I have been flying Phantoms for the past 6 months or so and never had this problem before. Yesterday I wasn't able to calibrate the GPS for some reason. I flipped the GPS Switch up and down 10 times like normal and the LED on the back of the Phantom would just blink a steady green constantly (about every half-second) without any change. I decided to fly it anyway out of GPS and it flew just fine. Today I tried installing the new firmware for the first time, and now the Phantom continues to blink the steady green but will not start up at all. It's as if the control will not connect to the Phantom. The NAZA Assist software will also not recognize the control and I have reinstalled the driver 3 times. Please help! Thanks!
