New tool fastbootd is included into recovery. Userspace fastboot works from recovery and is launched if: 1) - Dynamic partitioning is enabled 2) - Boot control block has 'boot-fastboot' value into command field The bootloader is expected to load and boot into the recovery image upon seeing boot-fastboot in the BCB command. Recovery then parses the BCB message and switches to fastbootd mode[2]. Please note that boot script is expected to handle 'boot-fastboot' command in BCB and load into recovery mode. Bootloader must support 'reboot fastboot' command which should reboot device into userspace fastboot to accomodate those changes[3]. Another command that bootloader must support[3] is 'reboot recovery'. This command should simply reboot device into recovery mode.
