The owner of the device on the root galaxy S8

Question

I am trying to raise the internal Demo application to the device owner on my root S8 and you are having problems.

The ways I tried:

1) Providing NFC (as described here )

When using NFC with Android Bean to set the device owner on S8, the message "Unable to create work profile due to security recommendations of your device" is displayed -error

2) Providing Adb (from the console):

Using

dpm set-device-owner my/app/namespace/.DeviceAdmin

in windows console i get the following error

java.lang.SecurityException: Neither user 2000 nor current process has com.samsung.android.knox.permission.KNOX_PROXY_ADMIN_INTERNAL.,com.sec.enterprise.permission.MDM_PROXY_ADMIN_INTERNAL

Adding missing permissions to my manifest didn't change anything.
