 ( Caution : Rooting Will Ultimately Void Warranty and do not Continue if you don't have Done it before or not know the Basics )



1.Grab the insecure boot image by Harry GT-S5830 from this thread 

2.Also download these root files. This package includes the latest SuperSU 0.98 (all credits to Chainfire), latest su binary that comes with it, and working busybox (not sure if latest).

3.Extract the contents of the downloaded zip file to your computer.

4.Enable Android Debugging from Settings > Developer Options. (If you can't find developer options, go to 'About' and tap 'Build number' seven times.)

5.Connect the device to your computer via USB, and install the required drivers (Thanks Stryder5).

6.Reboot into fastboot/bootloader:
Code:
adb reboot bootloaderYou can also power off the phone and then use power + volume-down key combination to get into bootloader.

7.Unlock the bootloader if you haven't done so already:

Code:
fastboot oem unlock

8.Get back into bootloader mode and boot into the downloaded insecure boot image:

Code:
fastboot boot boot.imgDon't worry, this will not replace your existing boot image and will only boot from the insecure one once.

9.Once booted into Android successfully using the insecure boot image, simply enter these commands one by one in command prompt (making sure you are in the directory where you downloaded the files):

Code:
adb shell mount -o remount,rw /system

adb push su /system/bin/

adb push Superuser.apk /system/app/

adb push busybox /system/xbin/

adb shell

chmod 06755 /system/bin/su

chmod 0644 /system/app/Superuser.apk

chmod 04755 /system/xbin/busybox

cd /system/xbin

busybox --install /system/xbin/

exit

exitYou will now have root access. Tested and confirmed working by Stryder5 and many others.
