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
