I got the controller for my mavic 3 , i got my old controller unpaired and the RC pro paired and it flys great and everything but it has reset me back to how the mavic 3 was when it first was released and as we all can remember, that sucked , so im trying to upgrade the firmware and it just wont do it , i have now made it to 27% after 5 days , it just fails every time. I dont really know what to do , or why its doing this.
