Just got my inspire and updated the firmware on the drone with no problem. However the controller won't update no matter what I do. I've followed the steps in DJI's guide repeatedly with no success. Tried to contact their live support but they ended the conversation with a screenshot of the guide after telling me to format the card which I did but couldn't tell them since they ended the conversation. Currently 40 minutes on hold in their customer service number. I've tried a Usb drive, a card reader and the gimbal to update the drone with no success. Anyone run into any issues with this?
