People tell you that downgrading firmware is dangerous and
troublesome? YES! Downgrading it YOURSELF is VERY dangerous and
will spoil your PSP if you do it wrong. Just ask the shop owner to
downgrade for you or get someone who is a professional in
downgrading it. Its just like driving a car. If you are trying to
learn how to drive a car by yourself without any instructor or
help, of cos its dangerous. But if you got a instructor, its would
be fine.
