This is a question that has been asked many times over the years and has been requested but to this day it is still not part of the channel line up. I gave up a long time ago on ever getting US Cartoon Network on this venue. Baring another service, your best bet would be to install Mobdro on your Android box (assuming you have an Android box that allows you to install your own apps). Mobdro has US Cartoon Network and it works pretty well and is fairly dependable. It's the best way I've found to get Adult Swim.
