I worked in the firmware industry for over 30 years. The common practice with any FW load procedure is to first check model number of the target device and verify that it is the same model as the new FW. If not, then refuse to do the load. This is true even when the same FW base is used for multiple products. In that case, a different FW build is done for each of the various models, and each build will work only for its specific model number.
