CF-Auto-Root Grand 2 SM-7102
Here is the tutorial on how to root Jelly Bean 4.3 Android on Grand 2 SM-N7102 Using CF-Auto-Root:
Step 1: Download and extract the following files:
- Install the USB driver with USB debugging enabled from the Developers Tool
- Make a necessary backup of any important data.
- Make sure your device has enough battery juice in it (80%)
You should get a .tar.md5 file within extracted folder. Extract Odin zip file and you will get Odin3 v3.09.exe along with few other files. You could use any extracting software such a WinZip, Winrar or 7zip to extract files.
Step 2: Put Your Phone In Download Mode
Now turn off your phone and wait few seconds for vibration to confirm complete switch off. Then boot it into the Download Mode. To do that press and keep holding the Volume down and Home button at the same time, with these two buttons pressed press the Power Button all simultaneously. When a warning message is displayed press on the Volume Up button to continue to the process.
Step 3: Run Odin
Now run Odinv3.09.exe in as an Administrator because an Admin privilege is required to complete this installation process without any hiccups. Now connect your phone with your PC using USB cable. Once you connect, you will see a message under Odin’s message box in the bottom left-panel displaying “Added”. You should also see ID: COM port with a number and colored box in Yellow/Blue i.e. if you successfully added your device, if not then you can do the following Steps:
- Re-start the same procedure.
- Try Uninstalling and then re-installing the drivers again and restart you pc.
- Use different USB cable.
- Ensure KIES is not running in the background.
- Disable Your Antivirus.
- Uninstall or disable any program that may be causing conflicts such as your OEM’s PC Suite or any other third party software.
- Step 4: Staring the flashing process
In Odin, make sure Auto Reboot and F. Reset Time checkboxes are only two that are selected. DO NOT SELECT ANY OTHER OPTION! Click the AP button and select that file CF-Auto-Root-ms013g-ms013gxx-smg7102.tar.md5 you downloaded earlier in Step 1 with extension .tar.md5. Now, once you are ready, hit the START button to begin the flashing process. This process may take a minute or two to finish. Please do not disconnect your phone once Odin sets in motion. As the installation process completes, your phone will reboot itself and you will see a PASS message with green background in the left-most box at the very top of the Odin. You can now unplug the USB cable to disconnect it from the computer.
Voila, You have successfully rooted your phone
