Setting up p3s and cant get passed updates required in the go app. My home computer died so doing it thru my droid cell. I got a friend(actually a friend of a friend of a friend and took a week) to update my sd card with the latest firmware. It does not recognize the update. Still wants me to connect to device which I have no cable to go from cell(usb3.0 I think) to dji usb end. Can I get around this or do I have to order a cable and wait another week. Not going to by new computer to get this done and it looks like it will stop you from flying without getting regular updates. My Dad, 1/2 owner says put the ...... ...... on ebay!
