Simply changing an 0 to an O or 1 to l works and removes iCloud locks, however find my iPhone will never work again. These machines can also remove iCloud locks as the iCloud is SN based by apple.

(Edit: they no longer recirculate IMEI numbers due to federal laws prohibiting IMEI number changing, as well as they mark them inactive in their internal program and yes they can see that if you ever call in for support) You need both the SN and IMEI in order to make sure apple servers don’t brick the phone, which yes, is built into the phones software. This is used in a situation when the SN and IMEI needs to be recirculated due to a total loss board or warranty claim where the activation chain has to be the exact one as before. This is the machine used by Foxconn which is who repairs apples iPhones and iPads.
