I can no longer control my phantom 3 with the remote control. However, I see the status of everything in the app and can let it rise to 1.2m via the app and let no further control via the RC.

In addition, I also have no image in the app of the camera. I can calibrate it etc. but nothing else. Have already watched a lot of YouTube videos and tried things but I do not see a solution anymore.
It almost seems like there just needs to be new firmware
He does not see the sd card, so update is not possible. Try multiple sd cards
Gimbal only gives a red light when it starts up, then it stays black.

Hello, I have the same problem, with the USB detection of the camera. I don't have video feedback and the update is impossible.  But as far as I'm concerned I can always take-off and control my drone but indeed, without the camera.
