    Default N7 UnBrick - Can't Unlock, Can't Flash, Need help

    I am having a locked out problem with my Nexus 7 (bricked)

    Can get into FASTBOOT MODE
    with grouper 3.34 but LOCKED

    N7 UnBrick - Can't Unlock, Can't Flash, Need help-fastboot-flash-fail1.jpg

    flashboot flash bootloader bootloader-grouper-3.34.img
    FAILED - remote: Bootloader is locked

    fastboot oem unlock
    FAILED - see screenshot above
    N7 screen displays "Unlock bootloader?" dialog
    Selecting YES and entering with power button
    produces screen message:
    unlocking now.......
    for a few seconds, then replaced with

    neither USP nor CRC partitions found
    neither USP nor CRC partitions found
    neither USP nor CRC partitions found

    which repeats every few seconds and fills screen.

    Any help or suggestions would be greatly appreciated.
    Thanks in advance,

    Reinstall the adb/fastboot drivers.

    If it's saying that it can't find partitions after running the unlock bootloader command, then that's pretty scary. If the bootloader is erased then the device is bricked, at least until we get a working version of nvflash for the nexus 7.

    I hope you get this sorted mate.

    can someone explain what bootloader bootloader-grouper-3.34.img is ?
    I was thinking it was a recovery but not sure
