T470 Thunderbolt firmware update error

I have a T470S type 20HF running windows 10 (version 1703) that suddenly the Intel Thunderbolt Driver was updated and gives me the error "A Thunderbolt controller has experienced a problem and cannot connect to devices or other computers until new firmware is installed."

 

The computer is connected through a usb-c cable to a dockin station which has two monitors connected through display port cables.

 

I tried uninstalling the Intel Tunderbolt Software (ver. 17.4.78.500) and reinstalling it.

I tried installing thinkpad thunderbolt 3 dock and usc-c dock driver v10017.

I tried to install new firmware with the file N1WTH07W but it says "cannot find correct bin file"

 

I still get the same error and cannot use the monitors connected to the docking station.

 

Please help.

Re: T470 Thunderbolt firmware update error

I have exactly the same Problem, you've also noticed a shortened battery life? 

But I have the 20HG version of the T470s. Please correct model name in title to T470s.

Re: T470 Thunderbolt firmware update error

I had this same problem and used Gigabyte's Thunderbolt firmware installer to grab the .bin file from the Lenovo install.

 

https://www.gigabyte.com/Motherboard/GC-ALPINE-RIDGE-rev-10/support#support-dl-driver-thunderbolt

 

Take note of where Lenovo is unpackaging the files and use that location when asked to browse to the location of the .bin file.

 

Hope this helps.
