Samsung Galaxy Nexus is a showcase device to demonstrate the capabilities of the new Android 4.0 Ice Cream Sandwich in all its stock glory without the added layers of GUI that we usually expect from other Android manufacturers on their phones, for instance HTC Sense and TouchWiz. It didn’t take much time for the first performance benchmarks of the device to appear online and its comparisons to the current crop if high-end devices namely Samsung Galaxy S2 (SII) and iPhone 4S. XDA forums member Chainfire has released the CF-Root method based on flashing the insecure kernel to root the Samsung Galaxy Nexus. This is currently the preferred method to root this device and it also installs a handful of other features such as CWM, Superuser, Busybox etc. on the device that can be helpful in the future to flash new kernels or custom Roms. Note that CF-Root kernel is taken from stock on Galaxy Nexus only with the following added:

- Superuser v3
- Busybox v1.19
- Custom boot / init scripts
- Insecure

So this root method is preferred if you want to keep you device as close as possible to the stock with only the added root feature.

Note: Rooting, Jailbreaking or customizing your device can be risky, and you may end-up bricking your device! Follow the instructions posted here at your own responsibility as Inspired Geek will not be responsible for any damage to your device.

Required Downloads

- Download the ODIN file and then extract the .zip file.

- Download the suitable insecure CF-Root kernel for your device from this list. Then extract the tar file from the zip file that you downloaded using a WinZip or WinRAR etc.

- Correct USB drivers must be installed, so that programs can communicate with the device. Reboot computer after driver installation if required.


Step 1: Make sure that your device is in USB debugging mode: Settings -> Applications -> Development -> USB debugging.
