Read though everything at this link: http://www.pspbrew.com/forum/viewtopic.php?t=485 . Also, make sure when you use the Pack Generator that its going to the root of the psp, which is the little grey drive that may be called Removable Disk L: or something of the sort. The letter may be different. O yeah, and make sure your psp is cleaned back to how it should be originally.
