Default Need help getting stock multimedia content

Hi greetings from Argentina.
By mistake I've reflashed my SGP311 and deleted all stock content (Videos, Music, Pictures).
Searching the forum I've found 3 stock videos.
I don't remember how many audio files and pictures where in the internal memory at the moment of purchase.
I'd like to keep them for backup reasons. I thought that Sony Flash Utility would download them with the firmware, but this is not true.
Will you guys help me with a list / original file location inside the tablet / download links for this content.
Tablet is a SGP311.

Thank you, sorry for my English.
