Google confirmed three days ago that the official name of the latest Android OS will be Android 6.0 Marshmallow. Aside from revealing the new name, the Mountain View tech giant also released the Android 6.0 Developer Preview 3. Users who have updated the Nexus 9 with the aforementioned factory image can now gain root access by following the guide after the drop.

REQUIREMENTS

• The guide is only made for the Google Nexus 9. Don’t use this guide for any of the other Nexus devices.
• Verify your device runs the build number MPA44G Marshmallow from the About Device menu. The guide isn’t for the official Android 6.0 that’s coming out soon.

BEFORE WE BEGIN

• Download the Google USB Drivers You can download them from the same link during the guide that points to the ADB drivers. If you don’t have success with the guide, try rebooting the Windows PC and the new drivers should be working.
• Note that by following the guide below you are revoking the warranty. You’ll need to unroot the device by flashing a stock version of Android again to get the warranty working.
• Point to the Settings > About Device > tap over the build number until the display counts you down with the remaining amount of taps required to unlock the Developer Options menu. Once you unlock the menu, read the next step.
• Go back to the home screen and out of the About Device menu. Now enter the Settings and tap to enter the new Developer Options. Enable the USB Debugging Mode inside.
• You should be an advanced Android user to follow the guide.
