Single user mode is a command shell much like terminal, however terminal is a command shell inside a booted graphical user interface.

Disk0 is the disk to mount

Going back and rereading our banter, when I suggested manually mounting disk0s1, you posted the output "disk1s1 the device is write locked"

I hadn't noticed at the time.

In either single user or terminal from recovery, try:
mkdir /volumes/mnt1
mkdir /volumes/mnt2
mkdir /volumes/mnt3
mount_hfs /dev/disk0s1 /volumes/mnt1
mount_hfs /dev/disk0s2 /volumes/mnt2
mount_hfs /dev/disk0s3 /volumes/mnt3

Let me know which if any commands work

mkdir all 3 entered without issue

this returned from mount disk 0s1 and 0s2,
mount_hfs: error on mount(): error = -1
mount_hfs: Invalid argument

However mount disk0s3 worked,
mount_hfs /dev/disk0s3 /volumes/mnt3
-bash-3.2#

cd /dev/mnt3: no such file or directory

so i tried
cd /volumes/mnt3
ls
.Trashes .metadata_never_index com.apple.boot.p
.fseventsd System com.apple.recovery.boot

Looks like a list of directories

Oops I was tired when I wrote that. You were right with the command good job.

That's the recovery partition. S1 will be the EFI partition. S2 will be the target.

Can you go back to the disk utility (from cmd-r boot) and select the "OS" entry beneath applessd and post a screenshot?

Do an inbox search for "recovery" or "FileVault" or just plain "Apple" and sift through the results for a recovery key.

Also, sign into iCloud.com and poke around there for FileVault recovery?

It's an undocumented feature so I don't know much about it
