How to turn off Developer Mode

I have an app that filter’s my son’s phone (netspark mobile). It isn’t working on his M2 because it says I need to turn off developer mode in order for it to work. What can I do to turn it off? I tried ##6960## but that isn’t working. The developer options are still there under accessibility.


In Settings, Dev, you can switch On or Off USB Debugging (usually needed for some special programs, I don’ t know what do you mean by filtering the phone). To deactivate Root, go to Recovery and do Clean Data

Reflashing the firmware should do the job.
