Hi,
I just received my Phantom 4 this week and since the first boot, I've been having a load of error messages popping up in the DJI Go app.
I followed the steps it gave me to fix the issue by connecting the drone to DJI Assistant 2, and attempted to upgrade the phantom. The assistant application detected my drone and the upgrade process downloaded the update, but then it says "Upgrade Failed!".

Also the DJI Go app still shows me the same error message on and on and on...


Have a look at the images and let me know what am I doing wrong! This isnt my first drone, so I'm not a newbie, I've had the Phantom 3 pro before that and everything was great. Is it a problem with the drone itself??

Thanks!
George

Hi,
Please watch below tutorials first and upgrade your drone again.
Phantom 4 Tutorials-Firmware Upgrade:

Hi George! Did you try to update your Phantom 4 via DJI GO ?  Please do the vision sensors calibration in the DJI Assistant 2 to get rid of the notifications. Thank you!

It was a defect, DJI replaced my drone.

Thank you,
George

Im having problem too on my motors. It just wont ppwer up. All controls are working perfectly.

I recently updated the firmware. Thats the time the motors wont power up afterwards.

Please advise. Thanks.
