Only the first 4 partitions with erasesize 0x20000 should be manipulated using mtd devices, the fifth partition ubi_device contains the rest of the NAND and is to be manipulated using ubi volumes

List of volumes (UBI)

dev	size	type	name
ubi0_0	11046912B	dynamic	“ubi_Config”
ubi0_1	10539008B	dynamic	“ubi_k0”
ubi0_2	26284032B	dynamic	“ubi_r0”
ubi0_3	10539008B	dynamic	“ubi_k1”
ubi0_4	26284032B	dynamic	“ubi_r1”
ubi0_5	8507392B	dynamic	“ubi_framework1”
ubi0_6	8507392B	dynamic	“ubi_framework2”
ubi0_7	37838848B	dynamic	“ubi_apps”

To back up a volume, cat or dd the appropriate /dev/ubi0_X device to a file or pipe, to restore a volume, use the ubiupdatevol utility (or just do it safely via the WebGUI)

This ONT supports dual boot.

Volumes ubi_k0 and ubi_r0 respectively contain kernel and rootfs of the first image, while ubi_k1 and ubi_r1 contain kernel and rootfs of the second one.
