Check your cabling and termination resistors, if the cable loses connection at all during the bootloading process the Jaguar will remain in bootloader appearing "bricked". If you are not confidant in your cables several companies sell CAN cables already assembled. Also make sure your termination resistor is secure and properly connected. If you are using a 2CAN use the web dash features and the LED state to ensure you have good CAN connectivity.
