When you flashing your Nokia N9 with the main binary image (not e-mmc image) by option to destroy user data, your N9 will be clean included the stock content such as Music, Picture and Video. It won't occurred if you get the e-mmc image and use this image to flashing your phone. The stock content will be added during the flashing progress included the maps of the region where e-mmc image you used. Picture Nokia Pure Video But to download the e-mmc image, it's a big file (ETA 1,7GB) so for you that don't have a good connection, I have made backup of the stock content from Nokia N9. My backup contain Music, Picture, Video and default Wallpaper of N9 that's you can download separately and transfer into your N9. You can download Stock Content from Nokia N9 here . Hopefully it can help you, thanks. Harmattan not yet died.
