Type : adb reboot-bootloader
Your phone will restart into bootloader. 

Type : fastboot -i 0x1ebf oem device-info
If your bootloader is unlocked, it will say "True", else it will say "false". If it is False, then do the next step

WARNING : All your userdata will be GONE! Now you can root your phone in two ways

Method 1 : If you want to retain the Original Recovery - Hot boot

Type : fastboot -i 0x1ebf boot TWRP_V2.8.7.0_YUREKA.img

This will launch TWRP on your device. Navigate to where you saved the UPDATE-SuperSU-v2.46.zip file. Flash it, wipe Cache, Reboot and you are rooted!

Method 2: If you want to flash Custom Recovery - Flash

Type : fastboot -i 0x1ebf flash recovery TWRP_V2.8.7.0_YUREKA.img

Your Cyanogen recovery will be replaced with TWRP. Then, unplug your device, hold volume up+down+power to boot into recovery, navigate to where you saved the UPDATE-SuperSU-v2.46.zip file. Flash it, wipe Cache, Reboot and you are rooted!

Note: For those stuck in a bootloop! After flashing TWRP, go to Wipe and hit Format Data...then reboot to recovery (everything will be mounted by now) and flash the chainfire SU binaries. Reboot and everything should work fine. The phone may be stuck in the "Cyanogen" screen for a goot 5-10 mins before the apps start loading...so stay patient.
