Ubuntu touch on a T510

[popop51]

I am currently running with a 2015 MBP OS Catalina, i also have a 2019 Galaxy Tab A T510. I have Ubuntu 20.10 installed via Virtualbox on the Mac. THE Ultimate goal is to install Ubuntu touch on the Tab A. I have platform-tools loaded but dont know enough to use them. I also have ubports, halium boot and Samsung-USB tethering loaded on the Tab A SD card per some instructions I found. I am having to piece this all together which is fun but I seem to be going in circles lol!

Why doesn't Ubuntu see the Tab A?
How do I flash the Tab A?
Is there a step by step that goes ALL the way through the process for a noob like me. I have Zero Terminal experience and want to learn.

As anyone can see I’m in way over my head but willing to learn
