    do u have the 1.50 update in the PSP\GAME\UPDATE folder named as UPDATE.PBP....u might be better off using an easy installer type application.

    um no. thats alot of info. whatever u downloaded came with a readme...it walks u thru it step by step. or u can go to psp-hacks.com and download one of the easy packages that comes with all files, installs them to your psp for you, and walks u thru it.
