"Unable to contact the Bootloader" When updating black jaguar

[lollypop2020]

Sorry about the delay, I put CAN on the back burner for a bit to get everything else done.

I'm fairly sure that our cable is correct and securely plugged in. We are not able to control voltage or anything like that, and Firmware/Hardware version say 0. It seemed like our black jaguar was communicating, but as I looked into it, I could get BDC-COMM to display the exact same things, (Connected, Trusted), even when the black jaguar wasn't plugged in. This makes me think that either our black jaguar is dead, or something is wrong with our cable. The blinking light on the jaguar DOES turn solid when we plug it in though, so I'm less inclined to think it's the cable. Also, if we unplug the black jaguar, it goes back to flashing yellow unless we've tried to update it or change the firmware. In that case, it appears to be "frozen" on solid yellow, even after all of the cables are unplugged. It remains this way until we turn it off and back on.
