  STEP 0: CHECK DEVICE MODEL NO.

To make sure your device is eligible with this, you must first confirm its model no. in ‘About device’ option under Settings. Another way to confirm model no. is by looking for it on the packaging box of your device. It must be SM-G7102!

Important Note: Backup important files stored on internal SD card of your device, so that in case a situation arises requiring you to do a factory reset after rooting your device, which might delete internal sd card too, your files will remain safe on PC.

  1. Extract/Unzip the Odin zip fileLatest Odin_ v3.09.zip on your computer (using 7-zip free software, preferably) to get the following files:
    • Odin3 v3.09.exe
    • Odin3.ini
  2. Similarly download and extract the GenNxt_PreRooted_SMG7102Grand2_BalliBoxer.zip and place the Odin flashable file in the same folder in which you extracted Latest Odin_v3.09.zip (Just for your convenience, that is).
  3. Disconnect the Samsung Galaxy Grand 2 from PC if it is connected.
  4. Double-click the Odin3-v3.09.exe file to open Odin.
  5. Boot your Samsung Galaxy Grand 2 into Download Mode:
    • Power off your phone first and wait for 6-7 seconds after display is off.
    • Press and hold these 3 buttons together until you see Warning! screen: Volume Down + Power + Home.
    • You will now be in download mode.
  6. Connect your Samsung Galaxy Grand 2 to PC. Odin window will show an Added!! message in bottom left box. Odin’s screen would look like this:Odin 3.09 - Samsung-Galaxy-Odin-Device-Added-Screenshot
    If you don’t get the Added! message, here are some troubleshooting tips:

    • Make sure you have installed driver for Samsung Galaxy Grand 2 as said above in ‘Before you begin..’ section.
    • If you have already installed driver, then uninstall them and reinstall back.
    • Connect using a different USB port on your PC.
    • Try a different USB cable. The original cable that came with your phone should work best, if not, try any other cable that’s new and of good quality.
    • Reboot your phone and PC and then try again.
  7. Load the Odin flashable recovery file into Odin as instructed below:
    • Click on the AP button on Odin and select the Odin flashable file (from step 2). Your Odin window should look like the screenshot below:
      root-samsung-galaxy-grand-2-odin-file
  8. Now in the Option section of Odin, make sure that Re-Partition box is unchecked. (Auto Reboot and F. Reset Time boxes remain checked, while all other boxes remain unchecked.)
  9. Double check the above two steps. (Step 7 and Step 8)
  10. Click the Start button to begin flashing, and wait until you see a PASS! message in Odin’s top left box.
  11. When you get PASS! message, your device will restart automatically. You can then disconnect your phone from PC.Odin 3.09 - Samsung-Galaxy-Odin-PASS-screenshot

If you see FAIL message instead of the PASS in Odin’s top left box, that’s a problem. Try this now: disconnect your Samsung Galaxy Grand 2 from PC, close Odin, remove phone’s battery and put it back inside in 3-4 seconds, open Odin and then repeat from Step 3 of this guide again.

Also, If device is Stuck at setup connection or on any other process, then too, try this: disconnect your Samsung Galaxy Grand 2 from PC, close Odin, remove phone’s battery and put it back inside in 3-4 seconds, open Odin and then repeat from Step 3 of this guide again.

    Without this issue, the device is running fine & smooth.

      Now a prob. You need to flash a firmware back. If you can do it yourself, then good, otherwise wait for my link, which would take some time, maybe a day.

        Oh! Thank u @Kapil for ur reply.
        1stly I want to know that if I use Triangle Away, can I officially update my os successfully? Triangle aslo shows a caution that there is a chance of bricking the device! How much chances of bricking? I’m using Galaxy Grand 2 (Model No. SM G7102), Android 4.3. And I’ve successfully flashed for rooting my device with ODIN 3.09 two days ago.
        And finally my 2nd quary is if I update my os with KitKat 4.4.2 with ODIN, will my device get back its official update facility? Will the root facility then available? As already having a rooted device, can my root facility will continue with the next update automatically or will it be again rooted?

        Pls reply Sir…
