I have come across this problem myself, and *should* be reversible. The bad part is, if you do not already have a serial to CAN adapter handy, this will be the time to make one.

Included in the Driver Station software and Utility Updates, there is a program called BDC-Comm. Start that up with only one of the bricked Jaguars plugged into the CAN port (For serial communications, you must plug your serial adapter into the left port of the Jaguar. Remember to terminate the other port.) Once BDC-Comm has started, there should be a menu item somewhere along the lines of "Recover Firmware" (IIRC, it's in the File menu). Select your firmware bin and flash it using the recovery feature. This should bring your Jaguar back to its normal life.

The fast red strobe would indicate a CAN error. Make sure you have your termination resistor in place for the network to run correctly.
