hi, I'm brock. I recently "fixed"my
zte score. If you have installed the proper files,
and possibly even if not, you should power off
then hold down the power button (on top),
the volume down button (on the right top side),
and the camera button (on the lower right side).
Continue to hold until it powers up. You should
see an option for factory reset. Choose this
option then choose to reboot. this will take you
back to a like new phone.
