if someone would be able enlighten me on this situation it would be much appreciated. so, i had a v.2.81, updated it to v.3.03, nows where i sort of get lost.. are you supposed to completely remove the old psp file? well thats what i did, then i did the downgrade i think..(the zip folder has ms_root, src, etc.) so i copied the psp folder out of the ms_root. did the gta thing.. my system sais its running 3.03 HEN.. and i put the the 1.5 eboot (changed the name to update.pbp) in the new psp/game/update folder... it says in the menu, PSP update ver X.YZ, so i click it, it says doing preperations, goes blue, then the screen comes up and says "extracting special prx's from pbp, then says, cannot locate UPDATE.PBP, then it restarts. sorry this was so lengthy but i just wanted to give a detailed description of the situation. if someone could tell me what to do that would be awsome.
