[Q] Galaxy S4 I337 (UCUEMK2) Factory Firmware topic

OK.... So I know I have seen this question posted before, but all of the posts I can find are dated old and I'm hoping that firmware has been released. Is there anyway to get factory firmware for UCUEMK2 in Odin? Had I known there was no factory firmware, I would have never rooted. lol. Please help if possible.

Thank you!
