@lakotaubp AWESOME 
and thank you so much for taking you time with me, very kind of you.
As fare, as I see it my tablet runs Android Version 9.0 aka so fare so good... I'm so very new in traffic here, and while Santa didn't have time to wipe it and put on Ubuntu Touch... I'll have to try it out on my own, with all the help I can get
You, the porter, need to build Halium (i.e. halium-boot.img and system.img) and install these together with the Ubuntu Touch rootfs in order to create a functioning Ubuntu Touch port.
Halium is built using source code for a modified version of the Android operating system called LineageOS. The required source code is available online and needs to be downloaded and configured to build the correct Halium version for each individual device port. The table below shows which versions are required for the different Halium versions.
Android version 7.1 - 9.0
Halium version 7.1 - 9.0
Lineage OS (LOS) 14.1 - 16.0
