I toggle S1 the required 5 times & rotate 360, lights turn green..every time, Then I toggle S1 once more & vertical rotate 360. No Green Lights, (Flashing yellow). It says ready to fly Non GPS mode on app.. I pushed it (my luck) & tried to take off & fly, it then turned green on the app (DJI vision) & had 6 -7 satellite's. It has a hard time calibrating vertical to acquire the green arm lights.. This is a newly acquired Phantom 2 V+ version 2.
