i don't use the usb, i just connect to power from my power supply do i need com3 or can it be flashed by com1 or com2? because i tryed com1 and com2 didnt work so i thought it was com3
what hardware do you have (CK3 with probe, Maximus extractor, home-made probe)? Is your drive a 7,8, or 9 series? I'm assuming that you have a 7 series since you're asking about com ports, but I'm not sure.
i tried to connect the usb to my ck3 and com it didn't detect com3 port, when i check in device manager ive got a exclamation on xuecuter ck3 pro-usb do i need to install usb drivers?
