Apple's guidance: If your Mac starts up to a circle with a line through it - Apple Support
Note the admonition to contact Apple Support if this doesn't work.
I tired that several times no change. I did get it to a lock icon but, you have to go to a apple store to have them enter the firmware password. I will continue to try some other tricks to see if I can get back working. Thanks for the reply
