These are the instructions to root Samsung Galaxy Grand 2 smartphones with the model number SM-G710L running on the Android 4.4.4 KitKat update. The guide uses the Odin flashing tool made by Samsung developers but never officially released. In addition to the Odin flashing tool, it utilizes the CF-Auto-Root one-click rooting package by Chainfire which installs and enabled SuperSU on your Galaxy Grand 2 smartphone.

REQUIREMENTS

• You must have the Samsung Galaxy Grand 2 LTE-A smartphone with the SM-G710L model number to use this guide without bricking the smartphone. You can double-check what model number comes with your Samsung Galaxy Grand 2 smartphone by tapping on the Menu > Settings > About Device > Model Number.
• The CF-Auto-Root package in this guide is based on the KTU84P.G710LKLUBNL1 firmware and Android 4.4.4 KitKat. We recommend you run Android 4.4.4 KitKat to use this guide, but you do not need to be running the same KTU84P.G710LKLUBNL1 firmware.

BEFORE WE BEGIN

• Unlock the Developer Options menu if it is hidden by tapping on the Menu > Settings > About Device > Build Number 7 times.
• Enter the Developer Options menu on your Galaxy Grand 2. Enable or switch on the USB Debugging Mode by tapping the options in the following sequence: Menu > Settings > Developer Options > USB Debugging Mode.
• Download and install the Samsung USB Drivers on the computer for your Samsung Galaxy Grand 2 smartphone.
• You must have a computer that is running Windows operating systems to use this guide. The Odin flashing tool will not flash your CF-Auto-Root packages on OS X or Linux.

HOW TO ROOT SAMSUNG GALAXY GRAND 2 LTE-A SM-G710L RUNNING ANDROID 4.4.4

1. Download the CF-Auto-Root package for the G710L on Android 4.4.4 from this link.
2. Download the Odin flashing tool from this link.
3. Extract the files on the desktop of the computer.
4. Boot the Samsung Galaxy Grand 2 smartphone in download mode.
5. Connect the Samsung Galaxy Grand 2 smartphone to the computer with the USB cable.
6. Click the PDA or the AP button that you can see from the Odin flashing tool’s user-interface.
7. Upload the CF-Auto-Root tar.md5 file for the Grand 2 that is on your desktop.
8. Do not make any changes to the default settings you get from the Odin user-interface, including the Auto Reboot.
9. Click the Start button and wait for the Odin app to apply the rooting file on your Samsung Galaxy Grand 2.
10. Look at your Grand 2’s screen in a few minutes for when it says it is about to reboot in 10 seconds and then watch as it boots in the recovery mode.

Any Samsung Galaxy Grand 2 smartphone that does not boot into the recovery mode will need to get in recovery using the hardware buttons. Press and hold the Volume Up + Home + Power buttons when the smartphone is off and it will boot in the recovery mode.

Report any Samsung Galaxy Grand 2 devices that are not booting to Chainfire via the official XDA Developers thread that is made for the CF-Auto-Root tool. Sometimes new software updates on your devices can bring in new bootloaders and Chainfire needs to update the files when that happens. The changes will be made automatically in our files due to the fact that we are linking directly to Chainfire’s files.
