software issue

[sfilansno1fan]

hi i was having issues with my s4 recently and was advised to reset the software using kies 3 however when i tried this kies tells me that my galaxy s4 does not support initialising my phone has not been touched in anyway since i got in back in august with virgin media ive only ever done software updates through kies when they were there
does anyone know what that means ?
i have tried searching the internet but cannot find a straight answer

Maybe this is a Knox bootloader issue? Other than that I am not sure. This is the first I have heard of.

Doesn't sound rooted to me. Why can't you just do a factory restore right from the phones settings itself?
Instead of using Kies
