Lenovo Z 50-70

Hello there!

I would also like to ask you for help removing the whitelist limitation on my Lenovo Z50-70. My current wireless card is qualcomm atheros ar956x and I'm trying to upgrade it to Intel Dual Band Wireless 7260ac, yet I encountered the same error (unauthorized wireless card...) as others.

Here is the backup of my current bios: http://ulozto.net/xpUsmzDi/lenovo-9bcn25ww-rom .

Thank you very much for your help!
