@rilme not sure how you tried a hard reset. Try this first:
Press the ***Volume Down*** + ***Power key for a few seconds and then select*** ***Power off.***
Connect your Samsung p[hone to your computer with the USB-C cable. Hold down the ***Volume Up*** and ***Power button*** at the same time for a few seconds.
Release the buttons when the ***SAMSUNG*** image displays and then wait for the ***Recovery mode*** menu
Next use the ***Volume keys*** and select ***Wipe data/factory reset*** and use the ***Power button*** to accept
Select ***Factory data to reset*** and confirm with the ***Power key.***
Next select the ***Reboot system now*** with the ***Power button again.***
