isos show up now, but i cant run them so i was going to re-hack the psp so it will be fresh. I pop in my Pandora and it doesn't work....

So I reinstalled Despertar del Cementerio and still no luck.

Pics of my: psp, mms(1gb one) and 2 other regular mem sticks and my Pandora battery.

And yes I really legally own the isos. I ripped my umd for faster loading times.
