Repost: Return to Stock ROM

This question was originally posted here but didn't seem to get much traction. Hoping putting it on its own thread will help me get the answers I'm looking for.

I recently un-rooted my Moto X 2014 to take an OTA update and then re-rooted it again. (Ref: http://forum.xda-developers.com/moto...phone-t3179350). I was really surprised by how smoothly everything went, and it got me thinking that I'd kind of like to update my old Nexus 4 that I keep around to use as a WiFi only device for music and such. I downloaded the factory image (Ref: https://developers.google.com/androi...s/images?hl=en), so my question is: will the process be as simple? Do I just boot into fastboot and flash system.img? As in the first post I linked, I don't want to lose any of my data or settings, nor do I want to lose root. Current Status: Android version: 4.2.2 Kernel version: 3.4.0-perf...CyanogenMod CyanogenMod version: 10.1.3-mako What I'd like to do is get my phone back as close to stock as possible (from a UX perspective, probably want to keep custom recovery), while maintaining root and without losing any data or settings. Any references for the best way to go about this? Thanks in advance!
