I have read about every post I can find relating to this topic and nothing has resolved this issue. I use to be able to connect my phantom to my computer but I am no longer able here is what happens:

1) I connect my phantom to my computer & start up DJI Assistant 2
2) I turn on the drone
3) I hear the USB sound windows makes when a device is connected.
4) Immedietly after that, I hear the USB disconnect sound windows makes.
5) sometime DJI assistant 2 connects its shows connection but immidiately it goes away


also having vision sensor error after updating precise fly data base. not transferring  live image

Hi there, sorry to hear about the issue you encountered. Please change to another cable and try again to see if it can connect. If possible, please also try with another computer to see if it works. If succeed, please refresh the firmware to see if the image transmission issue can be solved.

Sorry to hear about this. If it is possible, please try with a different computer. If it still does not work, you may need to send the drone back for a check. If you are located in India, it is suggested that you contact the retailer for assistance, or you can contact our support via email at http://www.dji.com/support to start a case.

Hi Thanks for your reply..

After so many try I have managed to connect it.
1. I tried refresh the firmware but still after 64% aircraft restarted (Battery light was on, battery did not restart) so firmware does not refreshed.
2. tried visual calibration, at last its gives error of screen resolution. as I did on 27" monitor it might be due to that, will do on laptop today.

Main thing I notice while doing these try, Live Image transmission started twice and again went off..

so much confusion whether it has any software issue or hardware... dont know will try today again and  update here.
