I would be good if the answer was "yes". And if it is, then I need:

1. Information about your MTD/UBI setup:
	1.1 cat /proc/mtd
	1.2 ubinfo -a
2. UBIFS image: just do
	dd if=3D/dev/ubi0_Y of=3Dubifs.img bs=3D4096
	where /dev/ubi0_Y is the UBI volume node corresponding to
	the "ubi0:database" volume.
