Major help here, working on it for 3 hours already....

i had cfw 3.90-m33, and upgraded to the new ofw 4.01. and then realized i needed to borrow my friends pandoras battery again to get back to cfw (same battery we used to downgrade it before). and now i did my mms and use pandoras batt. and nothing happens. the battery doesnt even start up. it worked the last time we used it, but i can have the battery in, and the charger connected and it wont show that it's even IN the psp..... i really need help, im beyond frusteration here..... thx in advance.......[edit: do i need a new pandora's battery or something?]

Chances are, you probably did something wrong while making mms.
You can try to re-do steps on mms and maybe that should work.

i've re tried it more than 20 times.....using different methods too. i'll give it ONE last try before i buy datel TOOL battery.....

Unless he reversed the pandora's battery back to normal, then you should just like stick the battery in then stick the mms in and it should work. Or it might be the other way. Try both, sticking them in, in a different order. Or try leaving the charger out.

edit: tried new installer and it works. thx anyways
