I am having a problem uploading the new bin via my laptop. I know to use the bin-80 first. I read about that. I am getting a "flash update fail". Here is how I have it connected: laptop doesn't have serial port, just a VGA connection so I took the null cable connected one end to the receiver and the other end to a usb to serial adapter and plugged that end to my laptop via USB. Is that the cause of my issue? Also, I reset my receiver to its factory settings before I started. I am using com1 port. I checked the bios and made sure the port was enabled and also checked the device manager. Any help would be appreciated.
