Complicated?
1. Use simple tool to flash a provided kernel.
2. Root by double clicking a batch file.
3. Use simple tool to flash original kernel.
Honestly, if you cannot follow simple step-by-step instructions then you shouldn't be rooting your phone in the first place.
As for questioning DooMLoRD's ability because he hasn't created a one-click solution; why should he spend his free time doing so? Firstly, the method he provided already works just fine and secondly, this is a development based site, not a place to hold people's hands.
