is the phone in fastboot mode?
is platform-tools where you have adb setup?
if you type

Code:

adb devices

what happens? it should show a list of devices connected

start from scratch
1.reboot your phone normally
2.

Code:

adb devices

just to make sure adb recognizes your phone
3.

Code:

adb reboot bootloader

4.

Code:

fastboot oem unlock

make sure that you are using the right directory when typing the commands
