The backup of B models is creating 3 files - boot.bin, root.bin and kernel.bin.
However to create the restore file we need too fillup the space between boot.bin
and kernel.bin (therefore the attache blank.bin file) and to add a MTD tag into
the NAND memory right after the root.bin ends up (therefore te mizi_tag.bin file).

The NAND map is as following

boot.bin - 0 -> 317FF (202752 byte)
blank.bin - 31800 -> 527FF (135168 byte of FFh)
kernel.bin - 52800 -> 2627FF (2162688 byte)
root.bin - 262800 -> 41FBDFF (66688512 byte)
mizi_tag.bin - 41FBE00 -> 41FFFFF (16896 bytes)

To create restore file simply execute following

copy /B boot.bin + blank.bin + kernel.bin + root.bin + mizi_tag.bin fw_backup.bin

then burn with JTAG the fw_backup.bin file (it contains OOB blocks) to NAND or boot you DSO,
enter vivi bootloader, replace it with supervivi. Due no USB support in vivi you must use
here xmodem on both sides -> therefore execute on vivi prompt following:

  load flash vivi x

select on PC side the supervivi file and wait until uploaded and flashed.
Then power cycle DSO, enter supervivi prompt and run the menu by typing "menu" and 
use "r" for restore the fw_backup.bin to your DSO. 

On PC side use terminal application to upload (via xmodem) the supervivi to DSO
and dnw.exe to upload fw_backup.bin to DSO.
