Now after I tried many times to upgrade the firmware and to click default, it says at the bottom left (Not DJI Intelligent Battery!) In the Live Data there is no power for the Pan, Tilt nor the roll. Maybe this is the problem since I have upgraded the firmware. Has anyone experienced this?

Make sure the battery is tightly inserted on your ronin
Make sure the firmware are up to date GCU1.0, IMU3.0

Has anyone experienced this?   lots of people
I guess dji thinks that people don't know how to put a battery in,since that's there solution
