This helped me by using the down volume first worked with the bixby and power button. The technician did not know to try this method. Thanks. BTW, I didn't loose any data.
This issue isn't that unusual. Same thing just happened with my S6 (yet to be resolved) and just searching this site I see evidence of it since the S5. Seriously put a dent in my love for Samsung
Only had my s8 a couple of months. Went to check it this morning like usual and one of my apps was acting up so I restarted my device. However, it froze up getting to the carrier logo (AT&T). Restarted it again and same outcome. Rebooted in recovery mode, wiped cahce, same problem. Did a factory reset, problem persists. Im going to be taking it into an AT&T store today. Really bummed I lost all my files and pictures.
This just happened to me. The phone turned off itself 2 hours before. I then noticed when I got home about to place the phone on wireless charger that the phone went into blue downloading screen with a bunch of stats text. One line had "fuse blown." Waited an hour for download and nothing happened. I then tried hard reset with power and down volume and got the phone back to normal boot.
Things seem to be fine. Hope this is not the start of a persistent problem.
