Some Important Things

Show File Extensions - Open a command prompt window and run "Control folders" (without the quotes). Go to the View tab and uncheck the "Hide extensions for known file types" option. This will help avoid confusion when renaming files.
Battery - Ensure that your phone has at least 60% battery remaining and that your PC is plugged in and won't shut down spontaneously during the process. The procedure doesn't take very long , but it's best to have enough charge in case something goes wrong.
Backup (Optional) - Unlocking the bootloader will/should completely wipe all data from the device. This includes apps, settings and even the contents of the internal sd card (pictures, music, etc.). Copy all important files off the phone onto a PC or upload them to a cloud.

Downloads
Download a custom recovery and the SuperSU zip below. Place both files on the desktop.

TWRP:

Root:
  • USB Debugging - On your phone go to Settings > About phone > Tap on Build number 7 times. This will enable Developer options. Now go back to Settings > Developer options > Enable USB debugging
  • Enable OEM Unlocking - On your phone go to Settings > Developer options. Then enable the 'OEM Unlocking' option. Also,a free advice, make sure that from now on,OEM unlocking option is enabled before you reboot. Sometimes,it might get disabled itself.
  • Enable Advanced Reboot - On your phone go to Settings > Developer options. Then enable the 'Advanced Reboot' option.
Unlocking Bootloader

  • Turn the phone off. Then boot it into fastboot mode by holding volume up + power. The phone will display "fastboot" text indicating that it has successfully entered fastboot mode.
  • Plug the phone into your PC, then open a command prompt window on the desktop (Shift + Right Click -> Open Command Window here) and type :-
  • Code: fastboot devices
  • This command will list the connected devices. If your phone's serial number shows up you are good to go and may continue. If the phone is NOT listed this indicates that your drivers are not installed correctly. In order for you to continue you must fix your drivers so that your phone is listed under fastboot devices.
  • If the phone has been recognised by the command above, proceed to unlock the bootloader with the following command: Remember that this step will/should wipe EVERYTHING off the phone
  • Code: fastboot oem unlock
  • After the above command has finished executing, run the following
  • Code: fastboot reboot
  • Now, your phone will reboot. Continue to the next step to install Custom Recovery
