Also when I turned off my psp and turned it back on again, I was back to the 1.5 firmware. Everytime when I turn on my PSP, do I have to do the stuff with Devhook? And can someone please help me, because I cant run my Fifa soccer 06 iso after I do all the stuff with devhook to make it 2.5 firmware. So any help would be greatly appreciated. thanks
