There are plenty of reasons to root an Android device, from OS updates, de-skinning, getting rid of bloatware, customization, etc. But it can be a scary path to travel if you have no clue what you’re doing. We’ve gone through and outlined how to root your Samsung Galaxy Note II N7100 as well as install CyanogenMod 10.1 Nightly Builds.

Warning: Rooting voids the warranty of your device. We and the developers of these files are not responsible if anything happens to your device. Use this rooting guide at your own risk!

Pre-requisites:

  1. I recommend watching the video tutorial above while following this guide!
  2. You must do this tutorial on a Windows XP/Vista/7/8 PC.
  3. This WILL erase everything on your phone, so make a backup!
  4. The Galaxy Note II N7100 should be factory unlocked.
