The other thing is, I want to have a go at flashing custom ROMs to my device. My warranty runs out next month so this would be perfect, providing the above question is true (that it doesn't disable full functionality) I will go and follow normal tutorials.
Now I've been reading about SafeStrap and how it creates the ability to flash ROMs without touching vital system parts that would trip KNOX. Is this true? Could I really root without tripping, install SafeStrap and finally install custom ROMs without tripping KNOX or am I in a dream world haha?
