Does anyone know how to reset the controller (rc) so I can start the firmware update again? My drone firmware update was successful. Txt file, DD-D sound etc all good. The rc update is the problem. How can I reset the rc to start the firmware update again? I have the firmware bin file ready. Right now when I connect the sd card to the rc via the usb it does not start to update. It makes no sounds at all and the blue light stays on. When I first got the equipment I followed the update instructions that I got directly through app when connected to the rc. That update was not successful. I did not get all the detailed instructions until after that. So I have to restart the firmware update on the rc. The drone update is successful. Does anyone know the procedure to restart the rc firmware update?
