Is it possible for my PSP to lose it's downgrade?

If I downgrade my psp with pandora what will I lose the battery or the memory stick ?

• I mean the battery wont be good any more or I have to do something to reuse it ? And the momory stick will I still use it or it wont serve to nothing anymore after pandora thing ?

• Answer:

  its always good to have a spare kit for the modding process. and then when your done just insert your regular battery and memory card back and put your pandora and magic mem away.. the pandora can be used as a regular battery if you have hellcats pandora intaller in your magic memory stick.. or you can just plug in your charger turn on psp then insert pandora battery..
