webOS Dev Manager

webOS Dev Manager lets you install apps, transfer files and connect to a terminal of your TV in a nice graphical interface. It is available for Android, Windows, Linux and Mac.
This guide will show you how to install it on android/windows/mac/linux and how to connect it to your rooted TV.
This mini guide was written for rooted TVs, but webOS Dev Manager also supports LG developer mode if you cannot / don't want to root. LG Devmode is not covered in this guide (yet).
