Hi.... I have the psp 3.01 firmware.Sorry but i am getting really crazy cause i still couldn't use this devhook.Everytime i try there is errors.Also there is no folders like the guides says. The folders are MP_ROOT/PICTURE/MUSIC/VIDEO/PSP..no folders like dh or like those told at the install guides. How can i install this devhook? Is there a version problem so the folders are different at my psp? Please help help help help help help.... Thanks for all..
