I finally had the DJI GO 4 install with the tablet ? After that , all the update have succeeds.
Thank you for your help !
This still doesn't solve your original problem. If you still can't connect your drone to a Windows machine, then your original problem still exists. If "updating the drone" was your original objective, you should've said that in the first place. You would've been told to "do that through the iPad/Android app" weeks ago and saved a lot of people a lot of time.
