Thank you sti! I tried this under windows for a Kobo Touch. Unfortunately, without success. Maybe somebody can tell me what I am doing wrong. This is what I did. I had already a copy of the internal sd, so I skip this part.

On the pc:
With a hex editor, changed 0 to 1 at position 0x80040. (Or is the assumption that the position is the same as for the H2O wrong?)
Wrote the image to a sd with USB Duplicator Image Writer.exe.

Inserted the sd in the external slot of the (already running) Kobo.
With telnet:
Code:
###
mount /dev/mmcblk1p1 /mnt/sd
mknod /mnt/sd/dev/mmcblk1 b 179 8
mknod /mnt/sd/dev/mmcblk1p1 b 179 9
mknod /mnt/sd/dev/mmcblk1p2 b 179 10
mknod /mnt/sd/dev/mmcblk1p3 b 179 11
##
rm /mnt/sd/etc/udev.tgz
##
sed -i -e 's/mmcblk0p/mmcblk1p/g' /mnt/sd/etc/init.d/rcS
##
umount /mnt/sd
mount /dev/mmcblk1p3 /mnt/sd
dosfsck /mnt/sd
##
umount /mnt/sd
reboot
