    Buy a pandora battery and magic memory stick online.
    The only way to downgrade that firmware is to use pandora batt and mms.
    What psp model do you have fat or slim?

    you cannot downgrade any 4.00+ official slims. you will have to wait for a new universal unbricker.

    You have the new TA-088 cpu that is unhackable. Dark Alex has not come up with a update yet. You'll have to wait for now or return it for something else.
