HELP me hack a PSP 2000!!!!!!

Hi well I have my bros psp slim and I try downgrade it with a pandora battery that I made with my psp 1000. But it didnt work. I think I did everything right though because I made a magic stick for his slim and when put the pandora in and hold the trigger button it stayed in a black screen with green light and no ctf pop up. When I tryed it on my psp 1000 it worked fine the ctf pops up then I can install it. His psp 2000 is ofw 5.51. He got it when It first came out with the Dexer bundal with family guy umd with it. He updated sometime in june. Is there anyother way to hack his psp without a pandora..Or better yet what I did wrong with the pandora.:sad:

y not just buy pandora, they're not that expensive

I already made a pandora battery...Idk why it isnt working with this psp 2000

it's got to be battery or memory stick, try reinstalling the files onto the magic memroy stick

I did... I try like 3 times with the pandora battery....I downloaded the 5.00m33-4 install to put in my magic stick...the install for it wont pop up!!I hold the trigger button for a while and nuttin pops up..when i tryed on my 1000 it work fine..

Not that I know of. We all did it with pandora.
Some buy it, but it my case, i made it myself, thats an option too
