After trying to reset to factory mode from the menu, now my mini shows c106 when off or 0 when on. I tried to recover from PC via null modem but no help. My null modem is using pins 2,3 & 5. Apparently is communicating fine. However, at the middle of the transfer I get a some error. I have the feeling I have to use more pins on my cable or that is just time to buy a new one.
