+        When a new firmware gets flashed, its status is marked as, "first_boot".
+        That is an unreliable (uncommitted) firmware. A user may choose
+        to revert back to the previous committed firmware on the subsequent
+        boots. Clicking on the "commit" button calls "mg_ota_commit()" function
+        which commits the firmware.
