Prior calibrations on Mini 2 performed succesfully and was able to fly. Now I am unable to fly no matter how many times I try to recalibrate. Once drone restarts (after "successful" calibration) from Flight Checklist status "Normal", it goes back to "Unable to fly" with all three error codes on screen (30055, 30056, 30084). Never crashed, only 10 flights in. I bought the drone in the USA and am currently in Europe for the summer and sending it back to DJI in the USA is not an option. Any of you encountered this and how did you resolve the issue? Thank you.

30055 = IMU not calibrated. Calibrate IMU.

A google for "dji error code 30056" seems to have found quite a few threads but I haven't looked at them to see if they are different threads.

Hi, oceanstef. Thank you for reaching out. The error codes indicate the following:
30056- Prompts that IMU calibration is incomplete. It is recommended to calibrate the IMU and restart the aircraft
30055/30084- Prompts that IMU calibration is required. It is recommended to calibrate the IMU Prompts that the IMU bias is too large.

You may try to calibrate the IMU by following the steps below:
Please go to Settings-Safety-IMU Calibration. Kindly restart the aircraft once calibration is successful. Please keep us posted. Thank you.

I went ahead and followed your steps. I got the "calibration successful" message. Once drone restarted, error messages appeared on the screen again - as if I didn't perform calibration at all.

Sounds good. Thank you.

Hi, oceanstef. Thank you for patiently waiting. We now received feedback from our relevant team. Please try to refresh the firmware of the aircraft using the DJI Assistant 2. Here is the download link: (https://www.dji.com/downloads/so ... sumer-drones-series). Remove the microSD card then try performing the IMU calibration again. Please keep us posted. Thank you.
