    Hello Lawrence,

    Can you explain the exact steps taken and what is being observed?

    Are you able to communicate successfully before programming and after it becomes unresponsive? If this is the case it is likely the gauge may have had an issue during programming and become bricked. If the power is temporarily lost while programming this will happen.

    Are you able to recover the gauge?

    Sincerely,

    Hello Lawrence,

    If the gauge is programmed and after programming becomes unresponsive it is most likely bricked from bad programming. The only way to recover this is if the gauge is not sent to firmware mode after programming, you can attempt to program it again, if it is sent to firmware mode with bad programming it is not recoverable unless you can get it back into ROM mode.
