/etc/itus/factory_reset.sh is:

if [[ `df | grep -c overlay` == "1" ]]; then
        umount /overlay
fi
sleep 1
mkdir -p /factory_reset
sleep 1
mount /dev/mmcblk0p1 /factory_reset
sleep 1
cd /factory_reset
sleep 1
rm ItusrouterImage
sleep 5
rm ItusbridgeImage
sleep 5
rm ItusgatewayImage
sleep 5
cp ItusrestoreImage ItusrouterImage
sleep 10
cp ItusrestoreImage ItusgatewayImage
sleep 10
cp ItusrestoreImage ItusbridgeImage
sleep 10
cd /
sleep 1
umount /factory_reset
sleep 1
umount -a
sleep 1
reboot -f

in other words, ItusrestoreImage is just the source of the router, gateway and bridge images.

The boot segment should look like:

-rwxr-xr-x    1 root     root      35862152 Nov 26 03:04 ItusbridgeImage
