Thank you very much for the update, could you please try to following steps?
1. Check whether your calibration is correct again. You can check the following video.
2. Ensure that the aircraft is placed on a horizontal plane during calibration.
3. If the machine is on standby for a long period of time, power it off and allow it to cool to room temperature. Then, power it on for calibration.
4. Ensure that the firmware has been updated successfully.
5. If an error code appears, please tell us the Error Codes.
If your operation is correct but the calibration fails several times, please send your product back via this link: https://www.dji.com/support/repair
