Ok, I have been flying (and upgrading) for nearly a year now (P2 > P3P) without so much of an hiccup. However I have been unable to upgrade the phantom3P since 1.4 (which worked just fine). 1.5 & 1.6 are impossible. The P3 will start the initial start up and all sounds fine until after a minute or so the D,ddd just turns into a constant stream of noise. I have reformatted the sd card several times and that includes a 'deep' format. I am running on fully charges batteries and ensuring that the RC is switched off. The gimbal seems to be working fine but the there is no image to be seen in the app. I suspect that the onboard files have somehow become corrupt. There must be some sort of filing system actually in the P3 SD drive that needs to be over ridden. If anyone can help me solve this issue, I would be most grateful. Cheers!
