Hello Charles I'm happy to assist you here.

Do not close this chat screen. I'll be giving you a call.  

OK. Try the following steps and let me know if it works 

Hold down the Power button and Volume Down button at the same time for about 8 seconds until until the display turns off, the phone vibrates and the the Samsung Galaxy S8 start up screen appears.

At that point you can let go of the buttons and the phone will boot up normally.

Let me know if works. I'll be standing by
