Ok. You can post here or send me your bios dump, or upload your file bios dump into any fileserver and post the link.

In Lenovo ThinkPad X250, any modified bios can be flash using hardware SPI programmer only, exactly the same as described in the first post of this thread.

So, for creating backup (dump) of bios you need to use hardware SPI programmer only.

Yes, I know that. below is link to my bios dump prepared by SPI programer:

Hi!

What happens now if you install your WWAN modem into laptop?

I want to replace my old wwan card to faster one. When I change wwan card to new one I receive message " 1802: Unauthorized network card is plugged in - Power off and remove the network card (1199/9078)

2101: Detection error on SSD1 (M.2)"

My old wwan card is: Sierra EM 7345

My new one is: Sierra EM 7455

Hi,

I need to remove white list wwan modem from lenovo x 250 bios. I have a bios .bin file from my laptop.  

Can some one modify by bios?
