I Have a Vodafone smart 4 mini and my brother was messing around on root explorer and may have messed up build.props because when I turn it on it straight after the vodafone thing it goes to a black screen and a loading icon and doesn't go away I am rooted and have already tried to factory reset via recovery mode power button+volume up but it still goes to the same thing PLZZZZZZ HELP PS. I don't have a pc
