I reflashed the N9 to try this new image.

The summary is: great work! Congrats to all involved :-)

There are, nonetheless, a fair amount of polishment to be done. Following is a quick list for reference.
* as discussed before, the system lags often and does not feel responsive
* the graphical interface crashed a few times, mostly while trying to open the keyboard; eventually it worked
* charging works but the battery indicator does not update
* the system started without any ambience (black background)
* after applying one ambience, the app screen still has a black background

I have not yet tried to use the store or update the sw, and currently I do not have a sim card on the phone.

This is hope of a new life for the N9. Well done!
