The touchscreen does not work after install firmware

[Chuong2105]

Hi! First I'm sorry for my bad English. I have just bought my new laptop HP Spectre x360 15t ch000 and saw that when I used the pen (Active stylus), it's normal in the half of the bottom screen but in the half of the top screen it ran crazy. Then I tried to install the firmware SP79862 (Spectre 15 bl000). This was the big mistake when my touchscreen stopped working.There is a warning in ELAN EzTouchFilter, "No pen or touch input is available for this display",... I tried to rollback BIOS to Ver F.12, reset PC but I couldn't fix it. Someone help me please! 

Thank you!!!

Thank you for your respond! 

The product number of my laptop is: HP Spectre x360 Convertible Model 15t-ch000.

Last time it worked fine in 4/9/2018

I have installed Office 365, IDM, Winrar but I had reseted my laptop now. (When I installed HP UHD Touchscreen Controller Firmware Update sp79862 problem happened)

I tried what you instructed but

1/ In Device Manage, "HID-compliant touch screen"  didn't appear.

2/ Windows Update failed: Update for video playback on Windows 10 version 1709;  Known issues - Microsoft is not currently aware of any issues with this update;  Prerequisites - There are no prerequisites to apply this update.

3/ I ran UEFI to update bios to Ver F.12 but the tag Touchscreen (Component Test) still disappear.

I'm expecting your next instrucion.

Thank you!!!

I appreciate your time and efforts,

Let's check if the touchscreen works in BIOS, follow these steps:

1. Hold the power button for at least five seconds to turn off the computer.
2. Turn on the computer and immediately press the F10 key repeatedly, about once every second.
3. Check if the touchscreen works fine in BIOS.
