Default [Q] Flashing a Verizon S4 to Cricket?

I have looked at several different methods of doing this (what I thought would be a simple) task. I have the phone rooted. I have tried CWM, using ODIN, Loki, a few other things that have lead me in different directions.

I guess in short the question is, how do I get this Verizon S4 flashed to Cricket? I out right own the phone, the "Root Checker" app says that I have root access. I would prefer to do it from a Terminal on the phone but whatever method actually works would be great. Thanks in advance.
