Start rescueOS according to the documentation with the flasher utility, then Code: mmr mount /dev/mmcblk0p2 /mnt/maemo/home mount -o bind /mnt/maemo/home/opt /mnt/maemo/opt mount -o bind /dev/ /mnt/maemo/dev mount -o bind /proc/ /mnt/maemo/proc mount -o bind /sys/ /mnt/maemo/sys mount -o bind /dev/pts /mnt/maemo/dev/pts chroot /mnt/maemo /bin/ash rm -rf /usr/share/fcam rm /etc/modprobe.d/fcam.conf This should remove all traces of the fcam-drivers on your device. It might be overkill for the removal to use the chroot, but ...?!
mmr mount /dev/mmcblk0p2 /mnt/maemo/home mount -o bind /mnt/maemo/home/opt /mnt/maemo/opt mount -o bind /dev/ /mnt/maemo/dev mount -o bind /proc/ /mnt/maemo/proc mount -o bind /sys/ /mnt/maemo/sys mount -o bind /dev/pts /mnt/maemo/dev/pts chroot /mnt/maemo /bin/ash rm -rf /usr/share/fcam rm /etc/modprobe.d/fcam.conf
