Yes that's what I did. Pushed the reset on the range extender. Now Phantom comes up in the WiFi list on the iPhone, seems to connect fine, DJI app opens,  green light at the top of first page of DJI VIsion app, but when I try to open camera ..."Lost connection with Phantom". When I go to binding screen, won't scan my original package QR code. Dead in the water

You can add the last 6 numbers of the QR code on the bottom of your Phantom when you rebind manually.  Then tap the blue arrow at the top right.
