[Request] HP Dv7 (sp50586)

Hello,

I am looking to remove the wifi whitelist on my HP Dv7.

BIOS Link:
http://ftp.hp.com/pub/softpaq/sp50501-51000/sp50586.exe

PCI ID:
PCI\VEN_14E4&DEV_4357&SUBSYS_145E103C&REV_01
PCI\VEN_14E4&DEV_4357&SUBSYS_145E103C
PCI\VEN_14E4&DEV_4357&CC_028000
PCI\VEN_14E4&DEV_4357&CC_0280

Additional Info:
I have found a previous link here but when I run InsydeFlash, I get "ROM file not found". Looking in platform.ini I found the filename blank.

My apologies if I am missing something obvious, but I am new to this.

Thank you.
