I really like your female connectors... and you are indeed hooked up correctly.
Anyhow, same response? Crap, crap, crap. I am afraid that 16u2 is shot (Uno R3 USB2TTL comms). You will need to remove that 16u2 and replace it in order to recover the board. Sorry about that. The only other thing I can think of is a last ditch test of finding a MS Windoze machine and installing as normal (if it will try) and tapping the Pin5&6 for reset again to see if there is a response.
