Omninas KD20 installation problem

I have a Omninas kd20.

I uploaded firmware :
from :

Conforms to the Openwrt instructions.
This is the "snap" version. Something went wrong.

After rebooting the device, I logged in as root,
but I couldn't do any further installation and configuration.
The openwrt directory is missing, missing wget, opkg.
I admit that without them my knowledge of Linux is there
insufficient to deal with the problem.
