It's not possible to update everything with just a computer. You'll need to use the DJI GO app too. While it's easiest to follow these instructions, you could upgrade the aircraft firmware using the DJI Assistant 2 application like this and then upgrade the remote controller firmware from DJI GO (per these instructions).All the instructions for updating that I could find say nothing about using an iMac computer. Just mobile devices.
Yes.but the controller should be done via Mobile device, as how you have described in your attachment?
It's probably the cable. Use the micro USB cable that came with your Phantom or try a different micro USB cable if that's the cable you're using right now.Trying to update Firmware and get a message "Accessory Not Supported by this device"
Is that talking about the cord, or the P4 and RC, or ?
Probably not, but I like to restart everything once more before flying. That final restart happens naturally though since I do my firmware updates at home (instead of out in the field when I want to fly).The only different thing is that following the message "Update Complete" the AC shut down by it self and restarted so i don't know if the user have to restart the AC again.
