You could install adb/fastboot on a PC and then using a USB cable hook the rock to the PC using whichever USB port on the rock, it might be the upper usb2 port. Then open a term on the PC and try "adb reboot bootloader" that might drop it to the bootloader at which point try to see if it is locked. If locked try "fastboot oem unlock" or "fastboot flash unlock" or whatever the current command is. Try just "fastboot" and it will show the current commands. BTW, it is best if you install the latest USB utilities from Google on the PC in order to have the most up to date ADB/fastboot to work with.
