Hardware projects / Re: Z420 BIOS mod
April 10, 2017, 02:25:48 pm
Hi all,
my Z420 workstation has latest BIOS J61 v03.91 and Windows 10 Professional 64-bit.
Boot Block Date is 12/28/2011.

I was able to update its ME Firmware Version from 7.1.21.1134 to v7.1.86.1221 (sp71010) from HP website.
However, now I cannot update ME Firmware Version from 7.1.86.1221 to latest download v8.1.65.1568 (sp72520) from HP website.

The command:
FWUpdLcl64.exe -f 81651568.bin -generic
results in:

Error 8727: Firmware update tool failed to get the firmware parameters.

Just the same, if I try update to ME Firmware v8.1.52.1496 from UEFI shell,
the command:
fs0:\efi\boot\FWUpdLcl.efi -f 81651568.bin
results in:

Error 8727: Firmware update tool failed to get the firmware parameters.

I'm sure I am doing something wrong.
Is there any way to succeed to upgrade ME from v7.1 to v8.1?

Thank you very much in advance for any support, feedback or advice.
Cheers, Michele
