been going thru this nightmare of updating firmware p3p and I finally found this thread know about Ive downgraded my controller firmware, tried to install an older firmware for p3p reconnect controller to p3p and still was getting no signal and not much else. So i read this three go to look for wifi of my p3p don't see it but my bird annoyced home point has been marked check .....etc screen tells me I need updates #Screen shot 1 but let me take off then screen went blank but still had control of my p3p even camera i kept it low enuf to not fly off restarted the app on my android and it was back to operating like it had been before the update! All day I've been working on this and see above about a wifi thingy I still haven't found BUT down grading firmware got me back in the air ...the last update id done it started floating when I was use to it staying where i put it.... i swore off updates as i read that was a problem battery got low i brought it down and started to type this .
