So I restored the sst to original and installed the kexts using Hackintool. CHID is loading but nothing works still.

looks like I have the same touch pad model. I calculated its GPIO pin and it is 264 dec = 0x108 hex. I tried to edit DSDT.aml but the touchpad doesn't work anyway. Maybe I have a lack of knowledge...

Stupid question but did you try the F6 button? (trackpad disable button)
