[REQUEST] Lenovo Z40-75 & Z50-75 (A4CNxxWW) Whitelist Removal

[mitrich77]

After several hours research, lots of trial and error, i made it! 
Here is a working BIOS for the Lenovo Z50-75 (AMD CPU), with no whitelist at all!
You can use every friggin' wifi-card you want!
You will need the SPI-programmer to flash the BIOS to the chip!
Download Link (Sendspace)
Download Link (Dropbox)

It's 100% working!
Thanks to BDMaster, who helped me alot in the beginning, and inspired me to learn more!

Hi!  The download links you posted no longer work. Can you please upload it to new fileshare! Thanks a lot!

So i have found a already moded bios that removes the whitelist so that i may update my WIFI in the laptop.

my 2 problems is. 

1. can i just use his/hers bios update or do i need to mod it somehow to fit my machine ?
ive trying reading alot on the forum and i cant seem to get confirmation one why or another.


2. how the heck do i flash the bios.
ive tried a lot of tutorials / guides from other laptops but i cant seem to finde one that fits the Z50-75 lenovo.
i get all sorts of errors depending on what i do.
tried from dos and got told that the capsule wasnt a secure capsule and the winflash tools told me that a signature wasnt found and so on.

i am a newbe at this so I am sure im doing something wrong but im 10 hours in and want to both learn and get this done.

i hope someone here can help me.

With regards
