Long story short, i was flashing my N9, but after that, images that came/transferred from other device are not shown in the gallery. Only images produce by N9's own camera are show.
I use explorer and see the image files in the same folder with the previous transferred image files.
The weird thing is, images transferred before the flashing are still shown in the gallery.

And now face recognition is not function, although i was activated through application menu.

Any ideas whats wrong with it?
Thanks in advance for the help.
