So I have a c-dsp 8x12 that i was running some of the original 1.xx software on. I had no issues there and used it for many months. I haven't used the 8x12DL in well over a year because i got a new car and was installing a system. This particular system is designed around using the remote as a volume knob. i dont have the OLED version but the original. Anyway, I am trying to update the firmware. Following the instructions perfectly. I do everything im supposed. Afterwards, i read the log and get the error

Dsp settings file not found
Panel firmware file found
Failed to receive upgrade response. 

and then the remote firmware file is still there. 

What does failed to receive upgrade response mean? Does that mean the update failed? Obviously my controller isnt showing lights or working either. How do i test if the firmware went through?

I noticed that in the software there is an "upgrade dsp" and upgrade controller option. Are these newer options  to upgrade firmware rather than using an SD card? 

I did the upgrade dsp with no issues, however I am getting the same, "failed to send upgrade request" from the controller upgrade option

I'm having the same problem! Now the remote has a blank screen. Can someone please help?
