I think im in the same boat as you. my controller is on 4.0, but something went wrong when the copter was updating and then I got the version mismatched. my led lights are the same as yours, and I cant connect to the copter
Well, there's the old saying, "If it works, don't fix it" DJI is also having problems with "updates" and some bricking of drones in the process. I personally will not update anything of mine, that is working as it was intended.
