Samsung Galaxy Nexus running Google’s latest Android 4.0 Ice Cream Sandwich operating system has already been rooted. News has come from a developer MoDaCo’s Paul O’Brien has announced a rooting solution for Samsung Galaxy Nexus smartphone. Solution includes a rooting software called Superboot which installs a specialized boot image to the Galaxy Nexus and automatically roots it at startup. Therefore, now you don’t have to play around with your partitions in order to get a full control over phone. Step by step procedure mentioned by the developer is given below: "The superboot image is also ‘insecure’, allowing you to use ‘adb remount’ as well as having full ADB root access to your device until such time as you reboot after running this process (it’s a non permanent ADB root as it’s a ‘fastboot boot’ and not a ‘fastboot flash’)"
Here’s how to do it: 1. Download Superboot r1 Zip file from here and extract to a directory. 2.Switch off your phone then turn on with the ‘volume up’ and ‘volume down’ buttons both pressed which will put your device in bootloader mode.Once you’re in bootloader mode, you’ll be greeted with a screen as shown below: 3.Now jump over to your system and RUN Command depending upon your operating system. Windows
On Windows, with your device plugged in to your PC, double click install-superboot-windows.bat file, that’s it.
On Mac, you will need to run terminal and execute the following from the directory location:
chmod +x install-superboot-mac.sh
On Linux, you will need to run terminal from the directory containing the files you unzipped, and punch in the following lines:
chmod +x install-superboot-linux.sh
Note: If you are using a retail Galaxy Nexus, you may need to unlock the bootloader first, using ‘./fastboot-windows oem unlock’ (or the appropriate version for your machine). Note that the OEM unlock sequence wipes your device
If you performed the above steps correctly, you will have complete root access to your Galaxy Nexus, and you’re ready to install apps or tweaks which are otherwise not allowed by Google to be executed on said device.
One thing that must be noted, this does require that your bootloader be unlocked. If you are using a retail version of the aforementioned device, the following command will unlock the device:
