Unable
to Get Root Access While Being Rooted?
If you
have KNOX on your Galaxy device and you have rooted it, you’ll see a
verification message that pops up every time SuperSU is called for action by
some apps on your device. The message runs like this:
“SuperSU tried to access system in your device without
authorization. This action was blocked.”
OR
“An application attempted to access system on your device
without authorization.”
OR
“Unauthorized access to a secured area
has been blocked.”
You can
get rid of this annoying thing easily by disabling Knox service and its agent
apps. Remember, once KNOX is aware of SuperUser on your phone, it’ll block its functioning and
you might not be able to use any root app. In case you are unable to get root
access (after rooting your device) because KNOX prevents SuperSU in doing so,
do this:
2.
Extract the zip and open the folder.
3.
Go the folder named “common” and copy the Superuser.apk to your phone.
4.
Install the APK manually (do not forget to tick Unknown
Sources option under
Security settings of your device).
5.
Now launch the SuperSU
app on your phone and it will ask you whether or
not you want to disable KNOX.
6.
Select OK.
It will then tell you that KNOX has been successfully disabled.
You should
now be able to enjoy root access on your Samsung Galaxy device. If you want to
remove KNOX from the device, use the method given below.
