ALL THE APPLICATIONS/SOFTWARES WHICH YOU WILL BE RUNNING ON WINDOWS PLATFORM, WHILE LAUNCHING SETUP USING EXE FILE OR STARTING SOFTWARE AFTER INSTALLATION BY DOUBLE CLICKING SHORTCUT, DO IT BY RIGHT CLICKING ON IT & CLICK "RUN AS ADMINISTRATOR" EVERY TIME. Works on windows 7 x64 as tested by me

these are the exact steps which i followed, if you think some of them are un-necessarily added, then you can skip them (for advance pro users)

STEP 1:

Download following archived files & extract them & keep those extraxted folders on desktop for easy access.

STEP 3:

CONNECT PHONE

Make sure phone is prepared for connection as per first note above

serach online for drivers (it will take long time...be patient)

all drivers will get installed

make sure there's atleast a driver installed for each of the hardware....there must not be any device left with no driver at all....triangular yellow mark isnt an issue but just make sure that some driver is installed for each device.

when online search gives up, you will need to click install/update driver manually by pointing to those extracted folders above (i.e. on your Desktop)

you may need to restart system quite a few times during each of the driver installation

DISCONNECT PHONE AT THE END

STEP 4:

Install moborobo PC suite....run setup as administrator

download from here

.

http://www.moborobo.com/products/moborobo.html

.

open it as administrator

CONNECT PHONE....let it install drivers & recognize your phone as "Sprd-B51"

after you make sure that all drivers are installed, disconnect the phone from PC, exit/KILL PC suite completely (from notification area as well)

exit PC suite from phone status bar...stop/KILL PC suite apps in phone & uninstall them.

STEP 5:

download & install (run setup as administrator) Root Master (latest version VRoot_1.7.5.5379_Setup.exe)

Keep SuperSU installed in ur device. download it from play store. dont open it now.

connect phone to PC

Open root master by running it as administrator (else it wont succeed)

.

.

Click button highlighted in red rectangle in pic above (skip this step if device gets recognized automatically as soon as you open root master as happened with me....recognized as "Sprd-B51")

.

.

Follow and click button highlighted in red rectangle-which i am showing in above picture ! your device is now connected to this software & ready to be rooted

Click on root and wait !

.

.

it will automatically reboot your device as shown in pic below after root is successful

.

.

You can see this Chinese superuser in your menu! (icon may differ but in while & light blue color combination only)

.

.

open SuperSU grant permisson like this

.

.

supersu will automatically install su binary (need internet connection)! just grant the permisson and let the supersu uninstall Chinese superuser

.

.

Your device is now rooted

THIS POST IS COMBINATION OF ALL THE THREADS ABOVE

FOLLOWED THOSE MICROMAX THREADS BECAUSE THOSE DEVICES USES SAME CHIPSET (i.e. SP6820)

PS: you can refer threads above for references. I didnt rooted my device to install custom ROMs, so dont ask me regarding the same, I'm noob in dat case :D

I rooted to uninstall some of the pre-installed apps to get a bit more free internal memory & to get screenshot feature...That's it :)
