* Insert the external microSD card in the ereader and boot it up.
* Get a shell on the device, either via Telnet, SSH or some sort of terminal emulator.
* On the ereader shell, mount the rootfs as read only and clone the internal memory into the external microSD card:
```
umount /mnt/onboard
mount -o remount,ro /
dd if=/dev/mmcblk0 of=/dev/mmcblk1
