I just tried Amlogic Burning Tool for the first time.
That meant firing up my old MacMini running Bootcamp Windows 7.
I recently ran the tool in a VMWare Windows VM (from Microsoft Edge Developer website - Microsoft Edge Development) on a Mac.
I chose the image and it errors 7% into the flash with errors.
Try a few times, that happened with me as well. Eventually it was able to flash the firmware. FWIW, this was with a Nexbox A95X (S905).
