How to Root T-Mobile Galaxy Note 3 SM-N900T Without Tripping KNOX Warranty Counter

This is the root method that has worked perfectly on T-Mobile Galaxy Note 3 SM-N900T. One best feature of this root process is that it doesn’t trip the KNOX secure boot binary counter and easing the pain of worrying  about the KNOX warranty void 0x1 red flag. Unfortunately, once you trip the KNOX flag you can’t reset it back to normal again. So the concrete solution on how to root with T-Mobile Galaxy Note 3 is by using the Root_de_la_vega, which is designed to bypass and will do no harm the KNOX security suite.

The Root de la vega has been developed and brought to us  by @designgears (the creator of Root_de_la_Vega) and @Chainfire (the man who brings us the SuperSU and CF-Auto-Root for a very long time now).  As many of us from Android community, including Android developers, advanced users and tinkerers have been aware of the latest Samsung KNOX security apps for it limits us into further personal customization.

The vital component of Root de la Vega on Galaxy Note 3 equipped with KNOX
If you wonder how KNOX actually works, here’s a brief explanation so there wouldn’t too much confusion why we highly recommend this as the best approach to root the T-Mobile  Galaxy Note 3 SM-N900T. The KNOX  apps is a security platform designed by Samsung engineers and can be found on some newer Samsung smartphones and tablets. This is all explained in the KNOX white paper available on the Samsung website but this one is just a small detail about why if we root it triggers this KNOX platform.

KNOX has its own  isolated and secure environment within the mobile device,  so-called container. One of these containers also  includes  a secured bootloader. The bootloader is the place in the Android system (Qualcomm SecureBoot)  where tinkerers should avoid from messing it up. Once the bootloader detects any unsigned ROMs, kernels, modem, including root kernels it trips the KNOX WARRANTY VOID flag is set to 0x1. In short, it will switched the device into CUSTOM when you try to put something else in there that it doesn’t approve by the KNOX security system. KNOX has its own isolated memory causing red-flag once it gets re-written by any unsecure boot (kernel), recovery and other system images that are not officially designed by Samsung.

Samsung Galaxy Note 3 KNOX Warranty Void 0×1.
This is an example of Samsung Galaxy Note 3 System Status switched to Custom and shows the KNOX Warranty Void: 0×1.

This security platform can be actually seen when you reboot your Galaxy Note 3 into Odin download  mode screen, and it   tells you that device is switched to CUSTOM from Official status. When this binary counter has being tripped-off it will automatically void the smartphone’s warranty and causing the KNOX warranty void 0x1 red-flag. The problem is, it is not reversible by any means by now,  you can’t turn it back to normal status again. So the only solution by this scenario in order for you to root your T-Mo Galaxy Note 3 without harming that KNOX thing, you should only use this Root de la Vega, that is basically compatible and friendly with KNOX suite and most importantly it will not trip the binary counter.

Root Galaxy Note 3 N900T on 4.4.2 Update Without Tripping KNOX Warranty Counter

This method is for those who already have the latest 4.4.2 updates but did not use any other root method and still keeps the KNOX warranty counter on “0x0”. This root method is a simpler approach without knocking KNOX using Geohot’s “TowelRoot”. Now on 4.4.2 updates we cannot directly use “Towelroot” as it was only worked perfectly on 4.4.2 updates not later than June 3rd 2014. To make sure just check your 4.4.2 firmware build numbers by navigating through Settings>>About device>>Software info.

Towelroot can directly root on the following T-Mobile Galaxy Note 3 4.4.2 software updates:
N900TUVUCNB4 (February 2014 build)
N900TUVUDNE6 (May 2014 build)

Just download and install towelroot on your Galaxy Note 3 
Use your device stock browser and navigate to towelroot. Just click the main center logo to download the app.

Once you have downloaded the towelroot app, locate it in your files then run it and click “Make it Rain” .  Wait a few seconds and then reboot your phone.

Right after it reboots open up the SuperSU app, if it’ll ask you to update the binary or you’ll see an error message that says something like ” SuperSU has stopped” just grab the latest SuperSU from play store.


Note 3 SUperSU

Now, on any newer 4.4.2 updates using ‘Towelroot’ is still a convenient root method but we need a few extra workaround to achieve root.  As mentioned above that towelroot will only perfectly worked on older 4.4.2 updates so all we need is an older 4.4.2 “kernel version”  such as the ‘NE6 kernel’ as the root image only penetrates the kernel side and not on the entire Android system images.

This root has  worked on  any newer 4.4.2 updates but we need to revert back the phone to an older kernel version such as the following:  
N900TUVUDNF9 (August 22nd 2014 build)
N900TUVUDNF4 (July 19th 2014 build)
N900TUVUDNF1 (June 17th 2014 build)

First grab the towelroot but don’t run it yet as we are going to install back the older kernel version and the newer kernel.

N900TUVUDNE6 4.4.2 Kernel (link)

Download the default stock kernel version that corresponds to your phone’s current firmware build number so the root should stick.

This list will be updated if and when there is a new stock kernel available.

