Samsung recently started rolling out the Android 4.1.2 Jelly Bean update (build number XXDLK7) for the 4G LTE version of the Galaxy Note 2 with the model number GT-N7105. Although the firmware update was first available with a Vodafone South Africa branding, it is now reported to work in a number of countries including the UK.
It should be noted that Samsung Galaxy Note 2 LTE N7105 is the version that supports LTE on 800, 1800 and 2600 MHz bands. This should not be confused with the international 3G/HSPA-only version.
Now, if you are an owner of the said Galaxy Note 2 version and have already updated your device with Android 4.1.2 Jelly Bean (XXDLK7), the next thing you would most likely to do is to root the device.
Rooting your device is required if you want to install apps that need root permission or want to install a hack or ROM.
Below are the steps to root Galaxy Note 2 4G N7105 running on N7105XXDLK7 Android 4.1.2 Jelly Bean firmware. But before going ahead, you must be aware of certain crucial aspects:
- The process is meant only for Galaxy Note 2 LTE N7105. Therefore, the users are advised to check their device’s model number in: Settings > About phone.
- Make sure the device has at least 80 percent of battery power.
- Back-up all your important data.
- The device should be a factory unlocked one.
- Once the device is rooted, it will void the warranty. But you can reclaim that by applying for official firmware update.
