[REQUEST] Lenovo Thinkpad X1 nano remove whitelist

[muk0920]

Hello.. I use the laptop X1 Nano Gen1 (20UN-CT01WW). I want to use other WWAN card but, I can't use it. Because, it was whitelist!! 

So, Please help to remove the whitelist in the BIOS 1.44 (N2TET66W).

I want to attach my bios backup file, but i can't it.
Because, "Universal BIOS Backup ToolKit 2.0" fails to operate normally with an "Can not identity the bios!!"..

Please help me how to operate this toolkit.
Thank you.
