Lenovo Vantage updated the T480s BIOS on 8/9. I immediately started getting a Thunderbolt error when starting Windows 10 64, which says to update the Thunderbolt firmware. I downloaded the current firmware from Lenovo (n22th06w) but I get the following error when trying to update: 0x20D SDK_INVALID_OPERATION_IN_SAFE_MODE
What's the solution, Lenovo?

I tried resetting a few more times, no luck. For a while the controller disappeared until I reset it again with different BIOS settings for Thunderbolt BIOS assist mode. Once it's back, it's still stuck in safe mode.
