Bricked Board - HELP!

I managed to bring my Beagleboard to a complete halt. For no good
reason, that I can recall, I reset the board at the prompt immediately
after erasing NAND as shown below. I've attempted to reboot from the
SD and USB per "". Only the LED
closest to the audio input comes on. I am holding down the user
button prior to connecting the the USB cable to the PC. Any
suggestions? Thanks.
