" [SUCCESS] BIOS Lock Disabled Yoga 2 13 & Pro

Hey guys,

I found an undocumented function in our yoga´s (specially Yoga 2 13 & Pro) try this . . .

Hard Reset the Yoga (start a directx game and do that on load) --> pushing down the power key for less then 10 seconds
then push randomly and fast (very fast.. - because I don´t know the exact entrypoint for this)
"FN+F2+R" (it´s a little bit tricky i tried this 1 - 3 times but the function is there...')
Now you entered an undocumented Mode in Mainboard-BIOS with Tab´s shown on this video:

https://www.dropbox.com/s/40uaa8iolbfku6...7.mp4?dl=0

See under Advanced | Chipset Configuration | BIOS Lock --> which is enabled / you can disable it ...

Maybe anyone here´s more skilled in bios modding, try to flash a whitelisted bios with this workaround ... "

Ok I can say that Disabling Bios Lock We can weflash Bios easy so You have to get the Custom Menu and
set into configuration the Bios Lock as Disabled, then save settings and Youcan use the Bios Mod !

Or You can try to use FalseClock Metod :

https://www.bios-mods.com/forum/Thread-R...-EFI-shell

Use an USB Stick Fat32 Formatted for UEFI Boot and respect structure USB_Name:\EFI\Boot

1. Create directory structure EFI\Boot
2. Download BOOTX64.EFI
3. Put downloaded file to Boot directory.
4. Restart and enter BIOS setup.
5. Make sure you have following values:
Legacy Support: Disable
Secure Boot: Disable
6. Reboot and press F9 to boot from USB stick
7. Give commands:

setup_var 0x4AB 0x0

8. Reboot and try to reflash Bios Mos using USB Stick !

Here You can get Efi hacked module :

Hi!

I'm new to this and I have the same problem as the rest here. I hate lenovo for this and will never ever buy their product again. Can someone please help me? And I don't really understand why can't there be any universal modified BIOS? I have the newest BIOS 96CN30WW (V1.16) with my Lenovo Yoga 2 13 and trying to install Intel 7260 AC card.

I hope I did the right thing here:

BIOS backup:

Thanks,

Ok friend,
I said that your Bios Mod cannot be reflashed as your Eeprom is Write Protect and into result file
You can find this error :

Error 280: Failed to disable write protection for the BIOS space!

Unpack It using WinRar 5.20 or above and see !
So now You have to use one of two ways I wrote before :

1. Custom Menu

So just follow the Guide and modify the Variable into VarSore by Flaseclock or just getting
Custom Menu with all Tabs showed to set Bios Lock OFF then the result file will be
without error 280 and We will able to rewrite your Bios Mod !
Do You understand now what have You do ?
Let me know

Hi there,

New user of a Yoga 2 with an i5 Cpu. I have upgraded the HDD TO an M.2 SSD what worked perfect but my upgrade of the Wifi to the Lenovo Intel Dual Band Wireless-AC 7260NGW 802.11ac NGFF Card FRU：04W38 has not worked out so well (unauthorized message on boot).


Bios version is V 1.11 (http://download.lenovo.com/consumer/mobi...x32x64.exe)

it would be great if there was a method to patch / update for use of the new wirless card on Lenovo Yoga 2's latest Bios V1.16 (http://download.lenovo.com/consumer/mobi...x32x64.exe)


Is anyone able to advice offer advice on trying to get this to work?
The Yoga 2 is just a paper weight at the moment

Hello, i own the same computer, a yoga 2 13, and I ordered a 7265 intel wifi card because i can't connect one of the 2 router (a D6300 netgear, with AC wifi) i have at home. I wasn't aware about this whitelist before ordering it of course

So, i ordered the needed tools on ebay to modify the bios (thank you so much Exetico for your post here). Do i need to upload my bios (V1.16 but V1.15 would be ok), or can i use a file you made before for hudson_uk?

Thanks for your help
