This is a tutorial for noobs or members who are new to Rooting and want to root their phone.

Downloads:
*Odin 3 v3.0.9
*CWM recovery thread(Downloads available for 4.3 and 4.4 also)
*SuperSU

Steps to root your phone:
1) Download the first two files given above to your laptop/PC.
2) Turn off your phone.
3) Go to download mode (by pressing Vol.down+home+power buttons at the same time for about 7-8 secs)
4)Open the ODIN file you downloaded on your laptop/pc.
5) Connect your phone to your laptop/PC through USB cable(do I have to tell that :p)
6) When ODIN detects your phone, the ID:COM area will become yellow/blue
7) In ODIN click on PDA and then select the recovery file you downloaded. Also tick the check box beside PDA(if there is any)
8) Click on start. The flashing process will start.
9) If the flashing succeeds, ODIN will show 'PASS'. That means the recovery flashed successfully. Yay!!!
10) Now turn on your phone and download the third file and place it in your external SD card.
11) Turn off your phone.
12) Reboot to recovery(by pressing Vol.up+home+power buttons).
13) The recovery will start. You have to navigate by volume buttons and power button.
Vol.up - move up
Vol.down - move down
Power button - select option
14) Select 'install zip'.
15) Select 'Choose zip from ext_sd or external SD card'.
16)Select the third file you downloaded. Flashing process will start.
17) After it finishes, go back and reboot your phone.

It's upon you, of you want to follow this:

18)Use Knox Remover to remove all Knox files.

Enjoy your rooted Galaxy grand 2!!! Now you can flash other recoveries or flash other custom ROMs or custom kernels.

Some useful tips(Experimental/WIP):
You can use Triangle Away to reset the flash counter after flashing ROMs and make your device status from custom to official. This is a really useful app. Report here if it works. You needn't download from google play, you can scroll down and download from the attachments.

I did what was in description,, It didnt work on 4.4.2, but it has modified the phone,, as when I try update it says phone has been modified, try to update through kies...
you need to flash supersu in recovery, load up supersu when you have rebooted and have it disable knox, then reboot into recovery and reflash supersu and youll be rooted.

I used towelroot v1 to root my G7102 on JB 4.3

I flashed the indian stock rom to get the update to kitkat and now downloading the update for kitkat

after updating I will test towelroot on 4.4.2 and post results

Have you tested it?
I don't have this device, but I think shabbypenguin is right. Follow that method for kk. I'll update the thread, once kk recovery is released.

Similar, I'm in teh US with a nexus 5, in no way shape or form will i ever hold this device in my hand so no way for me to test it out.

there will be no kitkat recovery, the mere fact he booted to recovery and was able to flash the supersu means that is is working. the cwm i put out is already compatible with 4.4

I had even flashed the super user it failed saying couldn't verify signature. When u boot in recovery it doesn't say CMW recovery. In the center of the screen under the logo it says no command and down in the screwn it says manual mode.

About knox I checked there is nothing I can disable. while in recovery..
I have used Cwm in s2. . So I know it's interface..

One last Question

Well then the CWM didnt flash through odin,, its funny bec Odin gave all the indication that it successfully flashed the recovery.. Just one last thing I need to know,, I am sure somehing is broken at the recovery/software level now..as when I check for software update, it says ur device has been modified,, how do I fix this.. flashing stock 4.4.2 rom?



you had stock recovery not cwm

You need to uncheck auto reboot in odin. When it finishes flashing disconnect the device and pull battery. Then put it back in and manually boot to recovery
