Troubleshooting (courtesy XDA Developers)
Problem#1: If you keep getting SuperSu has stopped notifications constantly then follow these steps to fix:
- Uninstall SuperSu (Dont worry you won't lose root access)
- Now download SuperSu again from playstore
- Doing this installs SuperSu on /data/app partition where it won't get stopped by KNOX
Problem#2: If Fix no1 doesn't work for you then try this out:
- Download Terminal Emulator from the playstore.
- Launch it and type the following code:
su
pm disable com.sec.knox.seandroid
Note: This will disable the Knox apps which prevent SuperSu from running
Problem#3: If none of the above steps work to disable Knox. Then try the following:
- Using any Root Explorer go to /system / app & / system / priv-app and delete all the apps having the word Knox in it. Also delete their corresponding odex files.
- This should work without fail. But doing this modifies your system partition and you may lose OTA functionality temporarily.
