This morning my HTC One said "Process System Not Responding" and restarted. Odd, but okay -- unfortunately it kept doing it over and over in a rebooting loop. I tried doing the volume down + power to get into the bootlauncher to factory reset, but that didn't work, it just kept doing a rebooting loop. Fastboot USB gets stuck in <waiting for device> mode.
Here is the information from bootlauncher:

I would greatly appreciate any advice!
