Root Galaxy Note 2 on Android 4.3 firmware, also removes KNOX

Note 2 GT-N7100

Traditional rooting tools would result in breaking the warranty of your Note 2 device, so, whether you already knew it or not, you need a fill-proof (or KNOX-proof) root tool, which would help you turn KNOX on its head and achieve root on the Note 2, without breaking the warranty.

KNOX is Samsung’s advanced security measure, btw, which can do some good things, but also void your warranty if you root your device using older emthods, or install a custom recovery, thus aiming to don’t let you install your favorite custom ROMs in CM, AOKP, PA, etc.

Here, we will be covering removing KNOX-enabled bootloader from the Galaxy Note 2 and flashing KNOX-disabled bootloader.  In the process we will break WiFi. But, no worries, we will fix even before you’ll discover it was broken. Yes, promise!


We will also cover the new Galaxy Note 2 Root, that’s able to trick away the Samsung’s latest attempt to discourage you from root in the form of KNOX. Oh btw, this new root is only for those who have upgraded to Android 4.3 on Note 2, and this, have got KNOX installed thereby.

If you haven’t yet upgraded your Samsung Galaxy Note 2 GT-N7100 to leaked Android Jelly Bean 4.3 firmware yet, then do check out the link below.

Warranty may be void of your device if you follow the procedures given on this page!

You only are responsible for your device. We won’t be liable if any damage occurs to your device and/or its components.


To make sure your device is eligible with this, you must first confirm its model no. in ‘About device’ option under Settings. Another way to confirm model no. is by looking for it on the packaging box of your device. It must be GT-N7100!

Please know that this page is meant only for Samsung Galaxy Note 2 International variant, model no. GT-N7100. Please DO NOT try the procedures given here on other variants of the Galaxy Note 2: GT-N7102, GT-N7105 GT-N7108 and AT&T, Verizon, T-Mobile, Sprint and other variants who have different model no.


You must do this pre-installation stuff before attempting to root your AT&T Galaxy Note 2 GT-N7100 in order to avoid any complications later, and have a smooth and successful process.


Back up important data and stuff before you start playing around here as there are chances you might lose your apps and app-data (app settings, game progress, etc.), and in rare case, files on sd card, too.

For help on Backup and Restore, check out our exclusive page on that linked right below.



You must have proper and working driver installed on your windows computer to be able to successfully flash KNOX-disabled bootloader and root your International Samsung Galaxy Note 2 GT-N7100. In case you’re not sure, follow the link below for a definitive guide for installing driver for your Galaxy Note 2 on your computer.



If your android device, or PC, powers off due to lack of battery while the process is underway, it could damage the device. So, make sure both of them are adequately charged and that no power interruption takes place when the process is undergoing — at least 50% battery of the device and laptop is what we would recommend.


└ Use original USB cable to connect your phone to PC.

└ Do not use the procedures given below on Mac (using VMWare) as it works best on proper Windows PC only.


Make sure you’ve backed up you’re device before proceeding.


Download the files given below and save them in a separate folder on your computer (just to keep things tidy, that is).


This guide is divided into two parts. First, installing KNOX-disable bootloader and second, installing root on Galaxy Note 2.


Once you’ve finished downloading the file given in downloads section above, follow the instructions below for flashing KNOX-disabled bootloader on your Samsung Galaxy Note 2 GT-N7100.

Important Note: Backup important files stored on internal SD card of your device, so that in case a situation arises requiring you to do a factory reset after installing the root, which might delete internal sd card too, your files will remain safe on PC.

