The latest Jelly Bean update for Galaxy Tab 2 7.0 P3110 (Wi-Fi) is now available via recently released Android 4.1.1 XXCLL3 official firmware from Samsung. Those who have already updated their tablet with this official firmware can now install root access on it by using CF-Auto-Root with ODIN flash tool.
NOTE: The CF-Auto-Root method does not install custom recovery tools such as CWM Recovery. Instead, the root package installs SuperSU access and root binary features. CF-Auto-Root is the quickest and easiest method of rooting for beginners and helps in preserving the stock firmware settings to deliver pure stock-Android experience.
- Verify that the correct USB drivers are installed for your Galaxy Tab 2 on the computer. Download Galaxy Tab 2 7.0 P3110 Wi-Fi USB drivers.
- Users are advised to back up important data and settings to avoid data loss while flashing the CF-Auto-Root tool on your tablet using ODIN. It is recommended that you back up data using custom recovery tools such as ClockworkMod (CWM) or TWRP recovery.Avoid using Samsung KIES or ROM manager for data-backup, as it may permanently damage or brick your device.
- Enable USB Debugging mode on your tablet by navigating to Settings > Developer Options (if the device is running Android 4.0 or later). Else go to Settings > Applications > Development (if the tablet is running Android 2.3 or earlier).
- Make sure that your tablet has at least 85 percent battery power to prevent unexpected device shutdown (due to battery drain) while flashing the CF-Auto-Root tool on XXCLL3 official Jelly Bean firmware.
