Wrote the first part of Erisroot instructions. Sent reboot command and it never rebooted. Only sticks on the three android screen. When I push Volume down for Recovery, it only flashes and then goes to the Red Exclamation point (bootloader, I believe). Tried running a RUU on it but it is not detected by it. Have been able to send some fastboot commands but most come back as Remote: Not Allowed. Any suggestions would be appreciated.
