+## List of volumes (UBI)
+
+| dev    | size       | type    | name         |
+| ------ | ---------- | ------- | ------------ |
+| ubi0_0 | 8507392B   | dynamic | "ubi_Config" |
+| ubi0_1 | 5332992B   | dynamic | "ubi_k0"     |
+| ubi0_2 | 21078016B  | dynamic | "ubi_r0"     |
+| ubi0_3 | 5332992B   | dynamic | "ubi_k1"     |
+| ubi0_4 | 21078016B  | dynamic | "ubi_r1"     |
+
+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.
