I've just returned a P4 Pro V2 to DJI for replacement under the Care Refresh Package due to a software fault.  The new P4 arrived today and having linked it to the controller I'm getting a constant IMU error messag.  I've gone throught the calibration process approx 5 times and restarted the UAV on each occasion but I still get the error message.  

I've been without this UAV for a few weeks now due to UPS inability to deliver to DJI promptly and I'm still no nearer getting back to commercial work with it.

Any help greatly appreciated.

Original case ref :CAS-9045419-V5H4X2

Hi there, we are sorry for the issue you encountered. Could you please tell us the exact error message? If possible, please provide us with a screenshot for further confirmation.

I get the IMU Error message so go through to the calibration page and the calibration process.  I get a message saying that the calibration has been successful but when I restart the UAV it still has an IMU Calibration Error
