Default How to recover file in internal storage?

I dnt know what Ive done last night
But all the files in my internal storage are disappeared.
I mean the image file.
So any way to find the file out?
My device is a Sony Xperia SP , which is rooted but with locked BL.
please provide possible solution as much as u can/__\
I really need ur help as there are too many important and valuable photos there.
Please help!!

PS.Never ask me to use MSC mode instead of MTP, as my photos are save in internal memory
Undelete and Remote for Android are tried but useless