All Kernel builds has been extracted from the full stock firmware by XDA-developer’s senior member “toastido” at

Step 1: Reverting back to  N900TUVUDNE6 Kernel

Power off the phone, then press and hold down the Volume Down, Home and Power button at the same time. Then let go of the power button when you see the message that ask you to press Volume Up to continue.

Connect your Galaxy Note 3 to the computer via USB cable. See Odin’s ID:COM bar, it should turn to blue color and shows you the USB port number of your Galaxy Note 3 connection with the computer. There is also a word that says “Added” in the log-cat box. If you ain’t see any response, try to recheck the USB cable and re-install the USB Driver.

Next,  hover your mouse to Odin’s AP button then click it and locate the N900TUVUDNE6_KERNEL.tar.md5 and then load it.

Root t-mobile Galaxy Note 3 N900TUVUDNE6 with towelroot

Once the NE6 kernel is loaded simply click Odin’s start button and wait until it finishes and the phone restarts.

Step 2: Install Towelroot

Once your phone boots up, run  the towelroot app and then click that “make it ra1n” button.


Wait a few seconds until it install and then do reboot your phone so the new installation can be saved perfectly.

Step 3: Restore back the latest Kernel version

Doing this step is mostly important part to get rid of undesired issues as the kernel should be restored to its corresponding firmware build numbers. Let’s say if you have the 4.4.2  N900TUVUDNF9 then you only need to install back the N900TUVUDNF9 Kernel . Same goes on if you are still have N900TUVUDNF4 or N900TUVUDNF1 and any newer updates.

All you need is repeat the process from step 1. Power off the phone, then press and hold down the Volume Down, Home and Power button at the same time. Then let go of the power button when you see the message that ask you to press Volume Up to continue.

Connect your Galaxy Note 3 to the computer via USB cable. See Odin’s ID:COM bar, it should turn to blue color and shows you the USB port number of your Galaxy Note 3 connection with the computer. There is also a word that says “Added” in the log-cat box. If you ain’t see any response, try to recheck the USB cable and re-install the USB Driver.

This time load the N900TUVUDNF9_KERNEL.tar.md5 on Odin’s AP button or any other kernel build that match your current 4.4.2 OS.

Root t-mobile Galaxy Note 3 N900TUVUDNF9 with towelroot

Once loaded simply click Odin’s start button and wait until it finishes and the phone restarts.

Lastly, run SuperSU so you can see if it installs correctly, you might  see errors here all you need is grab the latest SuperSU from Play Store

(if it’s not in your app drawer, download it from the play store) and if it asks to update the binary, choose the normal method. (if it says installation failed, just try again or try again after you flash back to NF9, it’s normal and it’ll be updated)

Now once boots up run SuperSU app on your App drawer so you can update its binary.

That’s all!  You should now have a successfully rooted your Galaxy Note 3 SM-N900T, which is a T-Mobile version. Just share to us if this root method has perfectly worked on your Note 3 device.

17 thoughts on “How to Root T-Mobile Galaxy Note 3 SM-N900T Without Tripping KNOX Warranty Counter”

  1. Yeah, this rooted my SM-N900T alright, but rendered it nearly unusable due to constant warnings that “S-Pen Input Has Stopped”. Fortunately, I was able to return to stock by downloading the stock rom somewhere and using Odin to reinstall that (no CSC file required). I’ll be taking a different route to root, but thanks for wasting my time…

  2. Rooted easy on my first try, although I have rooted a few other phones and have experience with Odin. I double checked and the Knox counter was not tripped but the Device Status does show custom. installed TWRP via goo manager.

    1. I’ve now noticed a boot loop issue. Every time I reboot my phone it boot loops but if I pull the battery it works fine.

  3. When I go to settings, security, I don’t see Reactivation Lock. I never gave Knox Admin rights and I have never used the Knox app. Could that be the reason I don’t see the Reactivation Lock under settings/security??? Do I have to activate Knox??? I have the exact model number mentioned above in your instructions. Can anyone help me???

    1. That screen appears when you reset the phone. Should you reset the phone? I don’t know. Will this screen appear for this phone? It should, but I can’t garantee. But that screen pops up when phone has completed a factory reset.

      You will not see that screen anywhere else, unless you factory rest the phone. That I’m sure of.

      I went to my settings and couldn’t find it either.

      I don’t believe there is another way to disable it but to factory reset it and then have that screen show up.

  4. I take a different approach and just kill and remove Knox entirely first from the loaded rom, then from the kernel. Doesn’t really matter tripping the knox 0x1 flag because by the time I am done, the flag no longer exists in the phone and everything is very nicely standard normal non-custom or so it thinks anyway. It is a good idea to rip out the protected container spaces as well. Honestly not really all that difficult to do either. I hate Knox, typically the very first thing I go after.

    1. That sounds easy if you know what you are doing. And also sounds like the best choice since they can’t void your warranty for something that doesn’t exist. Make a procedure for it and either publish it or give it to someone. It would get a lot of traffic and appreciation. Let me know if you would like for me to distribute it for you.

  5. Worked perfectly on my Galaxy note 3 following instructions for the updated kernel of 4.4.2. i am on N900TUVUENK3 and it works great! Thanx!
