Uhm, don't go through that trouble, just at the pandora battery creator read the options. One option will say "convert to service mode" and "convert battery into normal one". You need to click the convert to service mode one to make a pandora but once you downgrade his PSP don't delete what's on the memory stick. Now put ur charger in YOUR PSP and take the battery out. Now start. Now go back to pandora battery creator, and slip your battery in. Now press [] to convert into normal battery. There's another, slightly more complicated process by dumping your eeprom.bin but I suggest my method.
