Root Galaxy Note 4 SM-N910F using CF Auto Root

It has only been a few weeks since the release of Galaxy Note 4 and root for the device is already available. The Galaxy Note 4 SM-N910F is the LTE-A variant of the device based on qualcomm’s APQ8084 chipset. The device is bootloader unlocked by default and that’s why achieving root on the device didn’t took long for Chainfire.

Chainfire’s CF Auto Root works for most Samsung devices, and the Galaxy Note 4 root has also been achieved using the same root package. CF Auto Root uses Chainfire’s own SuperSU app to manage Superuser permissions.

If you’re new to rooting and stuff, then know that rooting your Galaxy Note 4 with CF Auto Root will void your device’s warranty and will also trip the Knox flag. If you don’t want the knox counter to represent that you’ve rooted your phone, then look for a pre-rooted firmware for your Galaxy Note 4. Most pre-rooted firmwares doesn’t trips Knox and keep its status at 0x0, which saves you from letting Samsung service center reps know that you’ve rooted or tinkered with the device’s system.

Enough talk? Okay, let’s get to the action and root Galaxy Note 4 SM-N910F.

Name CF Auto Root One Click Tool
Warranty Void Warranty.
Stability Stable Without Any Issues
Root Manager App SuperSU. It manages root permissions for apps on the device.

Warranty may be void of your device if you follow the procedures given on this page.

You only are responsible for your device. We won’t be liable if any damage occurs to your device and/or its components.


Before you begin with guide instructions below, make sure your android device is adequately charged — at least 50% battery of the device.


To make sure your device is eligible with this, you must first confirm its model no. in ‘About device’ option under Settings. Another way to confirm model no. is by looking for it on the packaging box of your device. It must be SM-N910F!

This guide is specifically for the Samsung Galaxy Note 4 with model no. SM-N910F. Do not use the procedures discussed here on any other device of Samsung or any other company. You have been warned!


Back up important data and stuff before you start playing around here as there are chances you might lose your apps and app-data (app settings, game progress, etc.), and in rare case, files on the internal memory, too.

For help on Backup and Restore, check out our exclusive page on that linked right below.



You must have proper and working driver installed on your windows computer to be able to successfully root your Galaxy Note 4. If you are not sure, check the link below.




Download the CF Auto Root file given below and transfer it to a separate folder on your computer (just to keep things tidy, that is).


DOWNLOAD LINK | File name: (25 MB)


Important Note: Backup important files stored on internal SD card of your device, so that in case a situation arises requiring you to do a factory reset after rooting, which might delete internal sd card too, your files will remain safe on PC.

  1. Extract/Unzip the CF-Auto-Root file, on your computer (using 7-zip free software, preferably)You’ll get the following files:
    • CF-Auto-Root-trlte-trltexx-smn910f.tar.md5
    • Odin3-v3.07.exe
    • Odin3.ini
    • tmax.dll
    • zlib.dll
  2. Disconnect the Galaxy Note 4 from PC if it is connected.
  3. Double-click the Odin3-v3.07.exe file to open Odin.
  4. Boot your Galaxy Note 4 into Download Mode:
    1. Power off your phone first and wait for 6-7 seconds after display is off.
    2. Press and hold these 3 buttons together until you see Warning! screen: Volume Down + Power + Home.
    3. Press Volume Up now to continue to Download Mode.
      └ For further help, check out our post on Galaxy Note 4 Download Mode →
  5. Connect Galaxy Note 4 to PC. Odin window will show an Added!! message in bottom left box. Odin’s screen would look like this:
    If you don’t get the Added! message, here are some troubleshooting tips:
    • Make sure you have installed driver for Galaxy Note 4 as said above.
    • If you have already installed driver, then uninstall them and reinstall back.
    • Connect using a different USB port on your PC.
    • Try a different USB cable. The original cable that came with your phone should work best, if not, try any other cable that’s new and of good quality.
    • Reboot phone and PC and then try again.
  6. Load the recovery file (extracted in Step 1) into Odin as instructed below:
    • Click on the PDA button on Odin and select the CF-Auto-Root-trlte-trltexx-smn910f.tar.md5 file (from step 1).
      Your Odin window should look like the screenshot below:
  7. Now in the Option section of Odin, make sure that Re-Partition box is unchecked. (Auto Reboot and F. Reset Time boxes remain checked, while all other boxes remain unchecked.)
  8. Double check the above two steps.
  9. Click the Start button to begin flashing CF-Auto-root on your Galaxy Note 4, and wait until you see a PASS! message in Odin’s top left box.
  10. When you get either RESET! or PASS! message, your phone will reboot into recovery and root your Galaxy Note 4 and again restart automatically. You can then disconnect your phone from PC.

If you see FAIL message instead of the RESET or PASS in Odin’s top left box, that’s a problem. Try this now: disconnect your Galaxy Note 4 from PC, close Odin, remove phone’s battery and put it back inside in 3-4 seconds, open Odin and then repeat from Step 3 of this guide again.

Also, If device is Stuck at setup connection or on any other process, then too, try this: disconnect your Galaxy Note 4 from PC, close Odin, remove phone’s battery and put it back inside in 3-4 seconds, open Odin and then repeat from Step 3 of this guide again.

NOTE: It may happen that your phone doesn’t automatically boot into recovery and root your phone. In that case follow the following above procedure except that in Step 7, Auto Reboot option is un-checked and then the instructions below:

  1. Pull out the battery and re-insert it.
  2. Boot your Galaxy Note 4 into Recovery Mode: Press and hold these 3 buttons together: Volume Up + Power + Home.
  3. Now, this will start the rooting process and will reboot the phone automatically when the process is done.

That’s all. If you need help regarding this, feel free to ask us in comments below.

Please advise

    • Stteve

      Hi where did you get origional FW from as i got exact same issue

      • Dawie Prinsloo

        Hey Stteve. At the time i downloaded the FW i was so anxious to install it and get my phone working again that i never really though of it to take note of the download site. You should find it rather quickly.. the FW you are looking for is the XXU1ANJ4. I just flashed this firmware using odin and everything was working fine again. Sure if you google for a download site you will find it without too much hassle. I will hower try to locate the download site and re-post to you.
        Hope you have success and good luck.

      • Dawie Prinsloo

        Hey Stteve.. if you are still looking to root your phone.. i have successfully done it myself. Go to: everything is there. Takes a few minutes and its done. Be sure to follow all the instructions and you will be allright. Goodluck

      • Dawie Prinsloo

        Use the CWM/TWRP method and youre sorted.
