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

[aerou]

Hello dear BIOS Gurus!

I have Lenovo Y50-70 (model 20378) with FHD IPS Screen and nV 960M graphics (if this is of any importance).


I kindly ask (and will donate for your time and help) for assistance with:
1) teaching me the correct procedure
2) removing whitelist so I can use Intel 7260AC instead of the crappy stock Lenovo that drops every 5minutes
3) unlocking advanced BIOS item? What does this unlock? Memory settings? CPU/chipset settings? 

I have read previous request threads. But still I am not 100% about the procedure.


- I downgrade from my version my current 2.00 BIOS bz flashing 1.14 with "BIOSVFEnable=0".
- I use Insyde backup of the 1.14 and send it for modding.
- The person modding the BIOS than uses the 1.14 dump to mod latest version 3.03 https://download.lenovo.com/consumer/mob...cn43ww.exe
- I flash the modded 3.03 using ?

- Will this whole thing keep the embedded OS License?
- There is no way of doing this without Windows, right? :/

Kindest regards,

Julius
