Hi, we're sorry for the troubles that it caused. Have you tried to uninstall and re-install the DJI assistant 2 then check if there will be changes? Have you tried to take a photo and check in if it will be recorded on your SD card? Please keep us posted on the latest progress.

You have tried powering everything down and restarting ?
Sometimes the update can 'stick' at 99%, and yet the upgrade has completed, it just isn't being reported correctly by the App'.

Perhaps a relink of aircraft to RC might help.

Hi and good day Tommy Silaban, my apologies for the unpleasant experienced. Please try a different cable or pc so that we can isolate the issue. What is the operating system of your computer? May I know what happened prior to the issue?
