[REQUEST] Lenovo Yoga 2 Pro (76CNxxWW) Whitelist Removal

This is same like FlaseClock Method :

P.S. What do You want to unlock ?

I managed to unlock Advanced tab in the BIOS. And even though 'Wifi' option that I mentioned had nothing to do with the whitelist the Advanced tab turned out to be very useful. In particular there is 'BIOS Lock' option that disables write protection and allows to flash BIOS from Windows (still need to do sleep/wakeup).

Enabling advanced tab turned out rather simple in Linux - just hexedit the EFI var:

Code:

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

Here is a screenshot: http://bit.ly/1NIki9M

Then in 'Advanced' -> 'Chipset Configuration' one can disable BIOS lock. Some more screenshots:

Also there are many other interesting settings to tweak there

Dear PeterQuinn,

What do you know abouy the Yoga 3 11? Can this laptop also be unlocked this way? i tried exactly this manual, except i got a black Ghex screen.
Did i do something wrong, or is this impossible with this machine? I have a SOIC8 + Clip, but i am scared to wreck my laptop.

Any tips or advise?

Regards,
Kirelam

How do I get rid of this white list on my Lenovo yoga pro 2 - I currently have BIOS Version/Date LENOVO 76CN43WW, 3/30/2015. I'm trying to install my AC 8265 M2 and it lists my new device as unauthorized

Hi,

I have a Lenovo Yoga Pro 2 and I am trying to install a Intel 8260. My complication is that I have Ubuntu installed and I couldn't find how to generate the report you require. Sorry if this is documented but I did look.

All the best.

Here You go :

Unpack the Bios Mod and copy the "modified" folder into C: HD root place !
Then open Command Promt with Admin Rights (CLI window C:\), put your laptop
into Sleep Mode (just close the Lid) and then Wacke-Up It (reopen the Lid),
after this execute these comands from CLI window :

cd \

cd modified

fptw -f bios.bin -bios

(or fptw64 for Windows x64)

Let me know
