Those are willing to help please read the following problems of mine:-
1) Im running FW3.52 and it works just fine
2) Then I upgraded it to FW3.52 - Update 4 and it works ok but cannot read the disc?
3) Tried to upgrade to FW3.71 (easy installer) and it doesnt do anything and my psp cannot read the disc too? The firmware maintains as FW3.52 - Update 4
Considering to help or thoughts on how to overcome this, you are certainly welcome...Thank you.
