TheToolkit is a great tool for any Galaxy Nexus owner since it easily unlocks the bootloader, roots the phone, and installs ClockWord Mod Recovery to get you all ready and set up for your flashing needs. It’s pretty much a one stop shop for anyone looking to really customize their hardware.
Developed by senior moderator mskip it has gotten even better in version 4.0 there is a new option that will automatically install all required drivers. Also with version 4.0, you can now backup and restore apps and app data, and as a bonus for donators, there is a new “tips, tricks and tweaks” section available.
If you’re keen just visit the forum thread and follow the instructions there to get ready!
