Developer Disk Images for iOS 17

[Lautarob1]

Xcode 15.3 has DDI images under [XcodeApp]/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/ up to 16.4 and new DDI are on a different location and not specific for the iOS version (iOS_DDI.dmg). Now, the previous ones have an associated dmg.signature file, which is not the case for the later.

Is there a way to make ideviceimagemounter works with the new type of DDI?

Thanks!

You need to figure out where Remoted is running, it setups a VPN tunnel to the device. Once you have the IPv6/port of the tunnel, you can establish communication to the RemoteD service. From there, you have to lookup to see if there's a developer disk image already on the device, try to mount if present, otherwise you have to get a TSS request to Apple for them to give you an authorization to upload and mount your disk image based on the device provided information. It gives you a Nonce that's sent to Apple and you receive the authorization back.

Once you have the authorization, you can upload the image & mount it. Unfortunately none of that process is implemented in libimobiledevice.
