Moving from CM11 to an other rom
I wanted to get rid of my stock rom and I didn't have much time to read much about it so I just used the CM installer which got me to 4.4.2 (I wanted CM10.2 and I thought I would have a chance to choose the desired version but I realised it just goes to the most recent one). I am not happy with the battery though and I would like to change rom and probably go to CM 10.2. The thing is I am pretty new to android and I havent even rooted a phone before. So I was wondering which are the steps from here to change a rom so I can read the relevant guides this time.
