[Q] Can't find the right memory block for Note 2. topic

I recently updated my Sprint Galaxy Note 2 to android 4.3. Everything went slow, and so it was suggested to hard reset my device. I though I had everything backed up but i didn't. I am trying to recover deleted files. I used the guide I found on this forum here.

My problem is the under /dev/block all the mmcblk files are 0 bytes. Every time I extract I get 0 bytes as well. What should I do differently? Is there a different location I should be looking at?

Thanks
