Hi this shows me in terminal when I wanto: sudo gainroot. Can you help me what to do? I tryed restore to default factory setting, without success.

It can be tricky, because you have to be root to change permissions to that file:
# chmod 0440 /etc/sudoers

Maybe try to remove rootsh package with application manager and then re-install it.

ssh root@localhost
Enter your root password.
chmod 0440 /etc/sudoers

ssh shows connection refused. And in app manager it shows me no applications installed.

reflash it. There's no way you could go into root when sudoers file is not working. Or if luck is in you try restarting and pray that the device autogenerates the sudoers file.

Do you have openssh-server and rootsh packages installed at all maybe?
