We have been discussing specifications for a detection tool based on requests from customers.
With the current MASAMUNE Erasure specifications, there is a method to obtain the Activation Lock (Find My iPhone) enabled/disabled status over a USB connection.
A customer asked whether Activation Lock could be detected on a device after DFU mode and IPSW overwrite.
To detect Activation Lock, pairing with the iPhone is required. We found that the information can only be obtained after the device shows “Trust This Computer?” and the user selects “Trust”.
Therefore, Activation Lock information cannot be retrieved while the device is connected in DFU mode.
Even if you write IPSW and boot the device after DFU connection, you cannot complete the pairing unless iPhone setup is completed (“Trust This Computer?” will not appear), so unfortunately it is not possible.
We hope this behavior changes in the future, and we will continue focusing on developing detection tools.
