Manually Update Galaxy Note 2 LTE N7105 To XXDMB3 Official Android 4.1.2 Jelly Bean Firmware

With the rumors ascending a few weeks back regarding the expected release of Sammy’s next generation phablet following the recent release of the Galaxy S4, Samsung has also started to seed the planned Android 4.1 Jelly Bean update to the successor of the all time blockbuster phablet, the Samsung Galaxy Note 2. For those who got the notification pop ups on their screens, you can get you phone update via Kies and those had rooted their phones on the previous firmware can get it done via the traditional Odin method.

If you have been following our previously tutorials on unrooting/updating your Samsung devices via the Odin method, this ride won’t be that bumpy on the run to you. Further, this is an official update installation package from Samsung and hence, no Custom recoveries can be used or it’ll rather be some junk/garbage data that might get flashed onto your phones which cause potential bricking too!

Pre-Installation Tasks:

  1. Back up all apps using ASTRO File Manager. You can get the APK files using ASTRO and later restore it. Rooted users can use Titanium Backup which also backs up data along with the apps.
  2. Back up all contacts to SD card.
  3. Backup SMS on Android.
  4. Backup call log on Android.
  5. Have minimum 60% charge on your phone else you might get stuck while the update process is running on your device.
  6. Remove any security or Anti-virus app if you have them installed.
  7. Enable USB Debugging. This can be don by Settings>Applications>Development and making sure that USB Debugging is checked.
  8. Make sure your phone is not locked to any network!
