Well, before I may continue, I have a few questions also.

I already have the Pandoras Battery from a PHAT PSP, will it still work on the slim?
And second, I tried using the tutorial I found, bu it did not help me.
It just ended up bricking the psp ):

use this program: Pandora CMD Front End you need the 1.5 , 3.71 and 3.8 frimwares also though.


this program makes it really easy to fix a brick.

it makes the magic memory stick, then you just put it in, then the battery, hit x and your good to go. just rember to reset your psp between steps when it tells you to.

you get the official firmwares, name them 150, 371, and 380. go to the install folder ex.:C:\Program Files\Pandora_CMD

you put 150 in the C:\Program Files\Pandora_CMD\root folder
you put 371 in the C:\Program Files\Pandora_CMD\root_371
you put 380 in the C:\Program Files\Pandora_CMD\root_380

run the program and follow the steps 1 by 1
