Recently I bought a SHA-104.v2. I was setting the system up, and I connected it to the network. I changed the admin usename to another but admin, I also changed it's password. But an unknown reason the admin user changed it's name to 0 -zero- and it was "disabled" so I can't login with it. I also created other users but those doen't have admin rights so I can't restore the admin account. How can I recover it? Best regards
