Oddly enough, I do not think Sparkfun updated the 5v0 model. I appears to be an issue a month ago.Based on my observations, I do not believe that 2560 is bootloaded, so the FTDI will not work (No Blinky on D13). Do you have another Arduino? If so, hook up SPI style either by the ICSP headers or Pin headers (I know, you have neither nor).
Then, download the Atmega Board Programmer:
Gammon Forum : Electronics : Microprocessors : Atmega bootloader programmerAnd upload to your other Arduino. When you open the Serial Monitor, you should be able to zap it into shape
I can bootload through a USBtinyISP. Could I just use the normal Mega 2560 bootloader?
