I have a Galaxy SCH-I535 from verizon (SGS3). It is not rooted, and I want to install CM 11 on it.
Is there anything else I have to do besides just running the installer?
I love my phone and don't want to break it. Do I have to root or install anything else before running the CM11 installer app? And, what should I use to back it up before hand in case anything goes wrong?
Could someone tell me what I should do step-by-step before actually running the CM 11 installer?
