i have tried everything to install cfw i also used rain mms maker
i hold L but the screen is black help
i have a NON fake memory stick (sandisk)-2gb
my psp is running on 4.05 ofw
and a another thing i am using vista does it make a difference
if your using the rain mms maker that i made a thread about,i explain the issues with vista and how to operate it right,chances are you just didnt fully read it.try rereading it again
kave-manual setup?you have to have an auto installer.manual adding wouldnt work cause the mms has to write a specific ipl code for your exact memorystick
