Hi all, I am new to this forum and hope that I can get some help. I just got my unit and am in the set-up process. The first time things fired up great except for the camera. When I called the dealer they told me that I need to update the firmware. So I followed the video which showed that they wanted you to format the chip on your Iphone. I did the format on my PC. When I went to upload the firmware, the Root file was missing. Now the quad will not fire up. I have tried two different fully charged batteries with the same result. Any suggestions. :?:
