Samsung has just rolled out its first Android 4.3 update for Galaxy Note 2 (LTE) via N7105XXUEMK5 Jelly Bean official firmware. The new firmware is now available for download as Over-The-Air (OTA) update as well as through Samsung KIES.
Those who have already updated their Note 2 LTE to the newest Android 4.3 XXUEMK5 firmware can root the same with CF-Auto-Root using our step-by-step guide given below. The CF-Auto-Root tool is developed and released by XDA recognised developer, Chainfire, which allows any Galaxy Note 2 user to root the device irrespective of the firmware installed.
