How to root Samsung Galaxy Grand 2 LTE SM-G7105 on Android 4.4.2 [Guide]

samsung-galaxy-grand-2 [1]These are the instructions to root Samsung Galaxy Grand 2 LTE SM-G7105 smartphones running on the Android 4.4.2 KitKat software update.




  1. Download the CF-Auto-Root for the G7105 on Android 4.4.2 from this link [3].
  2. Drag the zip file over to the desktop and extract the file on the desktop.
  3. Double-click on the Odin executable file that is on the desktop and your Odin flashing tool will open.
  4. Turn off the Samsung Galaxy Grand 2 smartphone and reboot it in download mode.
  5. Connect the Samsung Galaxy Grand 2 smartphone to the computer using the USB cable you normally use to charge the battery.
  6. You should see the “added” message from the Odin app on the computer if your device is connected properly.
  7. Click the PDA or the AP button you can see from the Odin flashing tool’s user-interface.
  8. Browse the desktop location for the file ending in tar.md5 for your Grand 2 LTE smartphone.
  9. Do not adjust any of the default settings of the Odin flashing tool on your computer.
  10. Click the Start button and Odin will flash the rooting exploit on your Samsung Galaxy Grand 2 LTE smartphone.
  11. keep watching the Grand 2’s display for when it tells you that the device is about to automatically reboot in about 10 seconds.

The Samsung Galaxy Grand 2 LTE smartphone will now reboot automatically in recovery mode; this is an important part of the process and without it the guide will not have worked in successfully rooting your device. Anyone who does not get to recovery mode can manually get there instead by holding the Power + Home + Volume Up buttons during the booting process. It only works on the Grand 2 if you start with the device off first.

Sometimes new software updates that roll out for the Samsung Galaxy Grand 2 can bring new bootloaders. When that happens it is possible that the device will not boot because Chainfire hasn’t yet updated the necessary files to deal with the new bootloaders. You can report any devices that are not booting over at the official CF-Auto-Root thread [4] at XDA Developers.
