Okay. So you had it connected, added the latest firmware and or made a few changes as you said. Hit Update and everything went fine?
Then the ESC was no longer responsive in the vehicle?
Completely dead? No signs of life? Cannot calibrate it?
And then just to further bookend this, it will also no longer talks to your computer?
Have you tried restarting your computer?
Reinstalling Castle Link?
Tried a different cable?
I couldn't get my Castle Link to work, it was in the package with a cable. I switched the cable and it worked. Now I have THAT cable in the package with the Castle Link
My final solution would be to recommend you contact Castle if you cannot get anywhere with it.
