Bios Mods -The Best BIOS Update and Modification Source

Below is the the link of BIOS file, Lenovo provided, as their newest BIOS for X1 Yoga
This is for the 3rd Gen model (20LD) 

My specific  unit is 20LD-CT01WW

https://download.lenovo.com/pccbbs/mobiles/n25ur17w.iso

https://support.lenovo.com/us/en/downloads/ds502368

The version of this BIOS is currently 1.27

I am looking for WWAN whitelists removed

Please let me know if you need any other information.

Edit:

Unit comes with a Fibocom L-850LG  I believe the Ven:ID for the PCIE connection is 8087:7360 however there is also a 8087:0AC9  However this device seems to create a virtual USB device to communicate to the PCIe connection.  I am trying to tape the PCIE connection to force into USB mode.  I have tested taping the PCIE pins and booting which then I get a blocked device as the USB interface is not whitelisted.    

Edit: I was successfully able to cover pins 49-55 boot the system without the WWAN card.  Set system to sleep then insert the L850-GL Card.   Once resuming system from sleep the unit does show the USB L-850-GL as device 8087:095A

Therefore this works to get WWAN working under linux however if system dies I have to remove WWAN card boot than reinsert after sleep (S3) this just is not practical for daily use.

Thanks a bunch

I figured I would need a SPI-programmer+SOIC8 clip. So I purchased one. If anyone can help that would be amazing! Thanks~

I would like to remove the whitelist also. I've bought a different wwan module and it's only possible to activate it if I plug it in if the notebook is running and not cold-booting. I have NO idea at all how to flash that but would be willing to assist for whatever needs to be done well at least nearly whatever...

btw. my bios version is 1.29

Hi
Your bios is rewrite protected
you need SPI-programmer+SOIC8 clip
P.S. it is possible that your bios has a RSA signature

Hi I dump the bios with programmer. I can unlock advanced menu, but could you please help remove the whitelist

What exactly did you change? Are there any updates on WWAN removal? Finally: How do I flash this? I'm used to *fl1 and *fl2 files.

Thanks

Did the modded bios 1.41 work?

Hi
ALL mods are personal...need your bios dump only

Is this thread alive?

I want to remove the whitelist with the same model too.
