My N9 gets to state where screen shows only black.
You cant see anything, but you can feel feedback when you touch statusbar.
It happens when I turn sreen off and put it to pocket so standby screen goes off after that it wont turn back on.
It seems to break always when I edit mce.ini (N9QT, Powermenu)
and haven't found solution but reflash.

Anyone can help?
Or upload clean mce.ini?

Thanks.
