Galaxy Note 2 users, who failed to update their device to latest N7100XXDMG1 using official method for being region specific, may follow our step-by-step guide to install the same manually using Odin flashing tool. The XXDMG1 build is an unbranded version of firmware and can be installed on any unlocked GT-N7100 unit except those which are from China, Hong Kong and Taiwan.

IBTimes UK reminds its readers that it will not be held liable for any damage to the device. Before installing the official firmware, users are advised to verify that their devices meet following requirements.


1) Install USB Drivers for Samsung Galaxy Note 2 to connect the Android device with computer.

2) Enable USB Debugging Mode on phone to connect it with the computer and use Android SDK with it. [Press Menu>> Settings>> Applications. From there navigate and click on Development option then check USB Debugging Mode.]

3) As the tutorial is likely to wipe out all data of the phone, create a backup. If the device is having any custom recoveries such as CWM/TWRP installed then backup data using the recovery.

4) The Galaxy Note should have charge above 80% battery charge.

5) The device should be factory unlocked and not locked to a particular carrier.

6) The phone will lose custom ROM with the installation of official firmware. Also, the custom recovery will be replaced by the stock recovery.

7) The device will no longer belong to a rooted version once official firmware is installed.

8) XXDMG1 Android 4.1.2 official firmware works only with Samsung Galaxy Note 2 GT-N7100. As flashing this on any other variant might brick the device, verify the model number of Note 2 by navigating to Settings>> About phone>> Model number.
