I found a very dumb way to get root on the box and believe is not the expected method. Worse case I ll wait for the official write-up to be release but if someone can DM me the official way , I d be very curious.
I need some hints for getting the latex portion of topology.
Finally rooted 
Shell : Foothold is pretty obvious it takes time to find the method. Try to understand what you can and can’t do, read articles and payloads, maybe this is not the action that you try to do that is illegal but its name 
.
Root : Really easy, watch what you can run you will find it fast !
If someone need an hint DM, good luck !
