Root T-Mobile Galaxy Note 4 SM-N910T using CF Auto Root

T-Mobile has always been the most friendly carrier when it comes to hackability of Android devices. While most carriers in the US sells devices with locked bootloader, T-Mobile sells its Android devices as bootloader unlocked making it easier for users to root their device. The T-Mobile Galaxy Note 4 too comes with an unlocked bootloader which you can easily root using CF Auto Root by Chainfire.

CF Auto Root is a rooting tool developed by the renowned developer Chainfire for rooting Samsung Galaxy devices. CF Auto Root uses Chainfire’s own SuperSU app to manage superuser permissions for apps and ADB.

T-Mobile Galaxy Note 4 runs on the APQ8084 chipset from Qualcomm which supports LTE bands, unlike the international Exynos 5 variant. Also, it’s often less painful for developers to root and make custom ROMs (specially AOSP based) on devices running Qualcomm chipsets since the company releases source code for its architecture. Samsung doesn’t releases source code for its Exynos chipsets and hence the incompatibility with AOSP based custom ROMs.

There are many benefits to rooting an Android device, you’d be able to completely remove bloatware from your Note 4 with root access, giving better performance and battery life on the device. Other than that, there are several apps on the Play store that takes advantage of root access on your phone and help turbo boost the productivity of your device.

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-N910T!

This guide is specifically for the T-Mobile Galaxy Note 4 with model no. SM-N910T. 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.

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-trltetmo-trltetmo-smn910t.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.

    1. Power off your phone first and wait for 6-7 seconds after display is off.

      └ 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-trltetmo-trltetmo-smn910t.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.

    Note 4 / SM-910T / T-Mobile/ 5.0.1

    Very easy process, Rooted in few minutes according to video. I installed Custom ROM RAPTURE 3.1 UVU1COD6 (Developer: iB4STiD)


  • CLR

    My phone loads into Odin as ID:COM 0:[COM5] instead of 0:[COM7] like it does for your phone in your video. The PDA autoload has failed more than once when I press start. Would you please provide insight as to what is the irregularity taking place?

  • Done in 2 minutes, first try. Great Explanation.

  • Danny Winters

    The instructions use odin3 v 3.07. When you download/unpack the link, it has Odin3 v3.10 VERY DIFFERENT!!! It is NOT obvious how the settings line up!!!

    So I found a copy of Odin3 v3.07 followed all the instructions…and now the phone will not finsh recovery.. and will not boot at all.
