gs2 homeYesterday, we’ve showed you how to manually install on Samsung Galaxy S2 the official Android 4.1.2 Jelly Bean XXLSR firmware. Today, we will guide you through rooting the software so you’ll have root access to your device. This is only for people who wish to explore more deeply into their phone and willing to take the risk involved in the process.

The rooting process will involve the use of a flashing tool known as Odin. A rooting kernel will flashed into your phone. It was developed by an XDA developer who also provided us with this step-by-step guide.

Remember that rooting your device will void your warranty. You can claim it back by “unrooting” your device. Flash the rooting kernel to your phone at your own risk.
