How to Install TWRP Recovery Without Tripping Knox on your Samsung Galaxy device

   Update: It may NOT work. As per the feedback from a few users in the comments section below, it seems this trick doesn’t works as it’s supposed to. We’d advice you to NOT trust this trick anymore.

The best known and most safe way to root your Samsung Android device is Cf-Auto-Root tool by the renowned developer Chainfire. But, unfortunately, CFAR also trips the KNOX counter on your Samsung device, which disables Knox and tells the Samsung reps that you’ve tinkered with the system files on the device and hence voids warranty. So what is a Knox safe way? 

Well, there are a few much simpler ways to achieve root on your Samsung Android device like the “Kingo Root” and “CC Root”. However, these methods are known to be unsafe to use for various reasons. But if you decide to use them anyway, you save yourself from tripping the Knox counter on your device and hence keep warranty even after rooting.

But what if you want to flash a custom recovery as well? If you flash the recovery with Odin, you’ll trip the Knox counter. But if your device is already rooted, you can use an app called Flashify to directly flash .img recovery files from your device itself without the need of a PC, which would also save you from tripping the Knox counter.

Let’s see how to do this.

  1. Download the TWRP recovery .img file for your Samsung device. Go to twrp.me/devices, look for your device and download the latest .img file from there to your device.
  2. Download and install Flashify App from Play Store (link →).
  3. Open Flashify and grant it root access when it asks.
  4. Now select the “Recovery image” option under flashing options and select the TWRP recovery’s .img file that you downloaded on your device.
  5. Press Yup! to confirm flashing.
  6. Once flashing process finishes, the app will ask if you want to reboot, just hit the back button to ignore the prompt.

Reboot into recovery mode

Now that recovery is installed on your device, here’s how you can boot into recovery mode:

  1. Switch Off your device.
  2. Hold “Volume Up + Power + Home” button together and release them as soon as you the device logo on screen. You’ll boot into recovery mode.

Enjoy!

  5. Yeah it tripped my knox counter too and I also followed the instructions to the letter.

    1. It actually trips KNOX cause you modified or for mich simpler flash a unsigned image of recovery, no matter what method you use, even it is from the phone, the KNOX is in the phone anyway.

  7. Problem is: Flashify ask ROOT>> your device has been ROOT already>> Knox tripped already

  8. Hi Shivam:

    “But if your device is already rooted, you can use an app called Flashify to directly flash .img recovery files from your device itself without the need of a PC, which would also save you from tripping the Knox counter”

    This is what I was hoping too but apparently it’s not totally correct. The flashing itself via Flashify (or Flashfire) wouldn’t be the thing which causes KNOX to trip, but rather a custom kernel is the cause. Something which most custom roms have.
