No such extraction happens, just a black screen.
Can you give me a log of what happens? Ie. 'adb logcat'?
Start with a clean 'datafiles' folder and retry it again - then give me the log. It must be failing somewhere for some reason - but I need to know what it is.
EDIT: Just tried here again with a clean 'datafiles' dir - it's a black screen for maybe 15 (or 30 secs tops) at first startup but after that it should be running. So the extraction is going fine here on my end at least.
