Hello, I'm wondering if there is a root that doesn't require a pc or Odin access for the Galaxy S7 active (g891a)? I'm not looking for a permanent root, something like KingRoot, that when the device is powered off the root turns off too. I've seen several things searching Google but I keep coming up with the same thing, everything that promises no pc access doesn't work. I'm not a veteran with this but not quite a novice either. Any ideas?
