I do not know if this is the right forum ...

I have a firewall NETASQ U70, it worked well and I had to do a hard reset

since when I'm on console, I get the following message at startup:

Unknown Flash Type

and after 5 minutes, I have a prompt "Login" but no account works.

I do not have a backup, and I do not have either (more) maintenance Netasq ...

any idea ?

thank you for your help.
