It's tangential but I want to point out to those who doesn't follow the rooting community closely that Samsung doesn't lock the bootloaders of phones unless it's requested by the carrier. International editions, Play store editions, and contract phones from carriers which doesn't request locking are unlocked by default. You can install whatever you want on it. Even if it has Knox. Knox doesn't mean locked bootloader, its relation to rooting is that it voids the warranty when it detects rooting, it doesn't lock the bootloader or prevent rooting. Corollary: I'm aware of the fact that it is not always possible, but buy your phones off contract when possible. Life is too short for fiddling with those nonsense, and also vote with your wallet.
