I have just tried again with the craft off and it's still not working for me
I can't even start the motors .
OK, the steps in order are:
Turn off Aircraft and remote controller
Format a Micro SD card using the default settings for FAT 32
Copy the WM610_FW_V01.08.01.00.bin file into the root directory of the Micro SD card
Insert the Micro SD card into the camera on your Inspire 1 and turn on the aircraft ONLY
Wait patiently until the aircraft switches from the dddd - dddd sound to the d dd sound indicating success
Turn off the aircraft
Turn on the Remote controller only.
Start the DJI GO App and on the first screen press and hold the Academy Icon in the top right corner
Once you see the downgrade screen, down grade to Version 1.58
Now restart both the remote and the app
In the status screen you should get a message telling you that there is a new version of firmware for the remote - V1.60
Upgrade the remote
Shut down the remote and app
Now Turn on the remote, followed by the aircraft followed by the app - you should have a green light on the remote and everything should work
If you do not have a green light ensure your remote is set to "Master" mode, then go through the linking procedure for the remote.
