Product: HP EliteBook 845 14 inch G9 Notebook PC (544M1AV)
Operating System: Linux

I just received a brand new EliteBook 845 G9 that shipped with a BIOS version from April. I did install Linux on it right away (Arch Linux, kernel 5.19.8), but everything worked 100% out of the box. I checked the BIOS updates and noticed the latest release had some security fixes, so I updated to the only available one from the software site, v.01.02.01 Rev.A from August 19, 2022. This update is causing all sorts of USB and PCI bus errors that are not recoverable. Any manner or reset or settings changes haven't fixed anything.

I need that original BIOS that the system shipped with, I don't know the exact revision number, but it was dated some time in April of 2022. My system is practically unusable with the current available BIOS. I have tried accessing the HP public FTP to search for older revisions, but am unable to connect.

 

[Update]

I was able to check for available platform Softpaqs using the CMSL, but still the only system BIOS/Firmware available for the 845 G9 is the 01.02.01 Rev.A version from 08/19/2022. Either the 01.02.01 Rev.A BIOS needs to be fixed, or the factory BIOS that the system shipped with needs to be made available.

[Update 2]

BIOS/Firmware version 01.01.12 is the last working version, and is not available anywhere as far as I can tell.
