    My touchpad works like a charm with XOSI SSDT. It doesn't work with the other method, that I tried, so I go back to XOSI method. BTW. this method usually need few restart to start working.

    It's very easy. You need only rename _OSI to XOSI and then use this SSDT - https://github.com/kecinzer/hpelitebook850g5-opencore/blob/master/SSDT/SSDT-XOSI.dsl It simply emulates Windows 10.
