    That means you did not modify the battery right. I think people have been having troubles of not scrapping the line off completely

    I should think that i've followed instruction to make a pandora battery step by step. I've cut the one the corner connection of the IC (i guess you know what i meant). It did not work.

    I've even cut the line as suggested in one of the posting. Stetp by step.

    Yet my PSP does not go to recovery mode.

    I've downloaded almost all cracked updated as suggested.

    But STILL my PSP did not get to the RECOVERY mode.

    Anybody with other brilliant ideas. Please , I am in desperation to start playing my PSP rather than just listen to song from a very expensive MP3 player
