What is Binary Counter/Knox Counter for Galaxy Note 3?

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.

    I wish I had seen the Knox info earlier before I ran the root. I wanted to have Knox available. Might be good to mention this in the beginning of the root post. I’m not sure there will be a fix for the void, it triggers a efuse which is hardware related. No fix, must be replaced. Don’t root if you want Knox, or search XDA for the new root method that preserves Knox.

    Extract the superuser apk out of the zip. Side load it as an app. You will need to fully remove superuser that you already have installed first.

  6. TechyMarkbo says:

    As far as I know, there can’t be a fix. It is hardware tripped.

    Hi all!
    As far as I know, Knox is installed on both Note 3 variants, n9005 (snapdragon) and n900 (exynos). That means when you root or load an cooked rom into your device, the Knox counter starts to count and you get 0x1 on the Knox Warranty Void. But only on the n9005 variant, Samsung sets a chip which is called “eFuse” in it. This one is affected by Knox and supposed to damage your device’s HARDWARE. That’s a serious risk and a big difference between these two variants, n9005 – n900.
    Is there anyone who concerns and does researches on this issue?

    You should do a piece about KNOX being installed on the GalaxyS3 via OTA update.
