You can download your latest firmware from www.sammobile.com. And flash using Odin without tripping the knox.
Root will trigger the knox flag to 0x1, that's the basic until now but im unsure of i9505. As im i9500 user.
Ive seen quite a lot of dev's doing an analysis on how the knox behavior.
Visit XDA's forum

as ex-S4 4G , i9505 owners said, once u root w CF-auto root, your knox counter will triggered forever...
since Knox BL is started from 4.3 MK5 firmware till NDNB firmwares [imo]
well, just root it n dun fear about it as well

anyway, own opinions


this s4 is still in warranty,
my concern is to have another kernel so that i can control n limit voltage so that it consume low power and yield minimize temp..
but root will knox counter, im thinking twice to do or not to do..
my s2 is super easy then this s4 matter
