I've flashed it and now my screen is almost blank.
After the first reboot, it shows a glimpce of the status bar and that's it.
If I long press home button, it shows the message that there are no recent apps.
If I press on/off button, it locks the screen but, when I unlock it it remains blank.
If I long press on/off, it shows the usual options.
I will now try another reboot.
