Accidentally deleted stock music video and photos, off my xperia Z5

[Bronnel]

I Accidentally deleted stock music video and photos off my xperia Z5 that came with the phone, I really wanna get them back , I'm so upset that I lost them, I tried to use recovery software without luck, so if someone can upload original sony photos videos and music, that came with the phone I would be grateful, I mean the actual video photos, and songs, not the apps themselves
