If there is no factory activation log on the server, Apple simply refuses to activate this product altogether, so just making up a new device ID cannot work. You can swap chips from another clean but broken device and assume identity of that device to activate, however you have to swap all major chips together since they are encrypted and matched to each other on both local and server end. Breaking these pairings will likely result in refused activation or immediate bricking. However there has been recorded events of new (not icloud locked) devices been locked by someone else, because iPhone 4 has been hacked enough to reprogram IMEI and other internal IDs. So malicious users can obtain IMEI/serial pairs, use the hacked iPhone 4 to trick icloud to lock other new and not locked devices, then scam money from the victims.
