5. After you have made your selection(s), Click Next to perform the
upgrade.
If you enabled Check Firmware Version, the Utility compares the
device’s firmware level with that of the upgrade files. If it finds
that the device’s version is higher than the upgrade version, it
brings up a dialog box informing you of the situation and gives
you the option to Continue or Cancel.
If you didn’t enable Check Firmware Version, the Utility installs
the upgrade files without checking whether they are a higher level,
or not.
As the Upgrade proceeds status messages appear in the Status
Messages panel, and the progress toward completion is shown on
the Progress bar.
