It looks like you are using ASA 5506 that is running FTD (Firepower Threat Defense). Thus, the only way to perform a password-recovery is through a software re-image:

I hope this helps!

Hi,

Yes I saw that but now I'm stuck.

In fact I enter confreg without option like this:

rommon1> confreg

rommon2>

and now I'm stuck with that mode cause for some reason I'm not able to use again the ESC or send a BREAK signal in putty or HyperTerminal.

That's my issue.

Thanks you,

Thanks

Do you think the re-imaging will get me out of that mode of confreg?

Thanks.

Yes, follow the steps in the guide in the link that I posted above. You perform the re-image form rommon.
