FastBoot Fail. Help!

    I am trying to root my new Galaxy Nexus. I have unlocked the bootloader already. When I try to copy a boot image through fastboot, it fails. In the bottom right corner when I am in the recovery screen it says "fastboot status FAIL Invalid Command" Then why I try to flash anything it says FAILED (remote: Invalid Command). Here is my complete command history:

    C:\android-sdk-windows\New Folder>adb devices
    List of devices attached
    0146975A0201B01B device


    C:\android-sdk-windows\New Folder>adb reboot recovery

    C:\android-sdk-windows\New Folder>fastboot devices
    0146975A0201B01B fastboot

    C:\android-sdk-windows\New Folder>fastboot boot boot.img
    downloading 'boot.img'... FAILED (remote: Invalid Command)

    C:\android-sdk-windows\New Folder>


    Any ideas?

    Hey I'm having the same problem. Everytime I enter the bootloader it says FAIL Invalid Command as well, could you go into more detail about how you fixed it? At what point did you pull the battery? Thanks.

    are you having this at the exact same time in the process as the op?

    Yeah every time I plug in my Nexus while in bootloader mode the bottom corner instantly shows the FAILEDinvalid command. Unlocking worked just fine though following the same Droid-Life instructions.

    I just turned it off and pulled the battery out. I let it sit for a minute, then turned it back on and booted into the bootloader with both volume keys pushed down. Everything worked fine from there. Does the fastboot devices command recognize your phone?

    Actually I tried the process from a different computer and everything worked! For some reason my particular computer wasn't running fastboot correctly and you suggested. Thanks for the help though!
