Root [Sprint] How do you save a rom once rooted for installing via recocery


Android Expert
Not sure if this is an easy process but basically I an working on a project to create a rom and need some help from the seasoned people that have done this.
It will be a simple rom based off the ng5 and more or less like themed I guess you'd say, to the launcher, settings, etc. on the s4.

What I need to do first is install ng5 firmware (since I can't find a rooted ng5 l720t rom) and I'll root that then save it as a rooted rom to flash via a recovery. This will give me a base rom to work with.

So what I want to know is once I root ng5, how do you save that as a rom file for later use?
