I would tell you from personal experience pertaining to your brothers psp problem, that 9 out of 10, the problem is a hardware problem and does not have a fix, unless the mobo gets replace by another one. This problem is normally cause by some form of a hard impact to the psp, like droping it to the floor, ect... The 1 percent would be a normal brick. In this case use a pandora battery and a magic memory stick to unbricked.
