Pandora Hack help?

[Golbez]

I have a Phat psp that was from when psp's just came out.  my i recently got a game (final fantasy tactics) and i had to upgrade to play it. well i was a dumb ass and wasnt thinking and i let my gf us my psp. i not knowing that i had to upgrade my psp to play the game i let her use my psp and play the game. well she never told me that she updated it to 3.80 and here i am now trying to downgrade.

i have a spare battery and i removed the 5th pin. but.. i have problems now.

2 things...

1.  When i try to use the mspformat.exe in the cmd.. i get an error and it doesnt format.
  Error:  "Write error"

ive formated the card with my psp and the same thing still happened.  i formated my card with my comp in my computer and in the management menu. still didnt work.

2.  So i thought i would try to run the "Pandora's Battery Firm.installer" and that doesnt work either.  it wont load..
  Error:  "The game could not be started.   (8002014C)"


idk what else to do...

Your probably just not formating the memory correctly or dont know how to use CMD

This is the guide i use to make Pandora batteries. 

Youl be looking at the memory part of course

U cant run Pandoras firm installer without CFW!!!!

exactly what mootoo said
you need a psp that already has CFW in order to create a pandora battery, then you use the created items on your stock psp
