There is a known bug in the 2CAN firmware, which is supposedly fixed somewhere (I can't find the right one myself, maybe someone else can point us to it). When you recover the Jaguar using BDC-Comm, plug your serial cable into the left CAN port, and your resistor on the right. Make sure you do it one at a time - multiple Jaguars on the network stuck in the bootloader mode will give you that message. I happened to brick 2 of them myself trying to update through the 2CAN, and this worked immediately for me. If it still doesn't connect, make sure the serial cable and resistor are in place, and power cycle the Jaguar. It should connect, and you should be able to recover with the 101 firmware binary.
