I keep getting "Permission denied" when attempting to manually enable/disable data. Even trying to type "svc data enable" in terminal it says the same.

Normally I wouldn't care, but I have all these NFC tags that I programmed to disable/enable data among other tasks, and it never works. Inside SuperSU app log it just reads ...

svc data disable
Permission Denied

Any ideas are more than welcomed..
