Quick beginner question here:
I know this is the Nexus 7 forum, but since it should work exactly the same with my Nexus 4, I'm asking in this thread. I'm trying to backup my Nexus 4 and then install Cyanogenmod. I am a complete beginner to all this, and I have never had anything other than Stock Android on my phone - it is 100% stock and has never been rooted or anything. So I really have no clue about it.
I have googled a bit, and it's confusing, because most articles about this phone are 2-3 years old and I'm not sure how it is nowadays. I've seen somewhere, that I need to create a backup of my stock phone (Android 5.1.1), before I attempt to do anything. However, if I click "Create Nandroid Backup w/ Custom Recovery" on Nexus Root Toolkit, it says my device needs to be "unlocked", but if I want to unlock it using this Toolkit, it says, unlocking will wipe my data. So I'm completely confused about what to do now.
Is there maybe a current guide (at least for Lollipop) for Nexus devices, that explains EVERYTHING from backup to flashing the ROM, step by step, for someone who's never done this before? Or could someone help me out here? Thanks a lot!
