Well, I have a CFW Slim, and a non-CFW Slim (I know it's hackable, though), is it possible to make a Pandora's battery with a Slim battery and Slim PSP WITHOUT opening the battery (and making it unusable)? Thanks!

 

Possibly if you have a mobo which has EEPROM write access (the earliest slims which came on 3.60 and 3.71 OFW out the box have a TA085 mobo which can write to the battery...everything else can't). Otherwise it doesn't matter what you try it won't work.

 

Ah, thanks so much everyone, Hellcat's did the job, thank you all!
