Hey y'all.
Two days ago I was using my Nokia N9 and suddenly it started to fail in different ways:
camera failed to start, keyboard failed to show up, 2G/3G inernet connection disappeared from "Connect to the Internet" menu.

So I decided to reboot N9. Then I found that Advanced Power Menu fail to start too.
So I pressed and held power button until device turns off, and turned on it again. N9 didn't turn on completely, it rebooted a few times and after that it had boot up, but with all settings, contacts etc were gone, all buttons and images looked like red squares.
I tried to restore backup, but after reboot it looked like it did nothing.
I tried to "restore settings" without clearing data, it rebooted and icons and buttons looked fine, but all my data, including photos, backups and notes was gone. Applications didn't disappear though.

But things got worse.
Now, after every reboot, device clears all data: contacts, photos, etc disappear.

One interesting thing more:
In settings - Data storage it shows available memory for apps and apps data, but it says "not available in mass storage mode" in user data memory.
It also says "Can't access user data" when I connect phone to PC.
But I still can surf to /user/home in File case.


Any advice?
