the safest way would be to use the network update feature in ur psp... (that is if u have wireless)


anyways here you go . just to tell u, once u get to OFW u will not be able to play any isos, and will not be able to run homebrew...

and please do stay active on the brew.

alright so i placed that file in the folder correctly with the folder having all upper case letters..the update starts but then comes back to the home menu and says "The game could not be started. (DADADADA)
