Still asks for password.... Power on, manufacturing mode, booted into bios, went to security, checked default factory settings and asked me for administrator password.

You can just flash the original BIOS and you got all information back. But there is a chance that touchpad may not working properly. Need to install serial IO driver to be able to detect touchpad.

Yes i already entered all the info that is necessary! From the sticker on the cover, but it asks me that Cirrus calibration thing. Cirrus seems to me like audio. As for the the touchpad and other peripherals, all work ok.

Do you have any progress on this problem? I think try to flash again the original bios. You'll loose the trackpad and mouse but after install serial IO driver everything works just fine.

Re: Help unlock HP 830 g9

Ah yes, this that stupid Audio Calibration data thing on some newer models. You can't edit it via the BIOS menus like the feature byte etc, only that UEFI proprietary tool that HP uses internally where you can calibrate it.

But alternatively you can edit more CMOS string values manually using a USB EFI shell with the "UefiBiosConfig.efi" tool.

If it's similar to va "HP EliteBook 860 16 inch G9 Notebook PC" you can try my personal dumped calibration data for the audio chip. (Hope it doesn't screw it up)

Anyway make a bootable USB EFI Shell, extract the zip into the root of the USB. Navigate to EFI\Boot and copy my dumped cirruscalibrate.txt into there.

Then boot into your USB EFI Shell (might need to turn off secure boot).
Make sure you navigate to the USB drive then go to EFI\Boot

UefiBiosConfig -getconfig=cirruscalibrate.txt

You can also dump your existing config using:

UefiBiosConfig -getconfig=cmosdump.txt

Edit it in notepad or using the edit command, then restore it with:

UefiBiosConfig -setconfig=cmosdump.txt

If the error goes away and the audio fixes itself, then horray!
If you get a red screen of death on reboot about some stupid programming mode, run this:

UefiBiosConfig -setconfig=lockmpm.txt

Good luck

Then boot into your USB EFI Shell (might need to turn off secure boot).
Make sure you navigate to the USB drive then go to EFI\Boot

UefiBiosConfig -getconfig=cirruscalibrate.txt

Whoops I meant

UefiBiosConfig -setconfig=cirruscalibrate.txt

like in the screenshot

Couldn't edit the post a 2nd time haha
