Bricked Jaguar?

[JHebes]

So the other day, myself and fellow programmers were trying to upgrade the firmware on our jaguars (The black ones) through the 2CAN web interface. Something happened, and it appears we have flashed the firmware without actually putting a new one on. Now we cannot get a response (i.e. no lights, fan, nothing).
We tried constructing a serial port adapter and using BDC-COMM-101 to fix it, but even through the serial connection, BDC-COMM could not see it. We're just about out of ideas. Does anyone have any recommendations?
