First time I opened my PSP, I saw four little rectangles.
They look like a connection which can be used for data
access to the PSP controller chip's.
Since I saw the video from the installation of "PSP on TV" at
I'm very sure about my supposition that something can be
controlled trough it, and it might be very important for
unbricking PSP's (in combination with the leaked "Sony unbricking files"
and the "JigKick battery")
If there is any additional information about this connection,
please post it in this thread.
