Today I was looking to some beautiful CM11 themes but I found out that in order to install them you have to first of all root your device and then do a bunch of other things. The thing is that I have never rooted a phone before, so I could really use some help. If anyone was willing to explain me in simple words without technical terms how to root the phone and then help me with the custom ROM thing. any help would be very much appreciated. I'm using LG Magna.
