Flash PP Verizon S4 back to fully stock help please topic

PP now supports the S4 and I would like to return the phone back to Verizon original condition. I have a stock rom and I believe with a stock Odin will work without tripping Knox, but how to I flash the lower information that I used Odin to get it on PP to begin with that doesn't change with a rom flash. The person also said that the 4G information is missing and that needs to be re-installed. There probably is a post here, but I have had no luck in finding it.

Thanks,
Mark
