Hello good day,

I would like to unlock my BIOS too, but having some difficultties dupming my current bios for attachment here.
Would you be able to help me out or point to the exact instructions to do this?
And why would an unlocked bios requested before in this thread not work if it is the same version?

Kind regards, Mike
