Hi guys New to this site so hope this is where I can ask some questions, I have had my Phantom 2 for two days now and thinking I might have a $1000 paper weight now. Problem I am having is - I have updated the firmware, calibrated IMU etc... done compass cal and everything else I could see to do. When I turn the phantom on and the tx as well I get a slow flashing yellow light which I understand indicated it is ok to fly with out GPS, when I go to turn the motors on with the transmitter by pulling diagonal downwards as instructions state, I get a quick red flash on the Phantom unit and it keeps flashing slow yellow. I am at my wits end and just can not for the life of me get the thing to start up. Am guessing it is software related somewhere along the line but no idea how to tackle it. Is it possible to roll back to factory settings and start fresh? Any thoughts would be highly appreciated as DJI seem to not be getting back to me Thanks!
