I am having the same issue as listed here https://h30434.www3.hp.com/t5/Notebook-Video-Display-and-Touch/HP-UHD-Touchscreen-Controller-Firmwar... and https://h30434.www3.hp.com/t5/Notebook-Video-Display-and-Touch/Touchscreen-Firmware-for-HP-Pavilion-... Basically i have run into the issue where the firmware that i flashed to my display is the wrong firmware (since for some reason the firmware update utility doesn't check for appropriate hardware) and as such have bricked the touch screen ability. Before you ask, as stated in the other forum posts, I have tried reinstalling software and drivers and have discovered that this isn't going to fix the firmware. I can re-install the operating system or try and use the HP driver assistant as many times as i want and it'll do nothing to restore the touchscreen firmware - the operating system and related drivers are on the SSD while the touchscreen firmware is written to the hardware's flash memory. I don't need drivers. I don't need an OS restore. I don't need a firmware update thats provided on the download page for the computer model. I need a download link for the original firmware that was installed when the computer shipped. I need the original touchscreen firmware. I've accidentally installed the incorrect firmware and want to overwrite this incorrect firmware with the correct firmware. I've tried the support assistant... and I've scoured the Internet looking for the firmware. This isn't a driver issue, and won't be repaired by updating / repairing or reinstalling the operating system: when I boot into the BIOS settings the screen digitizer registers touch incorrectly as well. The device was working fine before I installed a bunch of drivers and updates in an effort to fix a battery drain issue. This issue I managed to resolve, but in doing so I inadvertently seem to have installed the incorrect Touchscreen Controller Firmware. I am hoping that you can get in touch with someone who would have access to this particular model's original touch screen firmware and send me either a link to download or the original file. Thanks!

And, also you can reinstall windows operating system which will return your computer back to the original factory state. In that way, you can get the original touchscreen firmware.
The HP Cloud Recovery Tool allows you to download recovery software to a USB drive. You can use the downloaded recovery image file in order to install the Windows operating system.
