Getting Started To Unroot Your Galaxy Note 3 SM-N900T
Fully Recharge the Phone.
First thing first , fully recharge your Galaxy Note 3 battery before engaging into flashing process. Power interruption or failure during the flashing process might ruin your device in no time.
Back-up all Important Files.
During the unroot process it deletes all of your files that are stored from your phone’s internal memory. So make sure to make a back-up copy from all of it and save it in a very safe place.
Follow this guide: How to Back-up and Restore Files on Galaxy Note 3
- Enable USB debugging mode if you are having issues connecting your device to the computer try to enable the this option. In your Samsung Galaxy Note 3, go to Settings>> About device>> then look for the firmware build number and then tap that build number for around 7-times (e.g. on 4.3 it’s JSS15J.N900TUVUBMI7 and for the 4.4.2 KitKat it’s KOT49H.N900TUVUCNB4 and any future update build numbers) until a message pop-ups that says something “congratulations you are now a developer”.
- TURN OFF the Security Reactivation Lock – This only necessary if you already turned-on this security option from your phone’s settings. If you’ve turned it ON before, then you must turn it off for we cannot reconfigure the system if it was turned-on even Samsung personnel requires this if you want your device to be repaired under warranty. Just tap on Settings>>Security>>Reactivation Lock and then uncheck the Turn Reactivation lock on.
- Prepare a Windows base OS computer or laptop, Odin flasher tool will not run on Mac and other OSX.
- Use the supplied USB data cable, a bad USB data cable caused a flashing errors. Believe me, I’ve faced it several times, if you get failed errors in Odin then you did not read this.
- Remove the external micro SD card if you have one, to avoid any failures and error during the flashing process. (Recommended for beginners, some rouge 3rd-party apps stored on SD card may also caused some problem)
- Closed any other running programs in your computer, this include the Kies 3 which basically blocks you from using Odin.

A USB Driver – This is only needed if you haven’t yet installed the Kies 3 apps in your computer. Older USB drivers will not work on the Galaxy Note 3 because it now runs on the latest Android OS such as 4.3 and 4.4.2. Grab it here – Download Kies 3 for Samsung Galaxy Note 3 or the USB Driver. Just run the program to install it in your computer.
Check your Galaxy Note 3 SM-N900T Android version
On this step I also importantly requires this for beginners, to check for the running Android version of your Galaxy Note 3. Basically, the Galaxy Note 3 is runs on different Android versions, which comes from Android 4.3 (Jelly Bean) to Android 4.4.2 (KitKat). Without knowing this is very crucial on some part, because in later software updates Samsung has added some security measures which is hidden inside your phone’s ecosystem. One of these is the “KNOX” security platform, that once being triggered it will automatically set your device into custom, and or voids your phone’s warranty. But if you have gone this far, and you have already rooted or modified your device, you might already tripped the “KNOX” security counter. But this method will not worked to reset for that KNOX counter, this will only restore your device from rooted or custom to official state.
Checking your Samsung Galaxy Note 3 software build version is too very easy, you can simply navigate from your phone’s home screen then simply tap Menu>>Settings>>About Device.Then look for the text field that says “Android version”, it might have the 4.3 or 4.4.2 OS.
Now, once knowing the correct Android version from your phone, this will save us time and get rid of any unwanted errors. As I already mentioned that the latest Android version already equipped with high security configurations. Advanced users and developers also called this as “locked bootloader”, meaning to say, you cannot just simply install any official or unofficial firmware builds to an Android system that has a locked bootloader, or else you are just going into trouble and messed-up your phone in no time.
Select the Correct Firmware Package version
From these step it’s also been crucial if you just grab any firmware package without knowing which one is the correct version to choose. So that is why I want you to know the correct Android version first. Now, let say if you have a rooted version of Android 4.3 Jelly bean then you may only restore your device to the official Android 4.3firmware. Same as it goes if you also have a rooted Android 4.4.2 KitKat, then you may also only restores back your phone to the official 4.4.2 KitKat. If you already on 4.4.2, you cannot actually downgrade back to the old software updates like 4.3, marked my word don’t do it.
