My phantom is 3 weeks old and I have updated to the new firmware. I did go into the advanced settings and checked the IOC box to activate Home Lock, but it does not work in flight. While I have the Phantom connected to my PC, the HL-CL-Off switch gets the proper responses within the Assistant software. When I turn on(plug the battery in), my Phantom will blink 2 green once it is ready to fly- HL and GPS selected. However, the Phantom always responds to commands as if it is in Course Lock. The Come Home feature works, so it knows where I am...I did not test this feature before the firmware upgrade. Any suggestions?
