The tech support is always very busy and it may take a few days to answer. In the meantime if you want to try to update again, remember that whatever firmware version you are installing, it is always better to use the latest Origin Connection (in this case the latest is the one you can find on the forum in the packages with the preview 1.3), even if you want to get back to 1.2.5.
Also, when you power up the Origin, before attempting to change the preset, does it make sound?
