>Before rooting the phone unmount the SD-Card/External Storage.
>Un-check the "allow mock location" under Developers Option(where USB Debugging is located)
>Proper installation of ADB drivers and required drivers. Google PDAnet application to get proper drivers without hassles ^_^
>Download >> androidxda . com/data/RootGenius . exe << latest version for English site, CH site(original) >> www . sjroot . com <<.
install the downloaded software and drivers on your computer (I used my old Windows XP SP2 PC)!!
*Root Genius (doesn't really required installation)
*ADB drivers or the PDAnet application
run or open the Root Genius app.
*it will ask to connect your phone with "USB Debugging mode" enabled or checked via Settings > Developer Option.
connect your phone and wait for app to detect your phone and then just click on the "Next" button on the bottom right corner of the app.
watch your phone carefully and wait for the "green" progress bar to fill up, usually on 27% you will notice on your phone that Root Genius is working/doing the rooting it will flash at least twice.
when you see the "Congratulation your phone is successfully rooted!" on your computer screen that's it!
*disconnect your phone from PC and reboot the phone.
*look for the Kinguser app on your phone.
*use Root checker app found on the playstore.
*use any app that requires root access.
That's all folks, hope I helped =))
