Hello,

I have the same problem and could not write to the chip because of the write protection (error 280) . So I bought the programmer CH341A and made a backup of the ROM. The ROM was detected as a 25 SPI Flash Winbond W25X64. Is it possible to whitelist the attached BIOS Backup , so that I can use the Intel AC Dualband Wifi card? The Original Lenovo Bios is : 96CN29WW(v1.15) BIOS.

Thank you very much

All is aligned to Pin #1 from Eeprom Chip to SPI PGM and Pin #1 is set to
Red Wire so other holes on socket are unusefull 10 - 2 = 8 Wink
Do You understand ?
Follow this Guide :

Hello,
I'm a new user here and a Lenovo Yoga 2 13 unlucky owner with bigh issues with built in wifi card.
My notebook has last 1.17 BIOS, can anybody help me to find the easiest way to bypass the with list to install any other M2 wifi/BT card?

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

How to unlock Menu Tabs (Temporanely) Mod (Stinger2k) :

" [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 ... "


2. FalseClock Method

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 :

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 ?
