Did you also select the correct cloudOS IPSW?
The default one doesn't work with iOS 26.3.1.

In your case, you'll need to change the value of CLOUDOS_SOURCE to https://updates.cdn-apple.com/private-cloud-compute/045c5b04d14892c444162a975b69ba46438656e31ee6219173d4ceb3eb99acf6.

To find the correct cloudOS IPSW for your iOS version, match the build number prefix — for example, 23D — and select a cloudOS IPSW that shares the same prefix. You can find the available URLs at https://appledb.dev/device/identifier/ComputeModule14,1.html.
