When rooting your Galaxy Note 3 by installing a custom CWM/TWRP recovery, you may flag the Knox counter.
What is Knox counter?
Previously, Samsung used binary counters on Galaxy Note 2 and earlier devices. Starting with Note 3, Samsung is using Knox counter, which is basically the “new” binary counter.
Now, this doesn’t exist on all Galaxy Note 3s, but only some of them. So, if you have a Knox counter, you will see something like:
Knox Warranty Void: 0x0
Knox Warranty Void: 0x1
0x0 may be the default and 0x1 is if you install a custom CWM/TWRP recovery.
Will this void your warranty?
If you do have Knox counter, yes but there are developers who are already working on this so you can revert back similar to what Triangle Away app did with binary counters.
So what should I do?
If you are not going to be returning your Note 3 anytime soon, I wouldn’t worry too much about it as there should be a method to get around it in the next 1-3 months (we are not sure how long it’s going to take). But if you are returning your Note 3 for warranty directly to Samsung, you might want to think twice before rooting.
