There are a few posts about touchscreens not working on the Spectre/Envy series after firmware updates without any resolution. I had this happen and I am happy to report that after giving up twice, I did manage to fix it.
Symptoms:
Following a firmware/bios update, no touchscreen response even within the HP UEFI testing suite. So we know it's not a driver issue or something within Windows.
Solution:
For my computer it was Softpaq 138532, which is a firmware update for Elan touchscreens. I had previously tried to install this update and it seemed to complete but with errors. This time, I instead extracted the .exe file (right click > extract to...) and then ran the executable UpdateMultiDevicesEDID.exe. This time, it went through a longer screen and then... I immediately have my touchscreen back! Pen input with pressure is also working
Hope this is useful to someone. I am not an HP employee.
