[REQUEST] HP Envy 4T-1200 CTO Ultrabook Advanced Menu

[neccros]

Looked and looked and couldnt find this bios modded already so here it goes.

Model: HP Envy 4T-1200 CTO Ultrabook (Non-touch screen)

Current Insyde BIOS version F.25:

Another link to the page for the laptops BIOS.

Looking to access the advanced menu and possibly eliminate the wifi white list. I want to upgrade the wifi card to a AC card.

Thank you!

Moddable only using an HW SPI Program !

So why are some Insydes moddable but this one isnt?? Is it the BIOS or the hardware its on??

This is known like RSA Signature Lock You can find here or on web to see that
HP protected his Bioses using the RSA cyphrature !
Only and not all sp5xxxx.exe can be modded, but none sp6xxxx.exe !
Actualy Donovan6k discovered (studying an trying to bypas this lock) a way to, but We cannot
reflash the Bios Mod so only using SPI PGM is possible like CodeRush posted here :
