Keep in mind I am Newbie. At the advice of a friend who is a professional photographer covering emergency situations and an expert P2V+ pilot I upgraded my P2V to the new software. I still cannot get video or telemetry to my Samsung Galaxy SII, even though I have solid wifi to the phantom I still get "Phantom Connection Broken" message on phone. Second, after the upgrade my camera rotates facing down upon power up and my controller lever no longer operates the camera angle. I'd lke to roll back to previous software and see if that solves my camera issue - then I will work on connecting to phone. Any ideas? Can someone walk me through rolling back software. Thanks for everything so far!
