[REQUEST]Thinkpad T450 display whitelist or/and bios downgrade
#1
Hi,
First thank you if you tried to help me.
I'm here because I do not fully understand a trick. You can see here a tutorial : http://forum.notebookreview.com/threads/...t-10297196

I can't do it because I do not understand how to extract the fl1 file into the  thinkpad X1 gen 3 bios .exe fill (No .fl1 are found when opened with 7zip)
You can found this bios here : https://pcsupport.lenovo.com/fr/en/produ...s/ds101975

Also, here is my bios backup and screen edid : https://www.sendspace.com/filegroup/4Wgj...ZvafM8QNDw

Also, if you know how I can downgrade my bios (I need fl1 file and flash with a 3rd party tool right ?) let me know

Thank you for your attention, have a good day

Hi,
Thank you for your help !
Can you let me know what is supposed to be ? Is this an old T450 bios or the X1 gen 3 bios ?

Also, can you let me know how you managed to extract it from the .exe file if you did

Best
