Update Samsung Galaxy S2 GT-I9100 to Android Jelly Bean 4.3 using CyanogenMod 10.2 Custom ROM

The good thing I love about Samsung is, Samsung doesn’t forget its smartphones and tries to bring the latest operating system to its popular and best selling devices. But unfortunately we saw the updates for Samsung Galaxy S2 only till Android 4.1.2 Jelly Bean. Samsung has not decided/announced to roll out any new firmware update for Galaxy S2 until now.
