It doesn't really help, but consider visudo next time - no possibility of mistakes (you'll need to export VISUAL or EDITOR first though...)

well, i can do a "chgmode 0440 /etc/sudoers" to set the suggested mode, but "sudo gainroot" still fails, this time wit "suduo /etc/sudoers is owned by uid 29999, should be 0".
now, attemting to change ownership (using "chown") fails: root permission required.
so, i need some help here:

From a Linux box:
ssh root@<IP ADDRESS>
default root password is "rootme"
Edit: You would need open ssh or dropbear installed on the 770.

well, i decided to reflash. fortunately i had a a backup which was only two hoers od. so it was no big deal.
here's what happened:
i added some lines to /etc/sudoers and afterwards this file ended with
permissions: -rwxr-xr-x 1 user root.
when trying to do "sudo gainroot" this fails and i et "sudo: /etc/sudoers is mode 0755, should be 0440".
well, i can do a "chgmode 0440 /etc/sudoers" to set the suggested mode, but "sudo gainroot" still fails, this time wit "suduo /etc/sudoers is owned by uid 29999, should be 0".
