I don't clearly understand your question. The situation is when I updated XStream from 7.8.1.1 to 10.4.0.3, the installation software asked me to update FPGA, Microcontroller and Panel microcode. I said yes and the oscillo lost all additional options. After that, the control panel (knobs, encoders) isn't working at all. And when I tried to downgrade to 7.8.1.1 back, all the additional option were back, but the control panel is still not working.
