Hello I just bought a new I1 and haven't even been able to fly it . As per instruction it says to up grade firmware 1st to make sure you have latest one . Yes this sound simple and easy . I'm sorta a computer nerd so doing this as they say was simple except after upgrading the AC and RC and battery . I read the text files and it seem one of them didn't upgrade. one text file read upgrading . The AC did do all the dances with the camera gimbel and showed a green light when it was done . The RC did upgrade and I confirmed it with the pilot app. So tried to play with it in the house ( not props ) just to see how the app worked . Nothing happen The RC could not detect the AC , Just the Ac status led stayed red and same for the LED on RC. App did not show the AC was even there . Tried to relink the controller with AC because some say after firmware up grade , you might have to do that . That didn't work either . So tried to redo firmware in AC again 1st attempt noting happen but the normal power up dance and then status led light just turned red . Sat there for over 1/2 before I powered it down tex file read fail to upgrade try again so I did with the same thing happening . Yes I did try reformatting card and re downloading file and also tried that with the card that came with unit and also another one and put the .bin file on card and also erased .tex files . So do I have do I have a 3K brick with a red light or what . any help would be welcomed
