[T-Mobile Samsung Galaxy Note 3] sfwasabi:
I confirm, my T-Mobile Samsung Galaxy Note 3 N900T is rooted to Android 4.4.2 KitKat without tripping Knox. Knox is at 0x0.

I successfully did it following only this thread without having to read the German website.

These instructions require your phone to ALREADY be rooted. It allows you to KEEP the Root access you already have and upgrade to Android 4.4.2 KitKat without losing your Root access. Your phone must be rooted FIRST!

REQUIREMENTS:

1- Purchase and install Mobile Odin Pro from the Google Play Store.

2- Download Odin that has the BL (bootloader) button from http://xdaforums.com/attachment.php?attachmentid=2551152&d=1391196733

3-

A) IF YOU HAVE A US T-MOBILE Galaxy Note 3 N900T, THEN download the Bootloader (N900TUVUCNB4_BL.rar) referenced in http://xdaforums.com/showthread.php?p=50963302

OR

B) If you DO NOT have a US T-MOBILE Galaxy Note 3 N900T, then the Bootloader above will not work for you. You must build your own using the German instructions at http://www.mobtivity.com/de/news/galaxy-note-3-update-auf-android-kitkat-mit-root-und-knox-0x0.html You can go to http://translate.google.com and copy that link into the input box and press the button to have Google translate the website for you.

4- Download N900TUVUCNB4_N900TTMBCNB4_N900TUVUCNB4_HOME.tar.md5 Size: 2.07 GB (2,230,825,042 bytes)]

5- Download CSC.tar referenced at the top of this thread.

N900TUVUCNB4_N900TTMBCNB4_N900TUVUCNB4_HOME.tar.md5 will be copied to your phone and used by Mobile Odin. All other files will be used by Desktop Odin on your computer.

OVERVIEW:

When you upgrade to the stock KitKat ROM without following the instructions in a guide like this, you will lose Root.

This guide allows you instead to hijack the phone before it finishes booting to install a custom BootLoader which put Root back into the phone before the phone finishes the first boot.

The settings you put into Mobile Odin will perform 2 functions. 1. It flashes the 4.4.3 Kit Kat ROM onto the phone and 2. IT SETS THE PHONE TO REBOOT TO DOWNLOAD MODE (<-IMPORTANT!!!) and NOT to reboot normally.

Once KitKat is flashed, Mobile Odin reboots the phone into DOWNLOAD MODE, THEN you can use Desktop Odin, CHECK AutoReboot AND Phone BootLoader Update, to insert a custom bootloader which will allow you to keep root.

Once the bootloader is flashed, the phone will boot up normally. I immediately shut the phone down, put it into download mode, and flashed the CSC.tar file into the CSC button on Desktop Odin with the only option checked is AutoReboot.

STEPS:

1) Safety: Remove your SDCard, backup your phone, etc.

2) De La Vega Root Method (<- Skip if your phone has already been rooted)

Since my phone had already been rooted with the Root De La Vega method and was running Jellybean, I skipped Step 1.

3) Copy new Stock Rom to Root of Phone (N900TUVUCNB4_N900TTMBCNB4_N900TUVUCNB4_HOME.tar.md5 [Size: 2.07 GB (2,230,825,042 bytes)])

Your phone needs to be rooted before you can copy the ROM to your phone. My phone would not allow me to copy the file to the root directory (/), so I copied it to the sdcard directory (/sdcard)

4) Flash with Mobile Odin Pro (Keeping Root), and set to reboot in to Download Mode

Start Mobile Odin Pro:

i) Scroll to Open File... and click it.

ii) Find the N900TUVUCNB4_N900TTMBCNB4_N900TUVUCNB4_HOME.tar.md5 file from whatever directory you copied it to on your phone.

iii) Scroll to EVERROOT and ensure the following are checked

a. Enable EverRoot

b. Inject Superuser

c. Inject Mobile ODIN

iv) Scroll to WIPE

a. Ensure "Wipe Dalvik cache" is checked

v) Scroll to After wipe... and click it.

vi) Select Download mode and click the back button.

viii) Leave all other settings as they are.

iv) Scroll up to where it says "Wipe Start the wipe procedure" and click it.

This will flash KitKat onto the phone and reboot the phone into Download mode. Once the phone is in Download mode...

5) In Odin (Desktop Version) Flash the File in post 3 of the thread I mentioned at the start

i. Open ODIN on your computer.

ii. Verify your phone is connected to your computer and recognized by Odin with a COM Port number under ID:COM and ADDED! message in the messages window.

iii. Check Auto Reboot

iii. Click the BL button and select the bootloader from wherever you saved it on your computer.

a) If you are using the T-Mobile Galaxy Note 3 N900T, use the N900TUVUCNB4_BL.rar bootloader referenced above.

b) If you are not, use the bootloader you created following the German instructions.

iv. Check Phone Bootloader Update.

v. Verify everything looks like http://www.mobtivity.com/images/news/Tutorials/Note3-Knox0/Odin.jpg and click Start button.

6) Phone will reboot. Then turn it off and set it to download mode ( Press Power, Home and Volume Down buttons at the same time).

7) Once the phone is in download mode...

i. Open ODIN on your computer.

ii. Verify your phone is connected to your computer and recognized by Odin with a COM Port number under ID:COM and ADDED! message in the messages window.

iii. Check Auto Reboot

iv. Click the CSC button and select the CSC.tar file from wherever you saved it on your computer.

v. Verify that only Auto Reboot is checked, and all buttons are blank except for the CSC.tar file beside the CSC button, then click Start.

After CSC is flashed, phone will reboot into KitKat with Root! Give the phone a little time for everything to load. Checkroot gave me a heart attack by stating I didn't have root access, but it was only because the phone hadn't fully booted up yet!
