Pretty old post, but this same exact thing happened to me and my F90BT, SD #2 would crash at 3%, I think I read somewhere that the handbrake bypass may cause it but I am not sure. I did the unofficial 3.0 with the x910 files and everything except road names in 3D and my SD music "scans" or skips around all the time. Not sure what happened or why the official crap didnt work but I spent the money and all it did was break my system, what a POS! I would like to now what the issue was with this if anyone knows. Thanks!
