The other day I turned on my drone and had the red banner to update to the new firmware. I downloaded it, hooked back up the the Phantom and proceeded to update, or so I thought. It finished and rebooted and I calibrated the IMU and controller and went and flew. No problems, still good range, control, etc. Well tonight I hooked up to it and guess what....red banner....firmware update needed. I hooked up to the drone and sure enough it says 1.6.8+ as the firmware. I will try again when I charge up a battery (I can't fly for a few days so I don't want to charge it tonight). Beats me what happened. Thanks for listening...
