Undelete files on ext4 filesystem.

Use extundelete 0.2.4 version.

DESCRIPTION
       extundelete is a utility that can recover deleted files from an ext3 or ext4 partition
       extundelete uses the information stored in the partition's journal to attempt to recover a file that has been deleted from the partition.
       There is no guarantee that any particular file will be able to be undeleted, so always try to have a good backup system in place, or at least put one in place after recovering your files!

extundelete --restore-all

Kali ships with old version wich is not working in some cases!
