Finally, I have decided it’s time to root my Samsung Galaxy S2 Android device.

Some of my reasons for rooting:

1. Installing custom ROMs / mods and kernels requires root access.
2. Performing a good backup of the device (apps & data, system & user) requires root access.
3. Getting rid of unwanted system apps requires root access.
4. My M.Sc. research will include writing a kernel module for the Android kernel, so better start getting comfortable with low-level now, right?

This post is a detailed (photo-documented) walkthrough of the rooting process. The rooting is done using Odin3 and CF-Root.
