I would like to put custom logo on my old HP ZBook 15 G2 with BIOS version M70 Ver. 01.26.
I tried to follow the instructions in Solved: Using HP's CustomLogoApp.efi - HP Support Community - 7306958 but it seems it does not work on my Laptop/BIOS.
Also, I tried CMSL: HP Client Management Script Library (community.hp.com), but I am getting this error (I'm running PowerShell in admin mode) :
PS C:\Windows\system32> Set-HPFirmwareBootLogo -file mylogo.jpg

How to update the image or clear the current one, because the laptop has one already available from previous owner.
