Android's Deleted File Recovery in Linux?

Hi everyone.!.!. Is there any Linux software to recover deleted videos and images from the internal memory of my android.?.?.
Actually i have two phones in which i had some important pictures and videos of my late friend that i really want...
one phone is rooted so i tried diskdigger photo recovery and undeleter but they didn't seem to find all of the pictures and videos in that phone.
and the other one is unrooted so i haven't event touched that.
Maybe the data were overwritten in the rooted one but i would still like to try...
please help me....
