Hey, i got my hands on a N9 which fails to boot. I was intending to use it for spare parts, but was wondering if there was a way i could actually get this thing functioning again?

When I plug the N9 in the charger, the notification led does light up. However, I've tried plugging it in my computer and flashing, but the flasher doesn't recognize it (suitable USB interface not found).

If I try normally booting the N9, nothing happens.
But, when I try to power it on while it's plugged in the charger, it vibrates briefly af it it was booting, and the notification led starts blinking in a 2 second interval. Still, the screen stays black.

Anyone got ideas?
