I have been using sentry mode for about 8 months with a 256 gb flash drive. I brought it inside and deleted the files in the 5hree folders under Teslacam keeping the three folders. When I take it to my model S, I have the gray dot and a red/ orange exclamation point. I’m stuck and don’t k ow how to get sentry mode or Dashcam up and running again.
