Besides, this tutorial is also to root your android smartphone for you who have installed CWM custom recovery via PC / Computer.
What we need :
* Already installed CWM custom recovery. If you have not, then you can read How to Install CWM recovery without PC / Computer.
* A zip file of CWM-Supersu v 1.9.4.zip
Steps install Supersu [Chainfire] via CWM
1. For you who had installed another supersu app like 360 Super Root, Root Dashi / King Root, and etc, you must delete the apps first.
2. Download file CWM-Supersu v 1.9.4.zip, place it in external sdcard.
3. Go to recovery mode. Turn off your android smartphone, then simultaneously press and hold the volume up+power+home button for about 5 second.
4. Now you are in recovery mode, choose "Install zip" --> "install zip from sdcard" --> find where you save the CWM-supersu zip file and choose it --> "...yes..." --> Go back and reboot your Android smartphone.
After the installation success, we can update the supersu and the binary by downloading Supersu [Chainfire] at the app market. When we open the updated Chainfire Supersu for the first time as it ask to update the binary, we can choose with "..CWM/TWRP..." (but via "Normal" too sometimes work for me). Then if we update the root binary of our Android smartphone, it will be more suitable for every new update of root-needed applications.
