[REQUEST]HP 15s-fq1009ng Bios unlock

[goro93]

Hello and (late)merry Christmas,

maybe somebody can help me. I want to unlock the advanced Menu of my HP Laptop.
I think HP has a special security, cause the Bios itself is not "crypted" i can open it in UEFITool/AMICP/PhoeinxTool.
but if I flash it back via SPI-Programmer i get a blackscreen, if i undo the changes and flash it again all is fine.
There has to be a kind of "CRC" check, cause if i only change one vaule with a Hex editor i get a blackscreen (Laptop truns on, fans are spinning, Screen "lights" up but remains black)

-Model: 15s-fq1009ng
-Bios type: AMI 
-Bios Rev.: F.07
-HP BIOS Link: https://ftp.hp.com/pub/softpaq/sp99501-1...p99790.exe   (086C8.bin)
-SPI Dump Link: https://www.sendspace.com/file/u1x5xp

Thanks
Nico

Hi~~
I base on your dump bios to made few modify.
Please try re-write them by SPI programmer and test which one can boot again.
