[Verizon HTC One (M8)] jsplit:
Cant reboot phone after upgrading firmware from 4.4.4 to 5.01

I'm new to using ADB, but I followed the instructions closely in the tigerstown 3-15-15 firmware post. After flashing the firmware, I can't reboot my phone, and can't get the phone to go back into fastboot to try to reflash it. What I see now is : HTC in center of screen with triangles containing asterisks in each of the 4 corners of the screen

Here is a copy of my command line data during the flash.
