There is a way to recover by using BDC-COMM in the command line.

Open up a command line terminal and navigate to the folder where you have bdc-comm.exe. To make it easy you can put it in your 'c' drive. I also recommend putting the firmware files in the same folder as bdc-comm.exe so that you do not have to type in a file path.

In the command line run the following:

1)
C:>bdc-comm.exe -c N

- replace the 'N' with the COM port number you are using

2)
# id X

- replace 'X' with the ID you had previously set for that Jaguar (factory default is 1)

3)
# update BlackJaguar-87.bin

- if the firmware is in the same folder as bdc-comm.exe, this will work. Be sure to change the file name for Gray Jaguar firmware.

The update should happen, showing progress as a percentage. Hopefully if everything went OK your Jaguar should be blinking again.

The files seem to be miss named, the BlackJaguar-87.bin file worked on a grey Jaguar, but the Jaguar-87.bin file caused it to crash.
Thank you for the help, I will try the position control again tomorrow.
