Question Is this adb code valid today?

You don't generally need to be rooted for adb settings. Try it and see, the worst that can happen is you'll get an error message. Also, if successful and after you have reset the password, rerun the second adb command but with '1' instead of '0'.

I tried it but it doesn't work. Do you know any solution?
