Well, me and my friend were downgrading our other friend's Slim and we made the Pandora's Battery and MMS with UPMS (Emerald) It failed for some unknown reason and now the memory stick is un-readable by the PSP and it has the battery's Eprom on it. Anyway to get the Eprom off the Memory stick and format the memory stick?

Can you not stick it in your computer or do you not have a card reader?

I fixed it. I toggled USB through recovery mode since the card reader on my computer is broken and it can't do USB through the normal XMB. And formatted the memory stick that way. It's all good now.
