Hi guys I need some help I have my psp hacked the thing is my dad hacked it and I don't know a thing and my dad does not remember much so I am kind of lost so please I need your help guys. so this is my problem my psp START and SELECT buttons don't work but I don't think is any physical problem because I opened my psp and I didn't find a problem so I think it may be my custom firmware that is causing this problem or maybe not so I want to know if that is the problem or what is causing my start and select buttons not to work I am on 5.50 prome-4 I think is a old CFW and how can I update to a latest one. I will really love if you guys could help I am really lost and I need help thanks guys
