For me 08445 worked. It is F42, I updated it to the latest version through windows 11 on HP 15BS018NQ (F75). And after that followed the guide on [URL]https://poweradm.com/hp-manufacture-programming-mode-unlock/[/URL] to remove the messages and restore serial number.

Motherboard: CLS50 LA-E791P REV: 1.0. (2017)