  1. Extract/Unzip the file on your computer (using 7-zip free software, preferably) to get this file: Odin3 v3.07.exe
  2. Extract/Unzip wifi_fix_for_MJ2.rar file on your computer to get this file: patch.tar.md5
  3. Disconnect the Galaxy Note 2 from PC if it is connected.
  4. Double-click the Odin3 v3.07.exe file to open Odin.
  5. Boot your Galaxy Note 2 GT-N7100 into Download Mode (the image below of the Galaxy Note 2 would help):
    1. Power off your phone first and wait for 6-7 seconds after display is off.
    2. Press and hold these 3 buttons together until you see Warning! screen: Volume Down + Power + Home.
    3. Press Volume Up now to continue to Download Mode.
  6. Connect Galaxy Note 2 to PC. Odin window will show an Added!! message in bottom left box.
    Odin’s screen would look like this:
    If you don’t get the Added! message, then make sure you installed driver as given above, if yes, then uninstall and re-install driver again.
    Also, try another USB port on your PC and make sure you use good quality cable, preferably that came with the phone. Reboot phone and PC and try again.
  7. Load the MJ5BLPatch.tar.md5 file into Odin. Click on the PDA button on Odin and select the MJ5BLPatch.tar.md5 file.
    Your Odin will look like this:
  8. Click the Start button to begin flashing KNOX-disabled bootloader on your International Galaxy Note 2 GT-n7100, and wait until you see a PASS! message in Odin’s top left box.
  9. When you get PASS! message, your phone will restart automatically. You can then disconnect your phone from PC.
    Samsung-Galaxy-S3-ATT-Root-SuccessIf you see FAIL message instead of the PASS in Odin’s top left box, that a problem. Try this now: disconnect your Note 2 from PC, close Odin, remove phone’s battery and put it back inside in 3-4 seconds, open Odin and then repeat from Step 3 of this guide again.Also, If device is Stuck at setup connection or on any other process, then too, try this: disconnect your Note 2 from PC, close Odin, remove phone’s battery and put it back inside in 3-4 seconds, open Odin and then repeat from Step 3 of this guide again.
  10. Congratulations! You have successfully flashed the KNOX-disabled bootloader on your Note 2. BUT when your phone boots up, WiFi wouldn’t be working. But, no sweat, we will fix that too.
  11. Disconnect your Note 2 from your PC if connected.
  12. Close Odin.
  13. Now, boot Note 2 into download mode again as you did in step 4 above.
  14. Open Odin (hint: step 3).
  15. Connect Note 2 to PC and wait for Odin to say Added!
  16. Click on PDA and select patch.tar.md5 which we extracted in Step 1.
  17. Click on Start button to begin flashing WiFi fix on your International Galaxy Note 2 GT-n7100, and wait until you see a PASS! message in Odin’s top left box as shown above.
  18. Your Note 2 will automatically restart and you will now have a perfectly working WiFi.

Now, let’s root the Note 2.


Now, what good an upgraded beast of a device is, if it doesn’t have ROOT privileges. So, let’s unleash the full power of the your newly upgraded monster.

NOTE: After flashing the KNOX-disabaled bootloader, you need to have a ClockworkMod Recovery installed on your Note 2 to begin with rooting.

  1. You will need Clockworkmod recovery (CWM) installed to be able to root your Note 2 using the method below. If you don’t have this, get the CWM RECOVERY FROM HERE.
  2. Copy the file on your Note 2’s Internal sd-card using USB cable in a folder, let’s say, with name Root43
  3. Boot your Galaxy Note 2 GT-N7100 into Recovery Mode:
    1. Power off your phone first and wait for 6-7 seconds after display is off.
    2. Press and hold these 3 buttons together: Volume Up + Power + Home.
      (Note: you should see cwm recovery written at the top. If you see 3e recovery there, it means you have Samsung’s default recovery, which is useless. Install CWM now using link given in step 1 above.)
  4. Now, in CWM recovery, select Install zip from sd-card and navigate to the folder Root43 and select file and select Yes on the next prompt to confirm.
  5. You’ll be immediately greeted with MultiTool Advanced V5 Main Menu.
  6. Select Proceed with MultiTool to continue. You’ll see Index 2 with very useful options but right now we will concentrate on Rooting.
  7. Now, select Next. Immediately you’ll see the following screen for Rooting.
  8. Now, select Root device and click Next. You’ll see the following screen for installing BusyBox.
  9. Select, Inject BusyBox to device and click on Next to continue.
  10. Now after these two options you’ll be greeted with many options like Recovery Flasher, Modem Flasher, Kernel Flasher, Backup and Mass bloatware remover, Restore, etc. Make sure that you choose Do Not Change in all of the screens after Inject Root and Inject BusyBox.
  11. Finally, the Aroma Installer will exit. Now Reboot your device by selecting Reboot System Now in your ClockworkMod Recovery.
  12. Your Note 2 will boot up, but be careful here!
  13. DO NOT open SuperSU app or any app that requires root privileges, yet.
  14. Open Play Store app and search and update the SuperSU app.
  15. Congratulations! Your Samsung Galaxy Note 2 GT-N7100 on Android 4.3 update, N7100XXUEMJ5, has been rooted for good. Now, you can run any app that requires root privileges without any worry.

That’s all. If you need help regarding this, feel free to ask us in comments below.

Confirm Root Access

You must have a new app installed now: SuperSU. Check it in app drawer. However, in case you don’t see it on your phone, try installing the app separately from Play store — SuperSU Play store link.

To check whether you got root access or not, use this simple made-for-this-purpose app, Root Checker.

Feedback Us!

It was easy, right? Let us know what you plan to do now, with root access gained.

Suggestions are most welcomed!

          • David Madden

          • Please give me some time to look into it. it should have worked flawlessly but let’s see. Will revert asap, could take couple of hours though. Pls be patient-er!

          • David Madden

          • vikram

            huff…. finally i managed to root tis N7100XXUEMJ5…..DrKetan_MultiTool_AdvanceV2 was the problem i guess. i tried version 5 which is DrKetan_MultiTool_AdvanceV5 and everythings fine……thanks for replying tho @kapil……and for al those who wants to try DrKetan_MultiTool_AdvanceV5 heres the link…


          • Sorry manz didn’t reply you back. I had to check that only, yes only that, but couldn’t find spare time for that. Thnx for pointing it out, I’ll be sure to update the article with it.

