Bios Mods -The Best BIOS Update and Modification Source

Hi,

I asked a whitelist removal, sending my backuped bios, for a Lenovo S400 and the user Sovem sent me a Universal Bios for my laptop.

I've flashed and everything worked fine, except the Windows 8 that is asking for activation.

Current modded Bios: 6DCN96WW
Backuped Bios: 6DCN91WW (V8.05)

Backup files: https://dl.dropboxusercontent.com/u/69743273/result.rar

It's possible to flash back the original Bios in those file?
Flashing i'll get back the activation key?

Thanks
