Hello!
Thanks for your initiative and advice.
I want to offer you an alternative, namely Kingoroot, one of the pest one-click-root.
This is an app that lets you root your Android with just a tap in a matter of seconds, and without having to do any particularly complex or dangerous procedures.
It works on dozens of different device models that use any version of Android between 1.5 and 5.0. And all of them use the same process for rooting the device: hit the ROOT button. Of course, if your device is already rooted, the app will tell you so. You can also unroot a device in the same way that you root it, all in a matter of seconds.
During app's installation, a pop-up window may appear saying that installing Kingo ROOT is dangerous. This is because rooting a device always implies certain risks. In any case, you just have to hit 'Install Anyway (unsafe)' to proceed.
