Hi friend , We proud You the modifies to apply to your bios to make a Bios Mod and rewrite back !

Here You go for the tools (this modiy is for these Bios Version 76CN31WW, 76CN38WW, 76CN41WW, 76CN43WW) :

https://www.mediafire.com/file/ioicwa2d5...r.rar/file

Here is the explaination :

1. Some bios version are re-flashable as Eeprom is not Locked, but newer versions has Bios Lock, so You can
use the method by "PeterQuinn" (Bios Lock) :

The following are the steps to unlock your bios, and get us on our way to installing OS X on our Yoga 2 Pro.

1 – Boot into Linux 14.04 using UEFI (F12 at startup of Yoga 2 Pro).

I used a bootable USB with Ubuntu, and this guide will assume you know how to create a bootable USB for Linux (and also use Ubuntu).

http://releases.ubuntu.com/14.04/

https://help.ubuntu.com/community/Instal.../MinimalCD

Once booted, you can install to the hard drive, but this guide will assume you will choose Try Ubuntu Without Installing.

Also, only version 14.04 is supported, as other versions may not be able to unlock the bios.

2 – Once in go to Files, select Computer , and verify the following exists:

/sys/firmware/efi/efivars/SCUShowHiddenPage8be4df61-93ca-11d2-aa0d-00e098032b8c.

This is what we will modify to show the Advanced menu tab in out bios.

3 – open terminal (if you have installed Linux already, you may be able to proceed to step 4)

A – enable the Universe repository – (execute this command into terminal's CLI)

sudo add-apt-repository universe

B – update the package list - (execute this command into terminal's CLI)

sudo apt-get update

C- install ghex – (execute this command into terminal's CLI)

sudo apt-get install ghex

4 - Run the code provided by PeterQuinn - (execute this command into terminal's CLI)

sudo ghex /sys/firmware/efi/efivars/SCUShowHiddenPage-8be4df61-93ca-11d2-aa0d-00e098032b8c

5 - This will bring up the ghex GUI

000000 : 07 00 00 00

5 – Change the last value from 00 to 01

000000 : 07 00 00 01

6 – Save your work (File, Save).

7 – Restart laptop, enter bios (F2) and the Advanced menu tab should now be available

8 – Go to the Advanced menu, and open Chipset Configuration

9 – Arrow down to the bottom, and set BIOS Lock to Disabled

10 – Exit saving changes (F10)

Now You can flash the Bios Mod using Intel FPT Tool.

Make the bios mod following the instructions into Tools folder (ReadMe.txt), then create a folder into C:\ root place,
rename it as "modified", copy into it all files from the folder [4].
Open a Comand Prompt with Admin Rights (CLI) and run this comands :

cd \

cd C:\modified

fptw -f bios.bin -bios

(for x64 use fptw64).

These are the Modified modules :
