I don't know how you've tried this but it should be possible to it bring down. However, as most applications and services of DR1000 are started in the X session (including the display update mechanism and IPC) there is not too much you can do without X running.

A software component (sysd) on the DR1000 checks for firmware updates when an SD card is mounted. If it finds one, it will ask you to install it and - when confirmed - hard reset the device. Pressing the reset switch does exactly the same (though without the recommended proper shutdown). The hard reset causes the system to boot into a special 'upgrade' mode - independent of the normal kernel - where it overwrites the root file system, kernel and other system parts when necessary. After the installation it reboots for a normal 'soft' boot.
