Is there anyway to recover the contents from the internal flash from a non booting n800?

a few days ago I was at a party and when i checked the time on my n800 the screen was corrupted, except for a few icons (it was on portrait mode) and, scared, I turned it off, the next morning I tried turning it on, but it got stuck at the Nokia screen for a couple minute before blinking the screen to black and back to the Nokia screen. The only way to turn it off was removing the battery, since my last backup is from a april more or less, I wanted to recover the files from the home folder in the internal memory.

Is it possible? or should I lost hope and lose my information?

Thanks

EDIT: Somehow I managed to boot the tablet, it's working fine now, made a new backup, but I'm still intrigued by this, I wonder what was wrong...
