Welcome to the forums Ted.
I see you have done a factory reset, but I would suggest another. Do it in recovery like this.
Power off your phone again. Hold both volume buttons
and the power button
at the same time. When the phone vibrates, let go of the power button but keep holding both volume buttons
. In a few seconds you should be in the recovery menu. Use volume buttons to move up/down and power button to select. *if power button doesn't work, use your home key*. Go to wipe data/factory reset
and select it. Next, select format cache partition
