A new 4.4.2 KitKat update Galaxy Note 3 SM-N900 (Exynos)with build number N900XXUDNB2, just recently rolled out by Samsung this month.  Though after the first 4.4.2 KitKat N900XXUDNA6 on January, yet there are still among Galaxy Note 3 N900 users who did not received or enjoyed the KitKat update.  Since software updates comes and the release is in waves and not wide spread that simply means not everyone  get an update at the same time.

For about this time another 4.4.2 KitKat firmware build dubbed as N900XXUDNB2 for which can be seen hitting in select countries only, such as Russian Federation, Ukraine, Uzbekistan and Kazakhstan. These mentioned countries already received the first 4.4.2 update on January and it soundly seems that this update has been ironed out for improvements, bug-fixes and any similar issues found from the first released (N900XXUDNA6).

This update is now live via Samsung Kies, you may only need to fire-up that Kies 3 in your computer then check for this update if it happens that those mentioned countries is one of your homeland.

For those who did not seen how the Android 4.4.2 KitKat looks like, here’s the video of a Galaxy Note 3 with 4.4.2 KitKat in action.

Important Reminders before Flashing Stock Firmware

Will this trip KNOX warranty void flag counter to 0×1?
Nup, this a official and signed firmware from Samsung, so flashing official firmware will not trip KNOX.
My Galaxy Note 3 is rooted, will I lose root?
If your device is currently rooted you will lose root after flash, but you can still root it again anytime you want.

Disclaimer: Use of this method is solely at your own risk! Please proceed with precautions, for we will not take any responsibility if anything happens to your device by using this guide.

  • Make sure that your Galaxy Note 3 battery is fully charge.
  • Stock Firmware packages comes in two formats the ‘Full-Wipe’ (delete your stored data after flashing) and the ‘Non-Wipe’ (it doesn’t delete your phone’s stored data) but it is highly recommended to make a back up all important files stored from your phone’s internal memory – contacts, messages, etc.  before flashing no-matter if it is Full-Wipe or Non-Wipe,  just to be safe and ensure that your stored data are in  safe  if something went wrong during the flashing process.
  • Use a PC or laptop that runs in Windows OS, with a good and perfectly working USB serial-port.  Odin will not work on MAC OS.
  • Use the supplied USB cable for your Galaxy Note 3.
  • Enable USB debugging from your phone’s settings – while if you are on 4.3 just hit Settings>About Phone> then scroll down to the build number and tap that number for around 7-times ’til the Developer option appear.
  • Ensure that KIES is closed and not running in the system tray! Kies and Odin are both created by Samsung but Kies will interrupt and doesn’t like Odin, it will block you from flashing.

The Android 4.4.2 KitKat now comes with a new protected bootloader that might cause issues when you try to downgrade to the old software updates. This also applies if you are planning into rooting and installing any custom recovery and any unsigned firmware once you are on 4.4.2 KitKat, so please be aware with that.

Install the USB Driver first to get rid of flashing failures. Also, you need to extract the downloaded file which is packed in zip or rar files, so that you’ll get the tar.md5 file.

Run and Configure Odin

Run Odin downloader Odin3_v3.09 on your PC desktop. Watch out the check-boxes options on the right top of Odin, ensure that the‘Phone Bootloader Update’‘AUTO-REBOOT’ and ‘F.RESET TIME’checkboxes must be checked. Only the ‘RE-PARTITION’ is unchecked.

Reboot your Galaxy Note 3 into Download Mode

To reboot the Galaxy Note 3 into  download mode , you need to turn the power off.  After it completely shut off,  just  press and hold the Volume Down key,  Home button and the Power ON/OFF button simultaneously.

You should then prompted into a warning screen and asking you  to press volume up if you want to continue or volume down to cancel, just simply press volume up to get into download mode. The download mode then displays an Android robot and say’s “Downloading.. Do not turn off target!!”

Connect your Phone to PC or Laptop

Once you already reboot the phone in download mode,  simply connect the phone to your PC or laptop USB.
In Odin window – the ID:COM box will turn to blue color and indicates the COM port number and a word “Added” on a log box will prompt you that the device is already detected or recognized by Odin. Your COM port number might be different from mine. If you do not see a COM port number then there’s something missing or wrong. You may read again from the top of this post.

Load the stock 4.4.2 N900XXUDNA1  KitKat firmware file

The stock firmware is pack in a single .tar.md5 file only.  Now, you need to just simply click on the AP button, then browse to the folder where the file you have previously extracted and then select and load it.
“N900XXUDNB2_N900SERDNB2_N900XXUDNA1_HOME.tar.md5″

Start Flashing or Installing the stock firmware

Once if all set and ready to fire-up, hit the “START” button in Odin to begin flashing the stock ROM.
Do not ever interrupt the phone while already in flashing progress, like disconnecting the cable or turning the device off. Just wait until it completely finish.

Wait ’till it PASS!!

When the Stock Firmware installation successfully completes, you will then see a word “PASS” in Odin. This indicates that the flashing was already finish, and on the log box it says “All threads completed  (succeed 1 / failed 0)”. The phone will just then automatically reboot, then it’s about time to remove it from PC or laptop USB connection.

Confirm if you successfully installed the stock firmware

Confirm your fresh firmware installed by typing *#1234# or
Go to Settings>About Phone>Firmware info.
You can also do factory reset by dialing *2767*3855#.

Possible errors that you may encountered, this is based on my own experience while flashing stock firmware on Samsung Android devices. These are just a few hints on how to resolved it.

Q: I got an error message that says “Set-up connection Failed” ?
A: 1. Check your USB connection from the phone to PC,
2. Connect to another PC USB port
3. Check and or try to another USB cable
4. Re-install the USB driver.
Q: Odin just suddenly stuck in the middle of nowhere while in flashing progress, it isn’t responding at all?
A: Check for possible program that might interrupt the process, like disabling the anti-virus and closing any running programs. Also try to use another computer or laptop,
Q: I experienced bootloop or the phone just stuck on Welcome Logo (phone always stop at bootanimation) and it won’t boot normally?
A: This eventually happens if your device came from custom firmware but you can fix it via recovery mode option, do this:
Boot in recovery mode
1. Press and hold Volume Up, Home and Power button.
2. Use volume keys to select, Up and Down and Power or Home key to select the option
3. Select Wipe Data/Factory Reset using the Home button.
4. Next select the Wipe Cache Partition
5. Lastly, select Reboot System Now to reboot your Galaxy Note 3 in Normal mode.
