Verizon Galaxy S4 Kit Kat and Rollback

[AC Question]

I have read a lot of issues with the Galaxy S4 and Kit KAt 4.4.2. In particular I am having problems with Bluetoorh and Texting. Has anyone had success in rollback to Jelly Bean? If so can you point me to instructions?

Biggest problem here is KNOX security. I'm sure there is a way to do it but doing it successfully and without hard bricking the device is the risk factor. Since the introduction of KNOX it has made rooting and flashing Samsung devices a real pita.
