Galaxy Note 2 model number N7100 has a new firmware update available, and you can use this tutorial to learn how to successfully install it on your smartphone. Read the entire post and make sure not to skip any steps that are listed below.

This update brings some tweaks and improvements to your device's OS so that you won't experience any more problems while using it. We can't guarantee that this new update doesn't have any bugs or problems but, early reports are stating that the phone is more stable and that the battery life stays the same as it did on previous builds. In order to make sure that you successfully flash this firmware update, read the guidelines below.

Here's what you need to know and how to correctly configure your Galaxy Note 2 N71000 for the Android 4.1.2 XXDMB6 installation process:

  • This tutorial will work with the Samsung Galaxy Note model number N7100. Your device has to be factory unlocked. Don't use the XXDM6 firmware files on any other Android device.
  • You will be able to flash this update over stock Android 4.0 / Android 4.1 Jelly Bean OS. Don't try to flash this update over a custom ROM as it won't work and you will brick your device.
  • If you're running a custom ROM on your N7100 device, then you will be forced to restore it to a stock Android 4.1 firmware.
  • Backup all data stored on your device before applying this update. If your phone is on stock Android then you won't lose data but, it would be best for you to have backups of your most important data files.
  • Enable USB Debugging option from the Settings menu.
  • Also, make sure that your computer has all the Samsung USB Drivers for Galaxy Note 2. Without these installed you won't be able to flash the firmware update.
  • The battery of your device should be charged and its power level showing at least 50%. This will prevent the phone from powering off during installation process.
  • Read the entire post before starting the update and make sure that you don't skip any steps that I have listed below.
  • Don't blame us in case something goes wrong and you lose important data or you brick the device. Use the comments section to ask for extra help in case you cannot complete the tutorial.

Now that you know all of the above, you can continue to the next part of this post.

How to update the Galaxy Note 2 N7100 to Android 4.1.2 XXDMB6 Jelly Bean build:

  1. Download the XXDMB6 firmware zip from HERE. Save the file to your PC. When the download is complete you have to extract its contents and save into a single folder.
  2. Download ODIN zip from HERE. Save the file and then extract its contents when the download is complete.
  3. Power off your Galaxy Note 2.
  4. Boot it into Android Download Mode by pressing and holding at the same time Volume Down, Home and Power. Release the buttons when the Download Mode appears.
  5. Now, launch Odin executable from the Odin folder.
  6. Connect your device to your PC using the USB data cable. ODIN will display a confirmation message that says 'added!!'. Get to the next step.
  7. Click the 'PDA' button in Odin.
  8. Browse your computer for the XXDMB6 .tar.md5 file and load it into ODIN. Do not change any other default settings.
  9. Press the START button when you're ready for the updating process.
  10. The Update to Android 4.1.2 JB shouldn't take more than 5 minutes. Wait until ODIN completest the install and you phone reboots.
  11. The SGS Note 2 will boot into normal mode and that should be all.

NOTE: If ODIN gets stuck or it shows the FAIL alert, then you should disconnect the phone from PC. Close ODIN, power off the device by removing its battery. Re-insert the battery when 5 seconds have passed and then you should launch again ODIN and repeat the entire tutorial once again starting with step 4. The update should be installed at your second attempt. If you have any other problems ask for more help in comments.

NOTE2: In case ODIN displays the PASS message but, the phone doesn't go past the Samsung boot logo animation  after 15 minutes have passed, then you will be forced to boot the Stock Recovery mode and 'factory reset' your device. Read the guidelines below to learn how to wipe the data from your phone's /system partition:

  • Power off the Galaxy Note 2 device by removing its battery. Re-insert the battery after a couple of seconds have passed.
  • Press Volume Up, Home and Power buttons simultaneously. This will take your phone into stock Recovery mode.
  • Select 'wipe data/ factory reset' option and confirm this process.
  • Return to the main menu of the Recovery mode and select 'reboot system now'.
  • Wait several minutes before the Galaxy Note 2 managed to boot into Android 4.1.2 Jelly Bean XXDMB6 OS.

That's it, these were all the instructions that you had to go over in order to update your smartphone.
