The SU binary must be updated Xiaomi redmi 2 runs MIUI 6.2.4.0(KHJCNBK)

I ran a zip file in CWM, and had a success done!:



Then installed SuperSU from google play, it wanted to update binary, so I clicked normal. It said failed and wanted me to reboot. I did, tried the second option (CWM). It says SuperSu will attempt to reboot. I click ok and nothing happens. What's the way out?
Reboot into recovery after copying this file into root of your SD card. Flash this file using a custom recovery like CWM . Reboot phone. Check for SuperSu in your app drawer.

SuperSu 2.46
