Cannot root phone by installing superuser.zip CWM v6.0.5.1 Stable Xiaomi redmi 2 runs MIUI 6.2.4.0(KHJCNBK)

In order to install CWM, I downloaded both the adb and fastboot, I extracted recovery.img in the folder, together with them. I entered fastboot mode.

Then, in fastboot I ran:

fastboot flash recovery recovery.img

fastboot reboot


Now I booted CWM into recovery. It I ran this superuser file, which matches my phone model. It installed, had done! at the end:


 However, when I exit the menu it asks me whether to root the phone ( with root access is missing at the top ), I tried both yes/no, it reboots, but phone is still not rooted. What's the issue here?
You did succesfully installed the superuser framework but you need to install SuperSu what controls everything. Follow steps below to successfully install SuperSu:

Download SuperSu from the play store here.
Open SuperSu and you should see something like this:

Click continue.
Click normal. (If you see message for more then 5 minutes then reboot and try the other option)
Reboot your phone and now you should be rooted. Check it with a root checker app like this:

Consider purchasing the pro version to support the developer here.
