Bad news, you have a `QM67 Express Chipset Family LPC Controller` so you have ME hardware on board and it is very difficult to remove, continuing...

Probably this is because you have kernel modules mei and mei_me loaded. Try unloading them before running my tool please.

Thank's @zamaudio , that worked:

koppi@x220:~/Desktop/ime/intelmetool$ sudo rmmod mei_me
koppi@x220:~/Desktop/ime/intelmetool$ sudo rmmod mei
koppi@x220:~/Desktop/ime/intelmetool$ sudo ./intelmetool
