Ready to Download, fw is corrupt

[servomec]

Printer is showing this error.  "  Ready to Download, fw is corrupt " I saw a couple other posts that had this issue.  I tried the resets listed , printer do not communicater with USB . I wonder why there is a  TOP SECRET NVRAM reset that is passed by private message.  Can someone send that to me so I can try  fixing it?

I tried the steps listed but still showing "fw corrupt"  and I don't get the HP logo when it powers up.  It does from power off to "fw corrupt".  It is an HP M452dw.  Help.
