Thinkpad X1 tablet gen3, USB-C not working after upgrade thunderbolt firmware

2020-07-10, 8:11 AM

This morning, i found my tablet's keyboard not connecting to Windows, it feels like the driver problem so i decide to upgrade it.


After i download and upgrade thunderbolt and firmware from (https://pcsupport.lenovo.com/us/en/products/tablets/thinkpad-tablet-series/thinkpad-x1-tablet-3rd-gen-20kj-20kk/downloads/ds504184)


i found USB-C not working anymore, no charging or data connect. Now it just shot down and cannot reboot again. :(


My tablet type is 20KJ, and it works fine before this upgrade.


Anyone can help me, thanks a lot!
