These are the guidelines to root the Samsung Galaxy Note 4 SM-N910H running the Android 5.1.1 Lollipop update. The guide teaches you how to root using Chainfire’s CF-Auto-Root tool and the Odin flashing tool — the same Odin that never saw an official release by Samsung developers but remains one of the best flashing tool for any device based on Android.

The CF-Auto-Root file in this guide is based on LMY47X.N910HXXU2COJ4 firmware and the Android 5.1.1 Lollipop software update. We do recommend you are running Android 5.1.1 Lollipop for this guide and find anew guide if the device is ever updated to Android 6.0 Marshmallow. However, that does not mean you need to be running the LMY47X.N910HXXU2COJ4 firmware — you do not. The firmware build ID is given by Chainfire purely to be used as an indicator and nothing more. Some Samsung devices will not boot the old images. The guide will work on many build numbers.

Rooting the Samsung Galaxy Note 4 SM-N910H on Android 5.1.1

  1. Enable the USB Debugging Mode on your Samsung Galaxy Note 4 before you connect it to the computer so it can be used with Odin.
  2. Drag the file from the default Downloads folder over to the desktop.
  3. Extract the rooting file to the desktop of the computer.
  4. Double-click on the Odin executable file and the flash tool will open. Leave it open.
  5. Do not make any changes to the default settings of the Odin app. (The default settings should read the F Reset Time and Auto Reboot options turned on and the Re-partition option left empty.)
  6. Boot the Samsung Galaxy Note 4 SM-N910H in download mode and connect it to the computer with the USB cable.
  7. Wait for the ID: COM port to light up the color green, signifying that your drivers are working and the device is connected successfully. (You can install the Universal ADB Driver on your computer and try again if you need to get the drivers working.)
  8. Click the AP button and browse the desktop for the rooting file.
  9. Click the Start button and wait for the flashing to complete. (You will get a pass message from the Odin application when the flashing is complete).
  10. Look at the display of your Samsung Galaxy Note 4 phablet and it will say it is restoring the stock recovery, cleaning up and rebooting in 10 seconds.

The Samsung Galaxy Note 4 SM-N910H will now reboot in recovery mode automatically. It must get in recovery for the guide to work. You can boot your device to recovery mode if it doesn’t happen automatically.

You can install the root checker application from the Google Play Store when you reboot the Galaxy Note 4 back in recovery mode. Wait for the root checker application to finish downloading and then open it up from your app drawer. Agree to any updates, including the SuperUser if it requests the update.

Anyone facing problems can try installing a different version of the Odin flashing tool and try the guide again. Sometimes it takes a few version before one works for you.
