Hello ValdikSS,
 Please help me to upgrade bios from version 1.43  to version 1.44..
 I have installed a wifi card need the whitelist removed..
And in your installation process, need to flash the original v1.44 BIOS.. but when I flash the original BIOS, I was prevent to  boot from the new BIOS because of my installed wifi card..
So , how to upgrade my x220 bios? please help me..


This is what I do:

1) Remove unauthorised WLAN and WWAN card.

2) Reboot into Windows and flash original BIOS.

3) Reboot and flash modified whitelisted BIOS.

4) Shut down and install WLAN and WWAN cards.

5) Restart windows.

I have installed macOS in my x220.... and I met the hd 3000 display issue.. So I wish try a BIOS update may solve display issue..
Can I flash BIOS in the windows PE system?
There is a new bios available for the X220, version 1.45 - The changes are only related to the MEBx acces bypass bug. Regardless, can I ask for the unlock on this bios version? Many thanks
