How to boot into linux vim2

just got my vim2 and wondering how to boot into linux build on the vim2 is Nougat 20170929 Kernel 3.14.29 Version 7.1.2.
A bit wary as don’t want to brick it just yet.


there are some instruction in this post/howto boot for example an linux distribution from microSD card.

I used these on VIM1 but should work on VIM2 with Android U-Boot.
