btw, nice guide!
Hey guys. I'm trying to unbrick a Slim PSP with a Pandora battery of a fat PSP.
In Part 4, where it says
Place the folder named 'RSPsarDumper' in 'X:/PSP/GAME/'.
Run it from GAME > Memory Stick.
I'm getting an error while loading 'lib.prx'. I saw some other people in this thread having the same problem, and they skipped the step. Do I just move on and use the battery right away? Because there's nothing else left to do in the guide. I know I'm doing something wrong, but I don't know what... I've inserted the Pandora into the slim PSP, holding square to install 3.40-OE, but the screen remained black.
