Error 280: Failed to disable write protection for the BIOS space!

Only using an SPI Programmer We can rewrite into Eeprom Chip the Bios Mod !
Look here :

If You will get the tools I will help You to reflash back your Firmware Mod !

Could you upload a modded bios?

I will flash as soon as I get the programmer.

You have to upload the Full Dum Firmware (read Eeprom Chip) as I have to patch the file
You get from Eeprom !

Firmware is composed by these Regions (more chunks) :

Descriptor
ME
GbE
Bios
PdR

Your actual file Bios Backup is Bios (Region only) and Firmware is bigger so writeing
the Bios Mod relatively to your Bios Yoou will corrupt definitively your Laptop !

I didn't posted to avoid errors !!!

Hello you,

I'm trying to use a graphic card (with Exp Gdc + ngff m.2) in my wifi slot. However, I received a black screen in the bios when I tried to use the Exp GDC. So I'd like to remove the whitelist.
Also, I "passedby" connecting my card after the bios, but now the problem is that I can't use my e-video because the d-video is enabled. I want to disable my d-video.

I'm a newbie here, and I don't know the proceeding of creating a custom bios. Can you help me?

The information about my notebook and bios is here or in the attachment.

I would like a bios unlocking mod and a whitelist removal mod as well. 

This is the bios version I want to mod.

Thanks in advance!
