Firmware not supported by this system
The firmware currently installed on one of the components is not supported by the overall system, so assist is disabled. This typically happens when components with mismatched firmware versions are combined, for example after a parts swap or a partial update. Updating all components to the latest compatible firmware via E-TUBE PROJECT resolves the conflict.
