First a reminder about my images. *.img.xz means it is a compressed multi-partition image. You need to use xz to decompress it before writing it to SD Card.
- .rootfs.tgz is just the root file system partition contents. Only needed to quickly get back to the original flash contents
- .boot.tgz is just the boot partition contents. Only needed in case you wreck something and can no longer boot.
- .md5sum are md5 checksum files you <should> use to make sure the associated file was downloaded properly.
s5p_mfc_load_firmware:179: Firmware is not present in the /lib/firmware directory nor compiled in kernel.
