Hello,
I bought yesterday a Mavic2 pro and after a normal flight outside yesterday evening I tryed to update to latest firmware 1.00.501, the RC was updated perfectly, but the AC gave problems.
Firstly I tried with DJI go 4, and it returned update failed.
I tried then with DJI Assistant 2 for Mavic, and after some try where the app returned error 0x02 at 84% of the process, it stopped freezed at 95% and I had to turn drone and the application off after 20 mins of nothing.
Result now if I connect the drone to the mac osx it doesn't want to connect.
I tried to repeat the procedure with DJI go 4 with android and also an iphone, the app returns alway update failure. I tried also with windows 10, and the device when I connect to the usb port show "unknow device" and it starts to connect and disconnect continuosly.
I tried different usb cables.
In the DJI go 4, the drone is connected but in version firmware it reports "version unknown", and no image transmission signal. I can't even see from the camera of the drone.
Please help
