I rooted with a new universal rooter tool that does disable Knox before rooting. Easy peasy and safe to boot! Look up saferoot.zip

I use root cloak and root cloak donate. Kies detects no issues with safe root installed, as it disables Knox.
I will wait on any 4.4 load, as there always will be bugs with developed apps in Xposed. Gosh, I am still waiting for 4.2 bug fixes on some Xposed apps. I rather have a fully working device than a half baked device you can get from any vendor. I get so irritated at official released updates that break things, let alone get a new device out of the box to find out it was not fully tested. I guess Microsoft has made peeps give in to poorly developed function. Just reboot,or patch and you will be fine.

( A poor excuse for releasing something too soon. Just look at Xbox and other game consoles being push out in a rush to gain sales. Bah!!!!
