My galaxy s8 shut off randomly this morning. It immediately tried to reboot, and shows the Samsung logo. It also has a solid blue light. I've tried resetting it using VolDown+Power and it will vibrate after 10 seconds, and show the logo again but goes no further than that. At one point it even showed the T-mobile screen but then rebooted again. When left alone it will just stay on a black screen with the solid blue light. I know there was an "Urgent" update that came through on it, but it had only been 2 days since it was pushed to my phone, never downloaded or installed it.
