Hi! I have problem updating the Z15 GH3. I have mounted and balanced a GH4.
Sometimes the assistant says: Bad Gateway
The IMU seems to update succesfull to version 1.12
The GCU seems to update succesfull to version 3.0
I get upgrade error trying to update CMU.
I get upgrade error trying to update HD-AV.

Assistant version 1.4
Recommended driver installed.
Tried on both win 7 and Win 8.

Here is a video of the chicken dance. Password: gimbal


Please advice. Kind Regards / Olof Segerberg

And its a Wookong system.

Did you get this problem solved?  If you are getting bad gateway error, check to ensure you have the newest available DJI Assistant application.   When that is done make sure your Wookong controller firmware is up to date.
