Rooting is not limited to only tech-savvy guys any more. Any one with little or no knowledge can do this with number of easy-to-use tools available on the net. Unlock root is one such free software which can root almost any android phone available in the market. All you will require is a data cable for your phone, device drivers and a Windows PC.

Watch this video to see the exact process.
Rooting voids your phone’s warranty and you may brick your phone (chances are pretty less). Though you can unroot your phone any time and get back the warranty. I have tried this on two of my phones and it worked smoothly. At any point of time if you feel like unrooting the phone you can simply do it by following the same process. Just press the “Unroot” button this time.
