Yeah, it should work on all builds of 4.4.2. I have installed it on latest H3 firmware and it worked for me! After you have installed custom recovery, you have to flash with Super SU. The download link have been included already in the post.

Hey folks..this process dsnt work with grand 2..phone wont boot…for those whose phone dsnt boot up as normal or gets struck on between..follow ds steps.download alpha zip and insert grand 2 recovery.img into it..nd flash it with odin..done..no need to install firmware…
The rooting process does work. You can recover your phone by flashing recovery image (in case if anything goes wrong), but fresh install is usually recommended.
USELESS APPLICATION.IT DOESN’T ROOT ANYTHING.I TRIED IT MORE THAN TWICE BUT NO MATTER WHAT I DO IT ALWAYS LEADS ME TO A NORMAL RESTART WITHOUT ROOTING .ALL THIS PROGRAM DOES IS WHEN YOU BRICK YOUR PHONE, IT RECOVERS IT AND YOU CAN RESTART YOUR PHONE NORMALLY.CHECK YOUR PROGRAMS BEFORE YOU ANNOY US.GOT IT?
If you were not able to root doesn’t mean it is useless! I have rooted it twice and wordked like a charm. If your phone reboots normally, than it restores stock image. That’s why you have to disable auto-reboot option. Its not possible first time, but next time it is available provided that you do not close ODIN. Hope this helps.
done all steps…also there was a \\\”\\\”pass\\\”\\\” message but i checked the root by downloading root checker.. it was not rooted…jelly been 4.3SM-G7102what should i exactly do???
Try using towel root. It works with Jellybean.
Bhai, does it really works with samsung galaxy grand2. I recently updated mobile to Kitkat os. I need your help… .
Yes, it works on KitKat. Tried on H3 and H6 builds, it works perfectly.
can this methos work for build NI2?
Should work on I2, but since there is knox present in the new stability update, so may be it won’t work. Just try it out and report it back.
Thanks… successfully rooted 4.4.2 kitkat version.. but could you please tell me how to install philz recovery, i dont wanna take risk of bricking phone.. already soft bricked 2 times and it was so hell tiring to install original ROM.
You can flash recovery.img of philz touch recovery using flashify android app.
Do I need to do both steps to root or only d first?
Only the first step. Second is alternate step, which was available until Chainfire got updated.
Hi..ist really dont void waranty even we unroot it?
Yes, it voids warranty, if you are on latest KitKat firmware with build J2 or K1. Flashing back official firmware doesn’t in these builds work since they have Knox enabled. On H3 and H6, you can regain warranty by flashing official firmware.
Please help me. I update my grand 2 duos OTA. And now my android is kitkat 4.4.2. My problem is my sim 2 isnt working anymore. Whats happen and any solutions?
Thank u
You cleared data and cache after installing OTA update? That works.
Does this method works with grand 2 latest NK1 firmware build ?
Plz reply asap,
Thnx in advance.
Yeah it does work. Not tried myself though, just confirmed it with our group
Ya thanx rooted successfully, its works like charm but only one problem while booting into recovery mode its displays a warning or error like

Try rooting with other step. May be due to CF tool.

hey writer! I have some que to ask u before I root my sm-g7102 running on android 4.4.2 whose baseband version isG7102DDUBNI1 and build no. is KOT49H.G7102DDUBNJ2.
1). I rooted my phone 3 months ago which was succesfull and sowehow it was soft bricked after 1 month(idk how)after that i can only go to download mode. Can u tell me how it happened,i didnt tried to install any rom or anything like that,
2). Now i installed new firmware which is running on android 4.4.2 in which knox is installed. So should i do second procedure or should i disable it manually.Or i should try 1st procedure first.
3). After rooting my device will recovery booting will be kind of uninstalled?
and ya reply as soon as possible and thanx in advance.
1) It might have happened due to some app, since you have admin rights. So allow SU only to trusted apps
2) Use 2nd method to root. It works on all builds
3) It will just be replaced with custom recovery with more options than your stock recovery
Thanx a lot .Firstly i was rooted with cwm. and ten i tried to install .img file using flashify. but y recovery was gone . i done everythinhg i could but couldnt recover recovery. but this helped a lot .
Just a question can i mount usb storage on grand 2 . because i can see usb storageA….and many more in \mnt folder. Thank you again.
Hi, while exiting it asks whether you want to get back to previous recovery.
And Grand 2 doesn’t support USB storage. It has been even tested with custom kernel by xda guys still no luck
