My N4 seems to have bricked itself, or had some hardware component malfunction suddenly. I flashed the latest PA build on Tuesday and have been running that happily since. This morning, I took a screenshot of something, and the system locked up. I figured no big deal, that stuff happens. Held the power button to reboot, and it hung on the google logo. That's never happened to me before, and thought that was strange. So, I held the power button again and it rebooted afterwards without issue. Thought nothing of it.
Later, I was taking a photo, and the autofocus motor freaked out and the system locked up. Held the power button to reboot, it shut down, and that was it. Now it is completely unresponsive. Have had it plugged to the wall charger in for 2 hours, tried plugging it into the computer and pressing/holding the power button (windows doesn't recognize anything being plugged in). Can't get any response out of it at all.
Basically, I'm at a loss of what to do.
Funny thing is, I was considering ordering a N5 yesterday/today. This has pretty much confirmed my intention to go ahead and order one, but I would like to get my N4 back up and running if possible.
