Hello
Re: Hello
OK.
Make sure you have the correct version of STM DFU Driver
I made a video yesterday showing the installation processon on the TYT MD2017/Retevis RT-82 yesterday, which is basically the same, except for the buttons to get the radio to enter update mode
If you look at the video at around the 2 minute mark, it shows what you should see in the Windows device manager
