I haven't even got started before head banging with update obstacle. With brand new Phantom 4 I went through the instructions to get my gadget airborne and yet again the written instructions and reality collided. When I aquired my software for my iPhone and connected that with the controller unit (as instructed) the system huzzled for a while and declared that I must update its firmware a.s.a.p. That was exactly what I did and the next instruction was to connect the phone-cable to the drone itself. I did that too and another firmware update started. Along with that update message came also release notes, stating on page 2 that if you didn't powerdown/repower your control unit there MIGHT BE SOME TROUBLE connecting to it after firmware update on drone. Good advice, but somewhat late to be useful. The end result is that both controller and drone has been updated for firmware but they do not communicate with each other at all.
How can I re-install the firmware to both units? If I just ask for "check updates" both units declare to be running the latest firmware and do nothing. How can I re-establish the connection with my controller unit and drone?
Is there a method by which a "factory settings" including firmware can be set?
