I have Opticum x403p and I upgraded firmware to the latest 1.3.05, but I have a real problem to connect to internet via ethernet cable. DHCP on "Network Local Settings" is not recognizing dynamic address any more, so no internet connection. After a few tries, I realized that I cannot downgrade to any of old firmwares, so it is locked and I'm stuck. I saw somebody posted it is because in 1.3.05 is changed loader. Anybody has a solution for this?
