[REQUEST] Lenovo Thinkpad X1 Carbon Gen 2 20A8 Whitelist Removal & Advanced Bios
#1
Hi,

I'd like to remove the wifi card whitelist on my 2nd Gen Lenovo X1 Carbon. I've created a flash dump with the BIOS Backup Toolkit on Windows. I have access to SPI flashing hardware so it is not a problem for me if this flash chip is write protected. I would also like to unlock the Advanced menu (for configuring DVMT) but I can request that in another thread. 

If there up to date documentation about how these firmware mods work? I'd like to be able to do it myself in future.

Device: Lenovo X1 Carbon 2nd Gen (2014) 20A8
Bios:  7CCN26WW (1.13)
Original Wireless Card: Intel Dual Band Wireless-AC 7260

I'm happy to donate for the whitelist removal.

For other people finding this thread. I managed to patch my own BIOS to enable the Advanced menu and to disable the whitelist. https://www.bios-mods.com/forum/Thread-G...#pid119048

Model: Lenovo Thinkpad X1 Carbon Gen 2  20A8  (20A8S05S00)

PCI ID:  8086 08B2

Installed Bios 1.35


Manufacturer Bios Download: https://download.lenovo.com/pccbbs/mobiles/gruj32us.exe

EDIT: Sorry last upload was wrong, correct file in place now Smile

CH341A  Bios Extract: http://www.mediafire.com/file/lliv6lihwv...2.bin/file

I am new to this and need to install BCM943602BAED.  I extracted my bios using a CH341A and Clip.  Will I flash it back using the same tool? Compare showed both extracts identical.  I need whitelist and advance bios settings.

Thank you!

Hi
Your bios is rewrite protected
Bios mod can be flashed using SPI-programmer+SOIC8 clip only

I’ve got the tools I think. I’ve got the clip that clips into the bios chip, that’s how I got the DUMP. Is that what you mean? Sorry if I’m mistaken

Hey - sorry to dig up and oldish post, but any chance you could send me the non-whitelist bios for the 20A8?

I don't have windows, so can't use most of these tools. Your help will be greatly appreciated.
