I've recentle flashed the new CM monthly.
As expected, it hasn't been very stable. The screen froze every few days, but removing/replacing the battery solved that.
However now after such a freeze I haven't been able to turn it back on.
The screen, button LEDs stay off, no matter if the phone is plugged in or not. I've even tried another battery without success.
It isn't visible to my computer even in fastboot mode (Vol + & power on), however it will get slightly warmer when plugged in.
