my sig has many of the questions answered, look at the tutorial, and you WILL need a USB cord to do most modding, unless you can download files from your psp, try to find an winrar for the psp, then use pspfiler to switch it al around, but that will take forever, if your psp will EVEN let you download the file...
u need to use the USB to do backup of flash... thats why you need 3.03 oe-c or above!
