Eminent Android developer and hacker Chainfire recently released his CF-Root tool for the Galaxy Nexus that roots the device on Android 4.0.2 Ice Cream Sandwich, and we’ve got the step-by-step guide ready after the jump!
News of the root tool comes straight from XDA Developers – a popular forum for Android enthusiasts, developers and hackers – in the form of an official thread from developer Chainfire in which he discusses his tool and how enthusiasts like you can use to root their device.
This rooted kernel is for the "rooting beginners" and those who want to keep as close to stock as possible. CF-Root takes the kernel from an original firmware, and just adds root and busybox.

Chainfire’s CF-Root tool does not come with a custom recovery like ClockworkMod Recovery, so you will have to flash it yourself. It’s a pretty simple procedure, and you can check it out in our post on how to flash ClockworkMod Recovery.
Step 1: Download the required kernel for your Galaxy Nexus:
You can check which version you should download by going to Settings > About phone and observing the build number.
Extract the .zip file.
Step 2: Ensure that your device is not connected to your computer.
Step 3: Download ODIN v1.85 [XDA Thread]. Launch it.
Step 4: Click on PDA and select CF-Root-xxx-vX.X.tar which you will find in the folder you extracted in Step 1.
Step 5: Switch off your Galaxy Nexus. Once it is completely shut down, press and hold Volume Down + Power buttons to boot into download mode.
Step 6: Once in download mode, connect your Galaxy Nexus with your computer.
Step 7: Ensure that you have not checked the Re-Partition option.
Step 8: Click on START and wait for your device to reboot.
If you followed the steps correctly, your Galaxy Nexus will now be rooted on Android 4.0.2 Ice Cream Sandwich with Chainfire’s CF-Root tool.
