CCC - Series 3+ fault

Hi,

I have an old Series 3+ CCC PLC controller on my desk. Unknowingly, I downloaded a series 3++ image to it....

It seems like this might have bricked it properly. It now only flashes the fault lamp with no way to make the serial connection again, or accept any commands from the engineering panel.

Question is, is this recoverable somehow? Or is it time for it to go to the e-waste bin?

Thanks!
