Can't get iRobot S9+ password

Hello,

Is there any option that not all the models are able to retrieve the password?

I got the blid from the process of the dorita980, but it says “Error getting password, Follow the instructions and try again”
I tried that few times already and got nothing.

Please let me know if there is any other option I can get the password.
Thanks in advance.

Some body can fix?
