Tried again as we speak, set the * to Unlock and erase it from Lock, set it back with the command and restart the laptop, still locked.

I don't see any number like this on motherboard, i see a 6070B0676404 on the chassis but since the motherboard is G1 and the chassis G2 (seems like the customer has built a Frankestein machine here) this number is not relevant to motherboard.
