How to get zte maven Z812 broken screen turned on

@charlesddavis ,Charles , If it quit working when the display was broken, then you may have to change the display to get it up and running again. Below is a disassembly video 1st link which you can use to open up the phone and look for further damage of components, connectors, etc., and also change your display if up to it. Links 2 and 3 are a display assy. or if only needing digitizer that are available for purchase, which you could try a search on for better pricing perhaps. Good luck. I hope this helped you out, if so let me know by pressing the helpful button.
