I have an N800 with OS2008, got it just last week. I was logged in as root via ssh from my PC and edited the sudoers file (using visudo). I then opened X-terminal as user and was able to log in as root using 'sudo su' and entering root's password. So all looked good at this point.

I then logged out and powered off the N800, then powered on to reboot it. It started to boot, screen lit up with 'NOKIA', but when the blue line reached the far right that's where it stopped. After some time the screen dims and then goes dark, turns bright again if I tap the screen. It's connected to the power supply so the battery won't run down.

What can be done to restore my original sudoers file? I saved a copy of the original sudoers on the N800 as well as on my PC.

I don't yet know much about how to use the sudoers file. Below is a copy of the one that's in there now, and probably caused the failed boot.
Code:
Defaults env_check+="HOME DISPLAY"
Defaults env_keep+="HOME DISPLAY"
Defaults env_reset
Defaults:user timestamp_timeout=-1, runaspw, passwd_tries=3
root ALL = (ALL) ALL
user ALL = (ALL) ALL

Did you change the file access permissions of the /etc/sudoers file, by chance?

It should be:

-r--r----- 1 root root

I did not look at the permissions of the /etc/sudoers file after using visudo, so permissions are as visudo left them.

In order to power down, I had to remove and re-insert the battery. Then I tried to reflash OS2008, but the N800 would not go into the firmware upload mode. I phoned Nokia tech support, they told me to send it in for warranty repair.

I don't 'know' but, I read there is a battery that keeps time, and perhaps other status info. Take the battery out for two hours and leave unplugged. Then you should be able to get to the update mode at least.

That sounds odd, to be honest. I can understand to some degree why your device might be hanging during the boot sequence - most likely because a script is either stuck at a password prompt or sudo is failing completely - but for the device to not go into flasher mode doesn't sound like it's connected with your sudo modifications. Could just be a coincidence.... have you tried holding the "Home" key while powering on?

I think you're very lucky to get a repair under warranty, particularly if your inability to flash is due to your sudo changes!

Hmmm, so that could explain why i had to reflash my n800 4 time since i had it (yesterday)... It may well be the sudoers modification (done via visudo, in a way that used to work on n800). I was thinking one third party program was doing it, without finding wich one....

Note that reflashing the tablet always worked here.

Well yes, holding the Home key (Swap Key) while powering on is the only way I know to begin a firmware upload. After having the battery out for some hours I installed the battery and tried to enter flash mode one more time, but no joy. I usually don't break things this quickly, had it less than a week. Anyway, it's no big deal because it's still under warranty.

Hmm, my OS2008 sudoers file is MUCH longer than yours. I haven't touched it.

Not to be as condescending.... But (I think) I noticed that it only goes to firmware mode when actually connected to the computer (I don't think the flash program needs to be running).

I've had startup problems myself, so I won't try it to confirm for you.

Edit; guess I was wrong and removed rude comment.

I wasn't being intentionally condescending - sigh.

Flashing usually works whether you hold the Home button or not, but it's one of those things which people can overlook so is worth asking. If you hold the Home button it will go to flash mode whether it's connected to a computer or not (or will wait longer for a computer to "appear") - if you don't hold the button it will only go to flash mode if it's connected to a computer. Or something like that - holding the button can make a crucial difference. The OP never mentioned it, so I asked. Maybe I shouldn't have bothered...
