A few weeks ago after a facebook upgrade the phone stopped at boot then I did a factory reset and now it shows 'Unfortunately, the setup wizard has stopped' every time I boot up or restart. Also, there's no launcher in default and can't set stock android either. I've managed to install go launcher manually after a lot of trouble but now I can't install anything from the play store. Can't draw the notification bar down either. I bought the phone in July 2017. How do I fix this?
