I had already written about the deploy.apk vnc viewer and busybox. this also works on some other androidboxes minix. by the new sourcelist, but you can also start many other os virtually with qemu and virt manger in linux on android. i also tried to install tv box on android, first i pulled an android marshmellow launcher in the store and besides atv also have a normal android on it. Actually, you should be able to continue with the Deploy.apk now. In addition, root should be possible from there. Caution Root is no longer a legal guarantee.
