Flash0 Mess Up

I Semi-Bricked My PSP By Trying To Change My Flash0 Theme And I Guess Some Files That Didn't Need To Go Anywhere Got Deleted, And I Can Access My Recovery Menu And I Can Boot Into XMB (Though I Can't Access My Memory Stick But I Can Boot My UMD) I Tried To Load The PSP/GAME/RECOVERY Eboot But When I Tried To Load The Recovery Pack Thing, I Said This Game Could Not Be Started. So I Guess If I'm Able To Load Into Recovery And Access XMB, I Should Be Able To Restore With Pandora And The Universal Unbricker Right? Or Any Other Solutions? BTW I Have 3.90 m33-2

Ok, I Have It Somewhat Fixed, I Found A New Flash0 Theme And Added Its Content To The PSP, I Can Now Open My Eboots, But It Will Freeze If I Attempt To Open Pictures, Movies, Or Music. What Do I Need To Do To Fix That?
