rooting Kitkat devices topic

Hai guys, am new to this stuff but am always eager to help and get help from others.

I happen to be a kikat user and the thing is that there haven't been much methods or ways on how to root these devices. I have tried all the popular rooting applications like framaroot, towelroot, vroot or iroot..........for mobile and iroot, kingoroot and some other Chinese rooting application...... But failed

My device is xperia e3 running android 4.4.2
My humble request is to the developers to try and develop an application for rooting my device or of the same type...... Without major complications.... And as soon as possible

Thanks in advance :)
