I was wondering, see if you short the 12V with 5V the FTDI will blew away, so you cannot talk to your chip!
I have fried my Sanguinlolu1.3a in the same way, but the story of shorting 5V and 12V is different
I replaced FTDI
It seems it doesn't work may be the atmega in the board fried too ???
I have a spare board so I replaced it !
