I bought a second inspire remote and the plan was to be able to use it with my Phantom 3 professional and as a second remote for the Inspire 1. I USB updated the new Inspire remote to v1.3.00, then I app-updated to 1.5.7. I never had any problem connecting to the Inspire, but when I tried pairing to the Phantom things got weird. The remote connected to the Phantom OK, but there was no live video feed, only black screen. I tried many things to try to fix this like resetting, re-installing dji go on IOS and Android devices and nothing worked on my v1.3.20+ firmware Phantom. In this process, I set the remote to slave setting. It disconnected. I rebooted the controller and it will not connect to dji go at all. On power up, the led turns red, beeps twice, then turns purple and does nothing. Now I think I may have bricked my controller. I was hoping there was a way to reset the controller to master without connecting to dji go. If not, I guess I'll be sending it back.
