Some slim with cfw nowadays cannot convert batteries to pandora due to SCE attempt to pandora proof a psp. In order to verify that a slim psp with cfw is capable of creating pandora battery you must install a homebrew app named PSPident by jas0nuk compatible only for 3.xx cfw (it identifies what version & type of motherboard installed on your psp slim (NOTE: if your PSP is detected as a TA-085 v2/TA-088, it's one of the newest Slim revisions which cannot write to the battery serial and therefore cannot be used to create a Pandora battery!

installation notes:
Please read the README.txt file, copy the PSPident folder to your GAME/GAME3XX folder and run it
hope this helps!
