I understand.
In order to port Ubuntu Touch to your device, we need the android AOSP kernel with all specific modifications to talk to the various hardware components.
I don't know if there is a way to get those sources from elsewhere, but Cyanogen or Lineage guys achieve to get it, so there is a way...
Anyhow good luck. And maybe someone here can see your post and know a better answer.
