This is the same Arduino sketch I used to brute-force the EFI Lock but I have implemented a set of conditional loops to wait the 1, 5 and 15 minutes cycles that the iCloud Lock PIN implements. I still use the Teensy 3 for automate this attack which gets done with minimal intervention, just plug it and thats it.
This is specially useful for those who dont have an apple store nearby or those who just dont want to deal with "The Geniuses".
