[N800] Problem with root
 
After removing libmissioncontrol the N800 became very unstable....

now when i try to write in xterm "sudo su -" appear "Sorry, user user is not allowed to execute '/bin/su -' as root on Nokia-N800-39."
o_O coooool
everything I try to to is a "permission denied" (cat: /etc/sudoers: Permission denied)

I rember that I did from my pc via ssh (after logging in as root/rootme) "passwd -l root"....

I'm really stuck!!!

P.s. i cannot reboot to reach the bootmenu I can only poweroff with the power button!!!!
and "apt-get update" gives to me:
E: Could not open lock file /var/lib/apt/lists/lock - open (13 Permission denied)
E: Unable to lock the list directory

help :(

What about "sudo gainroot" ?

Re: [N800] Problem with root
 
I thougth to reflash my N800 but when I connect the usb cable to my pc the boot menu (magically for me) appears and I cannot use the nokia wizard application to reload the latest firmware.
Now I'm using my IT booting from the mmc2.

1) Is there a way to restore the corrupted/missing file from mmc2 to flash?
2) It's a good procedure disable the bootmenu so I can reload the firmware?

Have you held down the Home key while powering on the device?

ok...don't know why but seems that the bootmenu is fixed...but the "permission denied" problem still exists booting from flash

yes just mount your flash partition and copy the file over,
mounting steps are described in

There is no need to disable it. It gets overwritten with full firmware flash. It is quite harmless so you can also keep it and just reflash rootfs (with linux flasher).

Re: [N800] Problem with root
 
Umm, seems like there is a lot of confusion here. What I understood is that something broke and you have that permission problem with system in internal flash and you can boot from mmc which is still OK, right?

If this is true, than you can boot from mmc, mount internal flash and copy /etc/sudoers or whatever to internal flash, unmount it and try to boot from internal flash again. Something like

1. boot from mmc, open xterm, sudo gainroot
2.
Code:
mount -t jffs2 /dev/mtdblock4 /opt
cp -a /etc/sudoers /opt/etc/
umount /opt
3. reboot and boot from internal flash
