Unfortunately it appears that lenovo has killed off downgrading from the 1.41 bios version, therefore i can't use previously whitelisted bios versions for my specific model. Humbly requesting for help with whitelist removal. Thanks guys.

Hello. I`m wondering if the bios mod posted here works for the 4174-P5G model of the T420s also, as I want to mod it.
