The LORIX Programming Tool has direct access to the LORIX One's internal memory.
It can be used when the USB access is possible to program the LORIX One as it's done in factory. It can also be used in case of corrupted system, for example if you have previously stopped a programming process before its completion.
This method is the preferred way to upgrade from the legacy firmware to the LORIX OS since it's really quick, easy and secure.
This is needed only the first time. Once the LORIX OS is installed, you will be able to do OTA updates.
