Hello Everyone!!!!
This is a rooting guide for ZTE Grand SII (S251) which was released in india in the past week.... after trying a number of tools i was successfully able to root the phone, so this is a guide for those who would like to root their phone.... i am not a developer just a power user
1) Connect ur phone to ur pc first time in "Install driver mode" and install the adb drivers first... (Or else you can run setup from the attached file below for installing the drivers for your phone)
2) Once drivers are installed enable "developers Option" in settings and enable "USB debugging"
3) Then download root genius from the attachment below
4) Connect your phone to the pc and select "connect to pc Software" and let the drivers install
5) fire up root genius with administers privileges (you should have internet connection for this)
6) if you have done everything as described above then u should see connected on bottom left of your screen, click i accept agreement and click root and wait....
7) It should take 2 to 3 mins to root using all the possible exploits (internet connection is required for this) and then it should say that you have successfully rooted your phone
8) Once it tells you its successfully rooted close the program disconnect your phone from pc and restart
9) you should see a new program called KingUser in your app drawer (which is like superUser)
10) and Voila!!! your phone is rooted!!!! to confirm this download any free root checker from playstore and check your root privileges.....
NB:
1) You can replace kinguser with super user just by downloading it from the store and installing and updating its binary...... i have taken a backup of kinguser in titanium backup before installing superuser and replacing it as a system app.....
2) You can follow this guide cautiously cause if you brick your phone then i am not responsible..... this has worked for me and hence wanted to share it with the community which has helped me countless times in the past.....
3) if you root your phone your warranty would also void and i am not responsible for the same.....
4) any help or suggestion would definitely help with that

Thx bro... Just trying to help.... Nope a developer needs to port the ROM for our device then only we might get a custom ROM...
The Antutu score is 39554 on v5.1

Guys can you confirm the model number is S251 for the Indian version of ZTE Grand S2. Also did anyone come across stock official firmware for ZTE Grand S2? I was a kernel developer for Xperia ZL previously and I can try porting recovery for our device if anyone could point me to any stock firmware for this device so that I can recover my device incase I brick it.

Yep the Indian Grand s2 model number is S251 and it's only 3g with CDMA unlike the international variant which is 4g lte variant ..... And i have yet to come across a stock firmware and recovery for this device hence am skeptical to flash anything else... Wish u could help us out with a working custom recovery....

I've already received my device and started working on CWM. I was thinking of making a unification thread for all the ZTE Grand S II devices. I'll try doing that but if anyone's willing to do that post the link to that thread here to redirect users. Also I found the stock firmware files for our device so we can always go back to working stock firmware in case anything goes wrong. I'll post link to stock firmware later

Wow... Would really appreciate that.... Just be sure which thread u would be merging because the international variant is completely different (snapdragon 801 whereas ours is 800) would really luv to see the links to stock firmware and recovery...

There are some ROMs present on the below link which state the model as ZTE-S251, the one we have in India. But how to check if these will work on our phones.

Hello, and welcome to XDA! The best place to ask would be the dedicated SuperSu thread: http://forum.xda-developers.com/showthread.php?t=1538053. You will need to register to post, and to give more details as to what exactly happens when it fails.
Good luck!

Hmm ... you already found the right CM ROM thread: [ROM][UNOFFICIAL] CM 12.1 for Galaxy Grand Duos (I9082/I9082L) (Update 20151010) 2SIM by pawitp.
If you have further questions or need additional help, you should ask in the corresponding Q&A thread.
There you might get best help and advices.
Signature error on flashing can be caused by different things, e.g. corrupt download, ROM zip file is for another device, etc.
So try to re-download the file(s) on a different computer and check MD5 checksum (if available) to be sure that it's not a bad download.
If it does not help, you can post your question in the [Help Thread][GT-I9082/L] Ask Any Question , Noob Friendly by Yousef Mohamed.
Good luck !

Hi
Thank you for using xda assist.
May I know where you got the rom?
You can go back there and you can ask the developer about the problem you are having.
I cant find a dedicated thread for the device here at XDA
But you can also post this here
http://forum.xda-developers.com/android/help
Thank you.
