I'm trying to find a way to root my phone so I can delete these factory installed apps, make my phone faster etc.
Can someone tell step by step on how to achieve this? Do I need to download something? Etc
By rooting your device you will lose your warranty and during this process you may brick the device. You are doing it at your risk.
Do I need to download something?
Another tutorial can be found here and includes pictures of the process too.
