Woots! I fail hard! I tried to flash my n800 and failed miserably. I started out following this http://www.internettablettalk.com/forums/showpost.php?p=94459&postcount=2
and it fails at the second command on number 14 with a "sutable usb device not found" error http://linuxcranks.pastebin.com/m1c5b5cc8
Then thelastknowngod showed me this http://wiki.maemo.org/Updating_the_tablet_firmware and it fails with this error "Write failed after 0 bytes
usb_bulk_write: Resource temporarily unavailable"
So now I am sitting here with a fairly useless n800. It still boots but it wont load an OS, so I still have hope, but man am I pissed.
**EDIT: I got this to work, but I had to use my girlfriends vista (puke) box, but the flasher for windows is niiice.
