For the Jaguars that are dark (no LED activity), try the BDC-COMM "Recover Device" feature. Sometimes you might need to try it twice in a row to actually make contact with the boot-loader.

Make sure that you power cycle the Jaguar before attempting to recover to ensure the boot-loader is listening.

Did you power up and attempt to run these dark Jags all at the same time or individually?

For the Jaguars that went bad on the bot, describe what you were doing when they failed. Did they fail after updating the firmware? Did they fail when trying to run a motor? You said most of these worked with BDC-COMM individually; did you update the firmware and assign unique IDs individually, or was that attempted with multiple Jags on the bus? What is the LED doing; slow flash amber, fast flash amber, something else?

The more details the better; even if you think they might be insignificant.
