How to Fix Android 4.3 Jelly Bean Rooting Problem for Galaxy S3/S4/Note 2/3

After updating Samsung galaxy S3/S4/Note 2/ Note 3 to Android 4.3 jelly bean update which contains the new security from Samsung "Samaung KNOX", you might face a problem if you tried to root your device by using CF-Auto-Root method or other methods.

This might happened because of KNOX security, it block/disable SuperSu app and you will see this notification after the first boot.

"Unfortunately, SuperSU has stopped" 

"Unauthorized access to a secured area has been blocked"

In some cases you will not see SuperSU after rooting in your application list
You can enable it by going to Settings / More / Application manager, Swipe to DISABLED tab and Enable SuperSU app.

How to fix KNOX problem :
1. Go to Google Play, Search and update/install SuperSU app

2. When you will open SuperSU for the first time it will ask you to update the SU binary
3. Tap on "Continue" then "Normal" not the "CWM/TRP".

4. SuperSU will detect Samsung KNOX security and will ask you to disable KNOX, Choose "OK"

5. After displaying "installation success!", reboot your device.

Done !
Now SuperSU and root access should be working fine for you.

How to fix "Unfortunately, SuperSU has stopped"

John Giosso

Download and install the latest APK for SuperSU like MrW0lf suggested.

I was having the same exact problem (unfortunately, SuperSU has stopped), so I downloaded the latest UPDATE-SuperSU file and extract it to have supersu APK, put it on my SD card in my phone and installed it from there.

It was strange because the version that was already on my phone was the same 1.89 version that I downloaded, but regardless, when I clicked on the APK, it saw it as an update, it asked to disabled knox, and worked like a charm.

[No Warranty Void] Root Android 4.3 for Samsung Galaxy S3 GT-I9300

Samsung has blocked rooting the international version of the galaxy S3 GT-I9300 by using SafeRoot method, which was completely safe, easy and it doesn't void the warranty of the phone nor trip flash (binary) counter.

I have found a way to make "SafeRoot" root the galaxy S3 GT-I9300 on the latest android 4.3 jelly bean like any other devices.

Requirements :

• I9300_Root_Kernel file
• I9300_MK6_Kernel file
• Odin3
• Installed Samsung Kies or Samsung mobile USB driver
• Saferoot file

Instructions :

1. All the process WON'T wipe your data, but back it up just incase this process corrupt your data.
2. Flash Root_Kernel.tar.md5 file by odin3 in PDA or AP section.
3. Make sure Re-Partition is NOT selected.
   
4. Root your device using SafeRoot method by following this guide : [No Warranty Void] Safe Root Android 4.3 for Galaxy S3/S4 Note 2
5. Flash back the current kernel of your firmware MK6 until Samsung update it by Odin3

Congratulation, your galaxy S3 GT-I9300 is rooted on the latest version of Android 4.3 jelly bean without tripping flash (binary) counter.

YT video link : http://www.youtube.com/watch?v=3gYjoW22h7c

Notes:

• Download and install manually busybox if the tool is failed to install it.
• Use this guide at your own risk
• This process and kernel files ONLY for the international version GT-I9300 and ONLY for Android 4.3 jelly bean.
• Normally this process will continue to work until Samsung starts to push Android 4.4 kitkat to the S3 (DON'T use it on 4.4 kitkat, it will brick your device).
• You will not be able to receive OTA update, but you can update your device at any time by Kies or Odin3. 
• This process is tested by me and worked on all the latest Android 4.3 jelly bean firmwares.
• To unroot your device --> Open SuperSU app / Settings / Full UnRoot.
