One click "mobile" Usually, this is done by downloading an apk and proceding on, but the range of devices it supports to achieve root is limited. I highly recommend Framaroot for this procedure.
Next, is the traditional method, the PC route . A bit more complicated but i found an app thats very simple intuitive app to use & function. It is, Kingo Root. Just download, and follow the prompts.
Dont forget rooting any android device comes with a possibilitie of "bricking" it. Read all instructional information throughly in any method i provide
Lastly, for the PC method you will need to enable "USB debugging" To enable you'll need to activate developer options. Go to settings> about device (or wherever you retrieve your phone's software/hardware info)> Build Number. Now click your build number 5-8 times to enable developer options. Go there in your settings, enable USB debugging, and tada!
