you have philz recovery not stock recovery? but you're on 4.4.2 rooted and everything?
I'd boot into download mode and see if you have knox void within the download mode. also, look at setting and see if you can tell which bootloader you're on.
No knox, philz, rooted and 4.4.2 . For anyone googling secret I emailed mobiletech and he said I was unlocked. Just put me on 4.4.2 I guess instead of 4.1.2.
It's fine but I was scared. I haven't flashed anything yet waiting till Monday I'm really busy right now. I believes the download screen just said stock samsumg official.
Weird there isn't a way to tell since flashing can brick your phone
