-after installing just click on "root" when you are online (kingo root only works online)
-but what you should have done is to download and install kingo root software (free in google) on your computer and connect phone to comp and after enabling USB DEBUGGING kwa phone, it will automatically root your phone. (connect to net also)
FOR OFFLINE if you dont have net, download iroot software (also free in google), install in your comp, connect phone to comp, enable USB DEBUGGING in phone and after cliking root, your phone will automatically root. the downside or iroot is that it will root in chinese language while you're offlie. To root in english, connect to internet. Haitakawia sana. just around 8-10 minutes the rooting will be done.
