About Samsung’s Knox Counter

Some OEMs have decided to implement their own security software in their devices, most of the time this comes in the form of Bloatware, or software, in this case, Samsung’s Knox counter security feature is implemented deeper in the Device’s Memory/Operating system. This is an introduction to the Knox Counter.

Knox is a very annoying and troublesome feature to most Samsung users who like to tamper/make heavy customizations to their device. “Tripping” the Knox counter will VOID your warranty, thus rendering your device useless to Samsung’s warranty center. The Knox counter shows informative and detailed information to Samsung’s employees. They use their systems to detect whether or not your device has been tampered with, past Samsung’s warranty.

If you for some reason want to claim warranty for your device, but haven’t done anything major to it like Root your device, or Flash Roms, then you should be fine in the warranty area. If you have however, this can be troublesome for you, as 99% of the time; Samsung’s warranty center will reject your warranty claim.  When rooting your Samsung device with Odin and install SuperSU Root permissions app, you may be shown a notification Prompt when in the SuperSU app to Disable KNOX, this step is necessary for SuperSU to function properly.

Knox may sound like a very useless and annoying feature, but it has some security perks to it as well. Those of which include the following:

  • If you somehow manage to lose your device, the device cannot be used unless the person has access to your Samsung account, on top of that, they cannot make firmware changes, like flashing a custom Rom or recovery, and cannot factory reset the device.
  • KNOX uses its technology to secure your data and apps from unwanted hands

Keep in mind when you attempt to install/flash a custom Recovery/Firmware/Rom, the instant the Knox counter gets tripped, the advantages Knox provides you with will immediately be deactivated. The easiest way to check or confirm whether or not your KNOX counter has been tripped is, enter “Download Mode.” Entering Download mode is different for some devices, for certain devices, you must hold the Power button + Home Button + Volume up and Down, at the same time. Usually the method for entering Download mode for most Samsung devices are as follows:

  • Power off your device
  • Hold Power Button + Home Button + Volume Down Button
  • You should see Warning!! Text on your screen.
  • At the top right hand side corner, you should see some text, you can recognize Knox as Knox Warranty Void: 0x0 (Which indicates your warranty is not void, and 0x1 for void warranty)


There aren’t many stable ways of resetting the counter back to 0x0. One way however, is by using the app Triangle Away, by Chainfire, who also developed the app SuperSU.

How to reset knox warranty code

This app costs $2.49 on the Google Play store, and is unstable. This app requires Root Permissions to function, and is only supported on select Samsung Devices. The app’s purpose is to force reset the flash counter, or Knox counter, back to 0, so Samsung cannot detect any custom firmwares have been flashed or device modifications have taken place.

The supported device for Triangle Away will be listed below. (Supported list of devices sourced from Triangle Away Google Play Store app description)

  • Samsung Galaxy S2 (GT-19100)
  • -Sprint Epic 4G Touch Variant
  • -Korean Model: SHW-M250K/L/S
  • Samsung Galaxy S3 (GT-19300/19300T/GT-19305/19305T/19305N LTE)
  • -Korean Model: SHV-E210K/L/S, SHW-M440S
  • Samsung Galaxy S4 (GT-19505
  • Samsung Galaxy Note (GT-N7000/GT-19220_
  • Samsung Galaxy Note 2 (GT-N7100/N7100T/N7102/N7105/N7105T)
  • -Canadian Models: 1317M/T889V
  • -Korean Models: SHV-E205K/L/S
  • Samsung Galaxy Note 3 (Android 4.4+/ GT-N9005)

That long list might look like a heck lot of supported devices, but mostly out dated/obsolete/nobody uses kind of devices. Most of the time newer models will not support Triangle Away. If you’ve tripped your Knox counter and voided your warranty, chances are your warranty availability duration is pretty much done. The only thing you can do is wait for new solutions for reverting/resetting the counter.

If you value the warranty you receive when purchasing a Samsung device, be patient and wait until your warranty is no longer available, then go nuts and flash whatever you want. Be aware, that when using Odin to flash KNOX Enabled firmwares on your device, the Knox counter will still be tripped to 0x1.

Maybe you can absorb some knowledge from this article. If you’re an avid Root user/Flash Fnatic who happens to also use Samsung’s devices,  you might already know what Knox is and what it does, but you should also keep in mind your warranty will thank you if you don’t trip Knox.

  1. Sorry, but the Not GT-N7000 doesn’t have KNOX !!!.
    My Tab S2 (T-13 has and when starting, there’s a yellow message saying: warranty is void.

    Well, so be it. ot rooting is NO option !!!.

  2. Triangle away support smj200g

  3. Will it reset anything if we goto download mode,can’t we come back safe?

  4. Abraham Nunez says:

    Will it work for the note 4 on t-mobile?

  5. What is the meaning of “KNOX Enabled Firmwares”?

    • ROM that run a custom knox switch
      Usually, rooted firmware will run knox, however they need to be modified in order to be flashed
      This will guarantee the knox switch being tripped.

  6. Jamilah Shariff says:

    My Galaxy Note 3 has been installed by someone using copy right version by Eric Leong. Now I have 2 Knox the original by Samsung I could not activate because like being blocked. Kindly assist me.
    Thank you in anticipation.

  7. the best bet is just to not buy a samsung phone – I tripped my Knox on a previous phone and they refused to honour the warranty when the phone developed screen lamination problems. My current phone is a one plus X – they don’t load their phones with bloatware so there has been no need to install a custom rom yet (am just using a nexus overlay). If you believe that you should own the device you buy, then tell Samsung they can go spin on it.

  8. This article is useless without a date.

    How about the other effects of Knox? Does it prevent you from getting official Android updates from Samsung?

    • The article is worse than useless, with or without a date, because the majority of it is wrong. I very strongly suggest that if you are considering making any changes to a Knox enabled device, you spend some time looking at relevant posts on xda forums. Unfortunately, not everything that has been written there is true either, but if you read enough, you’ll get the hang of what’s true and what isn’t.

  9. So you are telling me that if I try to flash on my Note 4 (bought and locked in Orange Romania) the official Germany 5.0.1 firmware through Odin, my warranty will be over?
