I see that i have exactly the same problem as Alfred, while creating loop image my phone reboots, i redownloaded everything 4 times. I tried doing it under backtrack but i'm getting error while it tries to mount /tmp/n950loop (or something like that - i tried yesterday so can't remember). It gives me permission deined. oh, and almost forgot it's live cd linux so may that's a problem. Currently after restoring original files (by apt-get, post 251) i can't play any video except ripped from YT 480p vids (mp4 probably h264)
