Ah, while looking at the code, here's a typo:

Code:

#Restore the RootFS from $backupRootFile
mount -t ubifs ubi0_0 /tmp/mnt/rootfs
if [ $? -ne 0 ]; then
   umount -t ubufs
   $T2S -s 2 -H left -y $y -T 0xF800 -t "  Error: cannot mount the RootFS."; y=$((y+20))
pressAnyKey
break

Should be "umount -t ubifs" I bet.

Then after a few lines he writes:

Code:

$T2S -s 2 -H left -y $y -T 0 -t "  Clearing the RootFS..."; y=$((y+20))
  busybox rm -rf /tmp/mnt/rootfs/*

Here he nukes the rootfs' files. Formatting should replace the "busybox rm" line.

Anybody knows the right way to go? I'm scared to mess with ubifs, I haven't quite understood how it works

EDIT: is it "ubiformat /dev/whatever"?
and [Q] Why do you want to format rootfs just before restoring instead that having an extra command to do that? [A] Because if user formats rootfs with that command and forgets to restore a rootfs tar immediately after, will be left with an unbootable device that has necessarily to be reflashed.
