iv just used pandoras battery to downgrade my friends 3.40 to 1.50.
this worked but now when i turn the psp on connected to the charger and without a battery in it, the screen doesnt work.
it will make the psp noise like it is tuning on, but the screen doesnt.
the screen flashes the XMB when i take the charger out.
whats happening here and how do i fix it?
