Are you & have you always had the "com" port error? Have you also uninstalled (probably from the sounds of it) uninstalled Odin (Patched version is required to go from US Firmware to Canadian firmware) - A different computer or laptop available? Makes no sense.... I've never had any problems switching from the US One UI beta back to Canada....So when I had some more time on my hands, I have tried everything else that I know.. I finally managed to get an error that says the serial (com) port not working. Any further ideas?? Thanks again!
I am using original Samsung cable, have tried every one of the 6 usb 2.0 ports on my desktop, deleted Samsung firmware and drivers. Reinstalled Samsung s9 drivers, still nothing..
