[Q] Root and Knox on i9506 ks01lte topic

I just got a brand new i9506 ks01lte today and previously I was playing with a pre-knox 9505 from work but I'm not sure what knox is about and which root method I should use.

The phone has 4.4.2 out of the box but I'm not going to use it unless I am running CM11, CM12 or similar.

There was a rooting guide which mentioned kit kat in the title but the thread was closed so I couldn't ask if the information in the first post was still relevant to my phone.

I don't care about voiding warranty obviously, just unsure about what kind of difference knox makes and if there is a procedure that will work on my 4.4.2 9506.

The one thing I don't want to do is brick the phone.

Thanks

Vic
