Have you tried pulling the battery to see if that changes anything?

If doing a full factory reset doesn't fix the device, try a device re-initialization with Samsung Smart Switch / Samsung Kies. The below KB has information on how to do this. You'll need to download the software from Samsung Smart Switch™: Transfer Contacts, Music & More
Drwho31, I know this has to be frustrating for you. Lets see if we can get past this. Please try taking the SIM card out that is located under the battery. You just slide it while applying a little pressure. Leave it out for a minute and reinsert. If that doesn't work let us know.
