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

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 everyone, I am wondering if somebody can help me, I got to the point where i've got the DUMP with a file inside called bios0.bios. What do I do now? Thank you, and sorry if I miss something, I'm new to this
I attached the dump bios and the original bios extracted from x1

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

[veggiedev]

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
