How to Root Galaxy Note 2 N7105 on Android 4.1.2 XXDLL7 Official Jelly Bean Firmware [Tutorial]
Samsung releases Android 4.1.2 XXDLL7 official Jelly Bean firmware for Note 2 N7105 users in UK

Galaxy Note 2 N7105 users, who have already updated their device to Android 4.1.2 XXDLL7 official Jelly Bean firmware (step-by-step install guide), may have lost root access to their device after the update. Such users can now root their device again to regain full system access or Super User access for installing latest root-based apps and custom ROMs.

The rooting method employed in this guide makes use of CF-Auto-Root with ODIN flash tool. This root method is known to be the quickest and easiest rooting technique available today (especially for beginners), as it preserves the stock phone kernel while adding root access and SuperSU privileges for the user.

NOTE: Rooting your device will increase its binary flash counter and hence void its hardware warranty. You can reclaim the warranty on your device by just reinstalling the official Jelly Bean firmware, if such need arises. As an alternative, you may run Triangle Away app to reset the flash counter and restore the hardware warranty for your device.


    • Make sure that your phone is already running the official Android 4.1.2 XXDLL7 firmware onboard. Go to Settings > About Phone to verify the firmware version installed.
    • Users are advised to back up important data and settings before continuing with the rooting process. Data backup should be done manually using ClockworkMod (CWM) or TWRP Recovery. Avoid using either Samsung KIES or ROM manager, as it may permanently damage or brick your device.
    • Ensure that any of the custom recovery tools such as CWM or TWRP Recovery are preinstalled on your phone, before you proceed.
    • Enable USB Debugging mode on your phone by navigating to Settings > Developer Options
    • Make sure that your phone has at least 85 percent battery power to prevent unexpected device shutdown (due to battery drain) while rooting the device.
    • Verify that your phone is factory unlocked and not locked to a specific carrier to prevent unexpected damage to the device.
