USB Mass Storage Mode 4.1.1 (root?)

[TheNameless666x]

So my sister accidentally deleted the folder with all her pictures on her HTC One X 4.1.1, and while we are finding many sites on how to recover the photos, apparently, it can't be done without USB Mass Storage Mode. As it turns out (I'm sure many of you know this by now), 4.1.1 no longer features USB Mass Storage Mode. She has tried the app Dumpster, and many tutorials on recovering loss data on HTC One X, but none of them work.

Does anyone know of a sure fire way to recover the photos? Is there a root that offers USB Mass Storage Mode, and if so, will rooting her phone allow her to recover the deleted photos? Any help on this will be truly appreciated.
