X1 Yoga touch screen and pen input stopped working after BIOS and firmware update

Lenovo automatically installed a BIOS (1.39) and firmware update in November.  Lenovo Vantage says these updates were completed successfully. The touchscreen and pen stopped worked after that.  Windows doesn't recognize the pen or touch input anymore.  Firmware tool says "device not found".   Latest BIOS update (1.40) and Windows update in December didn't help.

Re: X1 Yoga touch screen and pen input stopped working after BIOS and firmware update

My X1 Yoga touch screen stopped working too after BIOS(V1.40), Touch firmware(V4.20) update. My Win 10 is still at ver 1803.
I downgraded BIOS. But that doesn't help. Can't find a way to downgrade touch firmware.
@Lenovo, any solution? Obviously, I am not the only victim. It is ridiculous that your recommended update will cause such trouble.
In other thread, someone mentioned to replace screen. Really? The new update caused hardware damage?
