HTC One M8 Opened Today!!

Hello, I have recently unboxed my HTC one M8 and updated it to lollipop 5.0. I then updated it to android 6.0 and it is now showing a picture of the phone with a red ! Inside of a triangle. I have tried to reboot it using volume up and power it reboots to the same thing, I tried to do everything and it just come up with the same problem. This is my first android device that I have personally owned.

Thanks
Eric

Welcome to Android Central! Which carrier? There have been a number of problem threads about the HTC One M8 Marshmallow update. Talk to your carrier first and let them know that their update has rendered your phone inoperable. Since it's a new phone and it's their update, they should do something to correct the issue, even if it means giving you a replacement.
