Hello all and thanks for any help... I recently purchased a previously owned Phantom 2. I know it's outdated but I like it a lot and hope to learn the ropes with it and then move on to a bigger and better model. I'm finding out there is a lot to learn and I want to start by making sure it has all the firmware updates and is calibrated correctly. My questions are... What files should I download from the DJI site and what order should I run them. I have downloaded files from the DJI site and even though I connected the PC to the transmitter the on-screen sticks did not move in relation to movement of my controller sticks. It was like I had no connection, although the 'USB beep' happened when I plugged the controller in. In the meantime what does it mean when you get 3 beeps when you first turn the transmitter on? I think I read that 2 beeps means it's in GPS mode but I get 3 beeps. I want to make sure it's updated and airworthy. Right now I don't even know what mode I'm in. (Meaning GPS or ATTI or NAZA, not mode 1 or 2) Any help will be very much appreciated. The seller was not sure of the answers. I think someone else set it up for him and he just flew it. Outdated or not this thing is awesome! Thanks!!!
