KingRoot PC is a program that will let you root your Android device just by connecting it to your computer via USB. Although the program’s interface is in Chinese, you won’t have to learn the language in order to use it. The process to root your Android device with KingRootPC is very simple: enable ‘USB debug’ mode (find it under ‘developer options’), connect your device to a PC via USB and then push the big blue button within the program’s interface. 
So if you wish to try out the latest Android 5.1.1 Lollipop version on your Galaxy Mega 5.8, you will need to install an Android 5.1.1 Lollipop custom ROM on it.

Your device will be rooted in a matter of seconds. Please remember that KingRootPC might not be able to identify certain Android devices since it doesn’t support all models. Despite that fact, it’s a very useful (and user-friendly) program. KingRootPC is a decent program to root your device that works pretty well despite its flaws. By Laura Del Pino.
