need help asap

I made a pandora's battery using the soldering method
I then made a magic memory stick but when I put in my memory stick and then put the battery in it starts up by its self and then it will just stay on a black screen until I take the battery out and then it will just turn off.
Much thanks

need more info, how did you make the memory stick? If the Wi-fi, memory stick and power lights all light up, you are on the right track, but may have made the memory stick incorrectly.

I made it with the total newbie easy installer

when you got to the step where you chose what file to put on the psp, what did you select?

ive got the same problem

sounds like you f'd up on the mem stick try and remake it. i had this problem to

I've tried every file
