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

This is a 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 0×1 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 0×1. 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.

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 0×1 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.

  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???

  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 0×1 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.
