Forensics on ipad .img wont mount in Kali

I am attempting to do some forensics on my iPad. I am following along with this article from sans.. on page 13 is the start of the Jailbreaking section...I would like to mount the image and then find the files listed on the following pages.

Model A1219...I did redsn0w 0.9.14b2 the iPad is not 3G and I don't have a passcode on it.

I installed openSSH and did

ssh root@192.168.1.120 dd if=/dev/rdisk0 bs=1M |dd of=ios-root1.img

I can't get it to mount though...or couldn't find anything when trying to use Scalpel

tired this

mount -t hfsplus -o ro,loop /media/psf/Home/ios-root1.img /mnt/hfs/
mount -t hfs /media/psf/Home/ios-root1.img /mnt/hfs/
mount -t hfsplus /media/psf/Home/ios-root1.img /mnt/hfs/

dmesg | tail gives me hfsplus: unable to find HFS+ superblock
