Hey im new to phantom 3 pro was given one in great shape from a friend who doesnt use it and was sick of firmware updates. I had to update the firmware went well with the coptor no problems but when trying to update the controller ut didnt take the update . Trued sd card tried from the coptor with usb cable . Also brought it to a supposed dji certified repair shop in town they couldnt get it to take either . Im wondering if i buy another controller would that be my easiest way out and will need anything else to link the new xontroller with my coptor. Thanks for any help at wits end .
