KOS Update/Downgrade
IPcore :kontrollers can only run KOS 5.3.30 or higher. All IPcore :kontrollers will be shipped with a working KOS. This KOS prevents an OTA to a version lower than 5.3.30. However, USB update to lower versions cannot be prevented and will not work. A USB KOS Update to the latest release version always be installed to fix this.
