If you have your T-Mobile Galaxy Note 3 (SM-N900T) rooted before but now you already received or updated to the new Android 4.4.2 KitKat software update. So you’ve lost root, then wondering now how to manage and root it again, this is for you. Just read the whole rooting process below as you may need to refresh some important matters before proceeding or attempting to root your device.
Things you may need to know first before thinking to root your device.
Rooting Samsung phones lately that already runs on latest Android OS such as Android 4.3 (Jelly Bean) and the new Android 4.4.2 (KitKat) will now triggers KNOX warranty void flag counter from “0x0” to “0x1”, of-course there are no exemption to this new policies and this also include the T-Mobile’s Galaxy Note 3 SM-N900T 4.4.2 KitKat update
If you are an advance users who already knows about this, then maybe you need to skip this simple reminder. This is only for beginners who did not knew the risk and downsides of rooting their phone.
What is KNOX and how it get tripped?
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 install 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 again, if you are aware with that new Samsung and your network providers policy, then you must think first before rooting your device.