You can download one of these original firmware from here:
USA and Canada Galaxy NOTE 3 Stock Firmware Packages
Again, grab the 4.3 stock firmware if your Galaxy Note 3 runs on rooted 4.3, but you can also update that to the official 4.4.2 KitKatfirmware later on, if you want to as long you are already running on pure 4.3 firmware. And for those with rooted 4.4.2 KitKat, you only grab the official 4.4.2 KitKat firmware and please DO NOT ever Odin-back the 4.3 firmware, if you wouldn’t like to send your device to your service center or might also send it to me as I can fix it with my JTAG repair tool.
You must then select one the SM-N900T firmware package that matched with your phones OS version, If you have the rooted Android 4.4.2 then download the original 4.4.2 firmware file, same also if you still on 4.3 then grab the 4.3 stock firmware.
You also need to unzip or extract the firmware file, compressed files can be extracted using 7zip, winzip, winrar or any unzipping program you have in your computer.
Galaxy Note 3 Download Mode and Odin Flasher Tool
Step 1: Run the Odin3_v3.09 and configure Odin in your computer desktop.
Hover your mouse to these three Odin check-boxes options, by default the ‘Auto Reboot’ and ‘F. Reset Time’ check-boxes are marked checks. Just ensure the “Re-Partition” remains no check marked.
Step 2: Boot your Galaxy Note 3 into Download Mode
Turn it off, then Press the Volume Down+Home+Power buttons at the same time, then let it go until a warning screen prompted you to choose to continue or cancel. Press the ‘Volume Up button” you will then see a download mode screen.
Here is what it looks like when a Samsung Galaxy Note 3 rebooted in Odin Download Mode.
Step 3: Connect your Galaxy Note 3 to the computer via the USB data cable
Once you connect your Galaxy Note 3 with the USB cable you can see that Odin’s ID:COM triangular bar turned to blueish color and shows you the USB port number of your Galaxy Note 3 connection with the computer. The COM number will depend on which USB port assigned with your phones, it usually connects from 01 to 07. 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.
Now hover your mouse to Odin’s button.
Step 4: Reload the Firmware Package in Odin
Click the Odin’s ‘AP button‘ then browse and select the firmware file. Just make sure you already decompressed or unzipped it so you can browse it to the folder where you put it, it should it end with file description as “tar.md5″ or else the flasher program will not recognized it. Like for example if you have the 4.4.2 KitKat firmware is should look something like this, “N900TUVUCNB4_N900TMBUCNB4_HOME.tar.md5″
or the 4.3 Jelly Bean is like this,
Firmware packages comes in different build version numbers and basically shows the device model number such “N900T” which means that this firmware file is for T-Mobile’s Galaxy Note 3 SM-N900T.
Then wait a couple of seconds while it reads the MD5 checksum.
Step 5: Install Back the Original Firmware
Simply hit the “Start Button” Once both AP and CSC files filled with the right files, simply click that Odin’s “START” button to begin flashing. Wait and watch the progress bar as it will show you the exact time how it completes the flashing and it takes a couple of minutes before the flashing finishes, you have a time to relax for a while.
Step 6: Wait until the Restoration Process completes!
When original firmware installation successfully completed, you’ll noticed that Odin displays a word “PASS”. this only indicates that the flashing was successful and your Galaxy Note 3 has now being restored back to the official firmware, and your root was gone for good.
But in other situation, there is also some circumstances that you’ll get a flashing failure, this is due to a bad flashed or any other interruption occurred during the process.
If you’d get the “Fail” error, you must then simply repeat the process. You may also check any other things that might have caused the problem like checking the USB data cable, your computers USB ports and closing any other programs that might have interrupt while running Odin.
Recheck and Confirm if you’ve successfully Unroot your T-Mobile Galaxy Note 3 (SM-N900T)
Once you already Odin’ed-back the official firmware it automatically mean that your phone now fully runs with the official firmware and then it can received any official (OTA) firmware again.There is also free app from play store called root checker, you can use that too.
