I now have no issues with ADB, able to do push/pull and everything fine when the phone is booted into the OS, but now I'm getting no response from "fastboot devices" when I am indeed in fastboot (not hboot) and connected to the same computer I've been doing fastboot with. After entering the "fastboot devices" command it doesn't even display an empty list of connected devices, it says nothing at all.
