Ok I see now. The "HW2" in that file name is just a label, just means that the particular firmware file was inteded to be loaded on hardware that is HW:2. You can't change the type of hardware by loading different firmware.
HW - Hardware ID - set at the factory
FW - Firmware version - changes when you load a different firmware file on there
We sent out a factory recall, you will need to get your Berserker reprogrammed to HW:2 at the shop some time (or just be doomed to forever need to manually load firmware updates separately and ignore any on-line requests to update your firmware), then it will take the correct automatic firmware updates over the internet. As I said, some Berserkers (about a dozen) were incorrectly told to be HW:1's before being shipped out. So they will incorrectly accept the wrong firmware update over the internet.
