I am facing the issue described in this thread Looking for Thinkpad X1 Carbon 6th gen working Thunderbolt bin file
My machine is fine (excel thb port, HDMI and any option to get video out to my ext monitor not working) but out of warranty and too good to retire because of this bad thb3 rom issue that I read quite a lot have managed to fix with the reflash process
I am located in Denmark and am looking for a technician that knows how to flash/ fix the THB 3 rom on my Lenovo x1 carbon gen 6- please get in touch
