Help unlock HP EliteBook 830 G9

[TauroX]

Good day. Please help me figure this out. I can't defeat this notebook. I've tried a million different combinations. If I understand correctly. I need to break the main BIOS so that the EC is rewritten at the moment of the first turn on. I delete almost all information. It doesn't require a password when logging in. But I can't reset the security settings to factory defaults. Maybe I can somehow delete them from the EC flash drive? Please help me with advice.

Thank you very much for your response. But the problem is still not solved. Moreover, now when loading the system it still hangs on the logo every other time. And the BIOS update does not install.At the first boot it gives this message. Is it maybe because of different versions of BIOS and EC firmware? How to fix it?

Hello to all masters. Help. I can't solve the problem with Intel Smart Sound Technology OED. I flashed the original BIOS back. It doesn't help. I was able to remove the password only by flashing someone else's unlocked BIOS. Then I returned mine back. Maybe someone has encountered and solved this problem. Please advise.

I have a suspicion that someone has already tried to unlock the laptop. I did not immediately check whether this error was there before all the manipulations. I am attaching the BIOS and EC firmware. Maybe someone who knows will see what is wrong?

I've had similar issues on Dell laptops when flashing a different bios, i believe something in the bios is paired to the audio chip. Idk of a fix but you can go to device manager and "update" the driver to the MS audio driver and sound will work, you can also use a group policy to prevent it from updating itself (which it will if you just uninstall it)
