That's great news . Could you check whether /opt/busybox-power/busybox-power.symlinks is populated with applets? Also, could you post the content of /opt/busybox-power/busybox.power.md5? You'll find your original BusyBox binary in the same directory (busybox.original). You probably need to run "mountopt" in Backupmenu's root shell before you can access /opt (which will be mounted in /tmp/mnt after running that command)
