Hi Matthias , all
first for all a big sorry for my delay 8-)
Yes , I solved my issue and now all seems to be OK .
Below my steps so can be useful for other guys
/etc/init.d/boot start
dmesg | tail -n 20
mount /dev/sda1 /mnt
cd /mnt
mtd write openwrt-ar71xx-generic-tl-mr3020-v1-squashfs-factory.bin firmware
reboot -f
Now you can continue with post installation steps
Bye
Pietro
