Default [Q] Need help recovering internal storage

My xtz go stuck in a boot loop so unfortunately I had to reflash ftf with the "wipe data" ticked.

Tablet is now back up and working, rooted with minimal apps and nothing in the internal storage.

I have seen this thread regarding recovering the internal storage.

My question is are there any other methods and does anyone know which partition contains /data and/or internal storage?

I have a 64GB microsd so I'm thinking I could use the dd command to ouput the raw file on to the microsd
