Yeah you just use dd to image either md0 or md1 whichever is the active raid array and it creates a file the same size as the rootfs.img file found inside a MyBookLive firmware .deb
Then I just use the resetbutton upgrade downgrade restore script to install that custom firmware image back. I’m pretty sure it would work on the MBL DUO but I don’t have a unit to test it on.
If you feel like trying it sometime, here is the link
