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!

- You must do this tutorial on a Windows XP/Vista/7/8 PC.
- This WILL erase everything on your phone, so make a backup!
- The Galaxy Note II N7100 should be factory unlocked.
- Ensure the battery of the phone is charged more than 50%.
- This CF-Auto-Root file only works on the Samsung Galaxy Note II N7100. Applying this file to any other version of the Note II can “brick” your device.

Rooting the Galaxy Note II:
- Enable Developer Mode on the Note II by going to Settings – About Device – Developer Options.
- Enable Unknown Sources under Settings – Security.
- Plug the Note II into your computer and make sure all drivers are installed correctly. If you run into problems, try a different USB cable or port. Then turn your device off.
- Place the Note II into Download Mode by holding in the Power, Home, and Volume Down buttons at the same time. Then push the Volume Up button once this screen pops up.
- Unzip and open the CF-Auto-Root folder and right click on Odin.exe, then click on “Run as Administrator”.
- Make sure there is a yellow box in the screen, if not then the USB drivers did not install correctly and you should try a different USB cable/port.
- Once you have the yellow box, click on PDA and then browse for the file that was downloaded with Odin, (CF-Auto-Root-jflte-jfltexx-gti9505.tar.md5). Then click Start.
- Once that finishes and you get a green “PASS!” on the screen, your phone should re-boot to your normal home screen. Go into your applications and check to see if there is an app called “SuperSU” installed. If there is, then congrats! You’ve officially rooted your Note II. If not, then go back through these steps and make sure your follow everything correctly.
- Put your device back into “Download Mode” (up above, Step 4).
- Make sure your phone is plugged in through USB.
- Go back to the Odin window, make sure the yellow box shows up, and click on PDA again.
- Browse for the custom TWRP file (openrecovery-twrp-220.127.116.11-t03g.img.tar) and click “Start”.
- If you get a green “PASS!” then you’ve successfully installed TWRP on your Note II! If not then make sure your device is connected properly to the computer via USB.
- Verify your device is recognized under “My Computer” and double click on it.
- Make a folder called “ROMS” where all the other folders are.
- Drag and drop the CyanogenMod 10.1 .zip file AND the Gapps .zip file you downloaded earlier into the ROMS folder you just created. Then disconnect your device.
Installing CyanogenMod 10.1 & Gapps
- Turn off your Note II and boot into TWRP.
- Hold in the Power, Volume Up, and Home buttons until “Recovery Booting” appears in the top left corner. Then release the power button while holding down the Volume Up and the Home button until “TeamWin” appears on the screen.
- If you boot into regular recovery mode, then you did not install TWRP correctly. If you see a group of 8 buttons, then you’re in TWRP.
- Click on Wipe – Advanced Wipe and select “Dalvik Cache”, “Cache”, and “System”. Then move the slider to complete the wipe.
- Go back and click on Install and scroll down to the ROMS folder you created earlier. Click on the CyanogenMod .zip file and then slide to install the ROM. Once that finishes, click on the Gapps .zip file and install that as well. Otherwise you wont have Google Play Store.
- Once completed, click on “Home” again then click “Wipe”. This time just move the slider over to do a factory reset, this ensures everything is brand new for the ROM you just installed. After that finishes, just reboot your device and you should be on CyanogenMod 10.1!
