If you’re looking for tools to help you root the Samsung Galaxy Nexus, than the answer is Superboot v2, as one of the most effective ways to do so. It works on Windows, Mac and Linux and it’s the work of Paul O’Brein aka Modaco. This second version of the Superboot tool allows one to enter superuser mode and enjoy the full Android experience.
Windows users will only need to extract the Superboot ZIP file and make the Galaxy Nexus enter bootloader mode, connecting it to a PC via USB afterwards. Then you double click on the BAT file and the process will start. If you’re on OS X or Linux, things are more complicated and involve terminal commands, but you have instructions on the MoDaCo forums over here.
This root method requires handsets that have already been unlocked at bootloader level, so keep that in mind. The version of Galaxy Nexus that’s being toyed with this way is the international HSPA+ one, so what we’ve written here may not work on Verizon’s flavor of the smartphone, especially if it’s the LTE one. Warranty goes away after applying the root, know that!