  • Lizzam

    It’s not working on my n7100. the last part, after rebooting after using Multitool, SuperSU just launched as a background process before i could update it. and even if i get to the play store in time (before super Su launches), there are no updates in my play store. that’s the part where my rooting does not work.

    and i can still see Knox in the All tab of the Settings>Applications.

    • David Madden

      same here with the SU part.Come on Kapil please.Iv tried all morning on this and failed 🙁

  • me

    what will this do to my “knox warranty flag”?
    does the N7100 has the eFuse as well? will rooting void the warranty?
    will it stop me from doing future upgrades?

    • It should reset the KNOX, but that’s not guaranteed.
      eFuse isn’t confirmed, yet, but it looks like it is there. Yes, it’s very risky. Don’t do this if you care a lot about warranty.
      Maybe updates will be blocked. But you can always upgrade using Odin, forever.

  • Noos

    Hello Kapil. Hello Everyone.

    Thanks for the tutorial. I’ve tried a few other methods offered on Youtube and on various websites, but none can give me root access. I’m a newbie.

    Following your tutorial step-by-step, I got pass the WIFI RECOVERY stage and everything works well. However, I couldn’t access RECOVERY MODE like I did in the past. Holding down VOLUME +, HOME, and POWER button would just give me a flashing screen of “GALAXY NOTE 2 GT-N71000”, which the texts themselves splitting in two halves of the screen.

    What can be done? Any suggestion helpful would be greatly appreciated.


    • Reggie

      Tried to power off the device. Removed the battery. Put the battery back in. Hold VOL+, HOME, and POWER.

      Same result as above.

      • I will try to find the solution for you… and will get back to you.. 🙂

        • Reggie

          Thank you, Kapil. Much appreciated. 🙂

          • Reggie

            Does anyone have the same problem as I do? Is there a solution to this? Much appreciated if anyone can offer an effective solution.

          • Recovery must have got corrupted… you know, you can start fresh. Install the N7100XXUEMJ5 firmware (find the link above, right before warning section) and then, follow this guide to root N7100XXUEMJ5 firmware and remove KNOX again.

            When you install the N7100XXUEMJ5 firmware, you should be able to boot into recovery mode. And you’ll get KNOX too. So, do that and let me know.

            And very sorry for delay in reply.

          • Reggie

            Status: Solved.

            Hi Kapil. Thanks for your help. I re-downloaded N7100XXUEMJ5 and reinstalled it, as you suggested.

            Accessing the RECOVERY MODE was tricky (but doable). This is what I experienced:

            1. RECOVERY MODE won’t come simply by holding down the three buttons (VOL +, HOME, and POWER). For me, I had to hold all three buttons down for about 4-6 flashing cycles (roughly around 30 seconds), then release them simultaneously. More often than not, it will just reboot the device.

            When I got lucky, the screen will keep dark for a long while (10 secs, perhaps) then it will load into the RECOVERY MODE.

            Don’t know why, but it worked. Now, I’m a proud owner of a rooted android 4.3.

            Thank you so much.

        • Reggie

          Hi Kapil. Do we have any solution yet?

    • vikram

      flash CWM RECOVERY (just a try not sure) heres the link……

      • Reggie

        Hi vikram.

        Sorry that I missed your message. Thanks for your suggestion. I did re-flash the CWM RECOVERY and it worked.

        Thanks a bunch.

  • naveen

    hai sir when I tried this metod, after loading MJ5BLPATCH.TAR.MD5 to odin every time it shows fail message.and at the top left side of my phone it shows unsupported version plz help me .

  • Tinjala Daniel Dumitru

    Every time after loading MJ5BLPatch.tar.md5, odin show me “FAIL” in the top left and even if i try the way that you suggest, there is nothing to do. He give me “Fail” everytime. What you think i have to do?

    • Tinjala Daniel Dumitru

      …and after “FAIL” message, i must reinstall the OS, because immediately after I turn on the phone, he doesn’t run. I say that because of an error you need to restore your firmware. Does not go into recovery mode and sometimes yes and sometimes not, I can get into download mode and then connecting it with odin do I have to restore the OS. In a few words, the message FAIL = absolute necessity to restore the OS then. It is not that this error should be to alter the bootloader that then I’m not start the OS. The data are first saved on the phone, but the phone does not start anymore. Thank you in advance that he will be able to find and fix this problem. Thank you;)

  • Mark

    I would just like to confirm that this is only for N7100XXUEMJ5? Please let me know. Thank You!

  • Atlantisarch

    “If you see FAIL message instead of the PASS in Odin’s top left box, that a problem.”
