Firmware Load Problem?

[BenzilLobo]

I have tried to update firmware from two different Win10 laptops. I had to load the USB driver with the first laptop but it was recognized on the 2nd laptop as the CH340 chip. Has anyone been able to update their A30 with the Smartto version 2.0 tool? The board is listed as version 3.1 on the control panel. I am able to move the 3 axis using Cura but cannot update firmware from it because there doesn't appear to be a hex file for it. As it stands i cannot update my printer to do auto-bed leveling and it sometimes resets due to the USB software issue. Is it possible I have a bad mainboard in my printer? Is there anything else i can try?

Thank you.
