Hi, I recently updated the X1 yoga 1st gen to the pushed out updates.
This laptop, other than the battery life decreasing (expected) has been doing fine.
However, after the recently pushed out updates, it stopped recognizing touch and stylus.
This maching was fine just prior to the BIOS flash and updates.
I tried to install the new 9/14 touchscreen drivers and it says "Target device not found" (even though it was working immediately prior to updates. (other topics similar to this are not pertinent to this situation)
My suspicion is that it is triggered by soft ware - BIOS, but I can't quite roll that back.
I would appreciate any help.

I have recently had the same problem and located the solution.
The Problem: Touch Firmware Update Tool for ThinkPad X1 Yoga fails and after device manager detects that compliant touch screen and pen are both disconnected.
Solution to fix this issue is to reset the system board, on the bottom of the machine there is a hole for rebooting, grab a thin paper clip and make sure the device is not connected to power. This will reset the laptop and when it comes back on, touch functionality is restored.

I am unsure but do you know how to report this to Lenovo?
it is not good that they are pushing out updates that are causing target components to fail
