This is a step-by-step guide to root Sprint Google Galaxy Nexus devices running on the Android 4.0.4 Ice Cream Sandwich update. The guide uses the CF-Auto-Root tool by Chainfire and a unique exploit file that’s made for your Galaxy Nexus only. Once installed properly, you will have the SuperSU installed and enabled on your Galaxy Nexus so you can start doing things like using the Titanium backup app.
- The rooting exploit found in this guide is based on Android 4.0.4 Ice Cream Sandwich and IMM76D.L700FD02 firmware.
- You must follow this guide on the Google Galaxy Nexus by Sprint only and failing to do that will probbaly brick your device. You can check out your model number by tapping on the Menu > Settings > About Device > Model Number.
BEFORE WE BEGIN
- Download the Samsung USB Drivers  from our page and install them on your Windows computer before you start the guide. You cannot be sure the Odin flashing tool will detect your device without the drivers running. Those who have had the drivers running recently might be able to get away with not installing them again. However, the first sign of something not working should lead you to believe it’s a driver problem.
