Bios Mods -The Best BIOS Update and Modification Source

I have trouble updating the firmware of a HP laptop. The downloaded EXE self-extracts another EXE which runs but shown no GUI and I can't query it for command line options in PowerShell.
I found AMIUCP and it opens the second EXE but I don't know which 256Kb sized ID holds the signature file (required to do a Win+B update from USB).
Could somebody please extract these files from me from the F24 version found here:
https://ftp.hp.com/pub/softpaq/sp139501-...139780.exe ?
Thank you in advance!

You need to extract all from UCP and compare it with the .sig file, then you can locate the stored entry.
