Notebook Operating System and Recovery

Hi!

I'm trying to update the BIOS of my notebook. The notebook is running Linux and I don't have any Windows system available.

I read this post:

It sounds quite promising, but it is still not working. I tried to rename files in many different ways but still without success. My usb drive looks like this now:

├── Hewlett-Packard
│   ├── BIOS
│   │       └── New
│   │               ├── 68IMT.BIN
│   │               └── 68IMT.sig
│   └── BIOSUpdate
│               ├── CryptRSA32.efi
│               ├── CryptRSA.efi
│               ├── HpBiosUpdate32.efi
│               ├── HpBiosUpdate32.s09
│               ├── HpBiosUpdate32.s12
│               ├── HpBiosUpdate32.sig
│               ├── HpBiosUpdate.efi
│               ├── HpBiosUpdate.log
│               ├── HpBiosUpdate.s09
│               ├── HpBiosUpdate.s12
│               └── HpBiosUpdate.sig
└── HpBiosUpdate.log

When activating Bios update in the Bios setup and rebooting, a "HP BIOS Update" screen appears. It is counting down the seconds or I can choose "Apply upate now". In both cases the system hangs and the screen is frozen.  The HpBiosUpdate.log always contains the same messages:

01/28/17 08:47:17 EFI HP BIOS Update 2.7.1.0 Started
01/28/17 08:47:18 Failed init of SMBIOS data

It would be nice if someone could give me some hint how to get this running.

thanks
