okay, heres what happened. i bought a datel pandoras battery maker from code junkies.com. i made the batery and mem stick and installed cfw. i started messing around with themes and finally found one i liked. but, then i upgraded to 3.90m33 and none of my games or apps worked. so, i tried to use a downgrader and it said to replace custom themes with the original before using it. so i did that. but, now my psp wont work. i bricked it pretty bad. i cant even get in to service mode. the green light turns on for a minute then shuts off. also,(before all this happened) i tried to install time machine(cause i had no idea what it did) and i accidently messed up my battery. now it wont convert to a pandoras. any ideas? thanks.
Also, when i convert it to a pandoras, all it does is it automatically turns the psp on when i insert the battery, but all it does is the green light comes on for a minute then it shuts off. would getting a new battery help? or do i need a new motherboard? thanks.
