Chosen Solution
I upgraded my firmware some time ago and lost camera transmission! I have tried everything to upgrade to latest firmware without success. I have purchased new cards and tried downloading via different computers. When I start the upgrade the dronr reads the card( red and green led flashes) for 2/3 minutes then freezes on red light. So frustrating as not had any other problem..drone still flys but have no vision. Takes photos ok.
