Get a different sd card and try to boot it with a fresh image to make sure the board is not broken.

If it boots the only way to debug this further is to help yourself to an USB-TTL converter to get a serial console to the board.

But I need really repair the old image.

I assume you connected a serial console to get this information?

Anyway as far as I see there is a problem with dns resolution.

Check if /etc/resolv.conf containing valid dns server addresses.

Check if you can ping a known IPv4 address like 141.1.1.1, 8.8.8.8 or 9.9.9.9

It seems like for any reason the script did not stop here as it should...

I`m connect directly to OPI .  (desktop version)

 

The /etc/resolv.conf  is the same like version where armbian works fine connection.

 

I have no possible to ping any address

Missunderstanding. Please try to ping any of these adresses: 141.1.1.1, 8.8.8.8 or 9.9.9.9

 

Check the output of ifconfig if it makes sense and matches your local area network.

The same

Regarding ifconfig is missing information inet netmask broadcast.

 

I just type

~sudo ifconfig eth0 (my dedicated IP) netmask 255.255.255.0 up

and works.

 

But after reboot is still not connect

?

The cheap and dirty way would be to add ifconfig eth0 (my dedicated IP) netmask 255.255.255.0 up to your /etc/rc.local

The correct way would be to check /etc/network/interfaces as the static ip should have been set there.
