Once again I will state - If you are unfortunately plagued with the call Apple with a provided Code, then you are at the mercy of Apple Tech. Even if you change the injected values over and over again, your rig will still throw up the Code message. There are two sure fired ways to overcome the problem, the first way is to call Apple and hope for a sympathetic tech person who will remove the block.
The second way (I don't really like to advocate this method as it encourages illegal cloning) is to use the values from a defunct Apple iMac or the like, owned and previously registered by you and no longer connects to any Apple Services.
