Rooted! 
What a journey!!! My first Insane rooted box!
So frustrating initially, I left and came back after a while many times, I’ve been through the java part (thanks to @HomeSen for helping to configure the initial m****n project) and got user after a long journey of trial and errors…
The root part has been “blindly” difficult, initially! So thanks to @bobd91 and @blaudoom, your nudges got me on the right path. Persistence did the rest
