The Nexus S is now publicly available and what better way to celebrate Google’s own stance on “openness” than rooting the device. Usually a tedious process, rooting the Nexus S will not be the challenge you would expect, all thanks to Superboot.
Superboot is a boot.img that when flashed, will root your device the first time you boot (installing su and the superuser APK). No need to flash the system partition, no need to use ADB, no messing with the contents of your data partition, no overwriting the shipped ROM on your device, just flash the boot image using the instructions below and you’re done!
It’s really just that easy. Of course it comes with some risk (as do all software manipulating procedures) but this seems to be the best option that doesn’t put the user through an intensive rooting process.
Superboot is available for Windows, Mac and Linux, if you would like to download Superboot and root your device, follow the instructions at the original forum post, here.
