Help, Please

Hi, we're sorry to know about the situation. I would like to ask if you've managed to use the DJI Assistant 2? if yes, try to uninstall and re-install the DJI Assistant 2 and restart the aircraft again to see if there will be changes. However, if the message persists, please provide us with a screenshot for further check. In the mean-time, you may refer to our video tutorial for the firmware update. Kindly keep us posted on the latest progress. Thank you for your support.

Yes I used DJI Assistant 2, it all ways stop at 32% with a error code of 0X020C03, and it does reboot the AC.

Same problem when I try to down grade to V01.05.0300, stops at the same place at 32% and same error code 0X020C0P3
