The catalog marks this build as unsigned. A normal restore may not be accepted.

Back up before you restore. A restore can erase the data on the device. The identifier has to match, and a file you can download may still be rejected for restore. bridgeOS belongs to the matching Mac hardware and is not a macOS installer.
