Google Nexus 7 was announced at the Google’s Annual Developers Conference I/O. Google Nexus 7 comes with a 7-inch display and Tegra 3 processor and runs on the newest version of Android Jelly Bean with an inexpensive price tag of $199. This new device from Google has it all and is available for pre order sales now, you can order through Google Play Store and it will be shipped in two to three weeks from now.
As you can see the device haven’t yet released and there’s already a method to root the device, quite amazing isn’t it? All thanks to the unlockable bootloader that made it easier for the developers to do so. The root method is quite easy and requires the use of ADB and fastboot via command line. It doesn’t need to be Windows or Mac or Linux as long as you have Android SDK installed on your computer.
While rooting your phone, the data will be flashed when you will unlock the bootloader so you probably might want to make a backup of your data and then proceed further. As the development on this particular device goes on at that pace then this surely can become a developer’s favorite. For a complete guide and download links head over to this thread.
