Hi,

Please define CONFIG_ENABLE_LOCKSTATUS_SUPPORT macro in fastboot_lock_unlock.h file. This fastboot_lock_unlock.h file reside at <android_root_directory>/bootable/bootloader/uboot-imx/drivers/usb/gadget.

After defining this macro one can able to unlock the android device using fastboot oem unlock command and also able to flash the images using fastboot flash <partition_name> <filename>.

Regards,

Shivani

Hi,

Very easiest way to remove fastboot LOCK from u-boot is comment out one line from "include/configs/mx6sabreandroid_common.h"

/* For NAND we don't support lock/unlock */

build the u-boot.imx thats it. Fastboot is enabled.
