Hello Klem,
looks like you are one of the Heros here helping people get the most out of their kit, I too have a Lenovo Y50-70 NON TOUCH with poor WiFi Functionality and I am seeking your assistance in unlocking the WiFI whitelist as there will be no more BIOS releases for this laptop could I ask for all features to be unlocked i.e. Advanced Options and vbios for the attached BIOS.

I used the Universal BIOS Backup ToolKit 2.0 to extract this BIOS Backup. Thanks for your assistance!
