[REQUEST] Lenovo Y50-70 (9ECNxxWW) BIOS Unlock

[Oleh]

I want to unlock my BIOS so I can do something to install Mac OS X on it. What I need to do is: DVMT-prealloc BIOS setting must be changed to 128MB

So apparently unlocking the BIOS will allow me to do this. However, I believe I need you to provide you with my BIOS and it's something I don't know how to do. And even if I gave you my BIOS and you changed it, how would I replace my BIOS with the one provided?

Help would be appreciated.

Greetings! My apologize but i also need bios unlock for the same reason author stated bellow.
But with an exception, i have gtx 960m and intel 4600.
#Upd, successfully installed v1.14 using BDMaster's guide, but they are still some problems, now i cant use my dedicated nvidia gpu.
Can some please help me with fully unlocking Bios and keeping Bios version v1.14 or lower because i need it to Triple Boot OS X

Can I ask which Bios version You got before v.1.14 ?
And why do You want to get the v.1.14 yet ?
Let me know

I had version 2.02 i think, i need to set up DVMT-PREALLOC for OS X to work properly

[infinity133]

Do you suggest to forget about this idea and return to the standart 2 version or even newer?

[BDMaster]

We are using the older version like a door to unlock Eeporm Chip and then We reflash
the actual and better Bios !
This Method is not known from Oleh as He copied all my Codes and Techniques but
some didn't get as I hidden !
In this way We have only a Disalignemnt with EC Code but It not relevant about
normal working !
I am BDMaster not oleh

To use this way I need the Bios Backup of your last Bios used on this laptop
so I will modify this one then You will go back again to Unlock the Eeprom Chip
and finally reflash the Bios Mod v.2 for You !
I didn't revealed this (Sovem has done 1stly Excellent Programmer) as oleh said
that I didn't discovered nothing and all is shared but He didn't shared nothing of
his knowledgemnt (but there is something to share of his ? )
So let me know
Regards

Well, my previous post is irrelevant. I've decided to update to (v3.0) and then to look for other possibilities to install osx. All i need to do now is to unlock advanced menu in BIOS.
Here is the backup:

#Upd I want to use the newest version of BIOS(v.3) so do i need to make a backup of previous used on my pc(v.2) and then reflash to a newer one?
But if i have the latest already installed do i need to downgrade?

Here You go :

P.S. Downgrade to v.1.14 to unlock Eeprom Chip and then reflash this Bios Mod !

How do I check the version of my BIOS?

I am scared to do the flashing of my BIOS because there is a chance of bricking my laptop right? I don't know how exactly do it and I didn't fully understand the instructions provided to me.

Could someone please look into the file I provided in page 1 and tell me the version of my BIOS? I don't know how to check honestly.

How do I run this flash exactly?
