well before i get stuck on imu calibration and i decide to refresh the firmware. but after i refresh the firmware using dji Assist i got stuck again.

did you know what is the error code means?

0x028103

Looks weird, it states 100%, however, failed. Try to reinstall the DJI Assistant 2 and restart the drone, then try it again? Did anything happen before you get stuck on IMU calibration?

Yes, it happen before 77% when drone restarting, after that error comes up

Hi there, I do apologize for the inconvenience caused. I just want to clarify, have you tried to uninstall and reinstall DJI Assistant 2?

Mission control, we have a problem. I wait till  the problems get worked out, then I do the updates. First people to update, gets the headaches.

Hi M Aadil, I am sorry for the trouble that your DJI Phantom 4 has caused you. With regard to the firmware refresh stuck on 99%, the driver of on your computer is it up to date. The DJI Assistant 2 may not recognize the drone properly if the driver is not up to date. I have posted an image where you can check for the driver on your computer. If you are using Mac you will need to reinstall the DJI Assistant 2. Please keep us posted. Thank you.
