Hoping someone can help here. I have a Phantom 4 RTK and Phantom 4 RTK Remote Controller. Recently I tried updating the firmware to the latest version. Controller is now on 02.02.0612 and the drone was upgraded to the latest version but when I tested the drone and controller together the drone vilently vibrated on take off. I sent into a repair technician and they downgraded the firmware but this has failed as well. So I am stuck with a drone that will not upgrade or downgrade its firmware as it gets to 88% in the upgrade process and then fails. The drone will not connect to the controller either. I wish I hadnt upgraded the firmware now obviously but really stuck with what to do. Any help gratefully received.
