I just did a v1.4.0010 firmware upgrade on the P3 aircraft which seemed to work (camera light turned solid green). But I can't get the RC to upgrade. I upgraded to the GO app. It told me I could not upgrade the firmware thru the app, so I put the .bin file (by itself) on the usb stick, turned on the RC and waited. Nothing appeared to be happening (no blue light) so I tried connecting the rc to the aircraft's memory card via usb. Still nothing. I tried putting it on a new usb stick. Same results.
I'm still getting a upgrade required with usb disk message. When I look at the txt report it says: firmware on the sd card is identical to or older that the current RC firmware. I'm using the same v1.4.0010 as I used for the aircraft.
Update: I reverted back to v1.3.2 for the RC which was accepted but it still didn't show the intelligent flight modes. So I deleted the GO app and reinstalled. It works! Now to actually fly it.
