 For the screens and kernel, you'll need to write the data directly, for the rootfs, you'll be able to mount the SD card and copy the files and directories that way. Again be sure to double check everything, as these commands could have disastrous effects if aimed at the wrong places. In this example we will be using /dev/sdf as the device.
