Ok, I think I'm doing this right. I put my 64 gb micro sd card back into the Phantom 3 Advanced. I had taken it out before sending my drone in for repair. Apparently all they did was add a new gimbal according to the accompanying invoice. So I plug my phone into the remote with a usb cord and turn on the drone. I never get a green light on the remote control and the dji go app gets stuck on the phantom 4 and won't let me change models. From here I can't change it but once I turn the drone off I can select which model I want to choose. Any ideas what I am doing wrong? It just came back from dji so I'm sure it is working properly.
