Welcome to the first in our new series on hacking your phone. We’re starting off by looking at how to customise the operating system on your phone. With Android, it’s possible to install custom ROMs and change almost any aspect of the phone’s software.
For this simple step-by-step guide, we’re going to be using a Samsung Galaxy SII (i9100 international edition) and showing you how to root it with Odin and then how to install CyanogenMod which is probably the most popular custom ROM for Android.
It has all the advantages of an unbloated stock Android Jelly Bean ROM with the bonus of some amazing extra features, massive potential for personalisation and an amazing launcher, lock screen and bundles widgets. Plus, it’s the easiest way to update the Galaxy S2 to Android 4.3 way before the networks are rolling out official upgrades.
Before we start though, a disclaimer: by rooting your phone or installing custom ROMs, you may be voiding your warranty. We take no responsibility if your phone is damaged or bricked by following these instructions.
