[USR-TC] Firmware Upgrade on Boot

Hello All, I accidentally bricked the NMC card in one of my TC1000s (firewall interrupted a firmware upgrade and now I just get a blinking RUN/FL light on boot.) Is there some way to force a firmware update through the console ports? I remember that I used to be able to do it with pcsdl.exe but I don't think that is compatible with the .dmf image files that the later model NMCs use.
