Bricked one of your.....

Turned a nice expensive speaker into nothing more than a brick, in other words a corrupt fimeware flash which renders it unusable.

Bridling the firmware.....

Bridling usually means bringing something under control, I am not sure what it means in the context above?





Anyway.
Keep trying to flash the DSP, change the port in your device manager and then in the upload app, I found the 33's would not work on port 2, which every other piece of M equipment I have owned has been fine with.

You can use a paper clip and short the two pins to reset the speakers, this is what I did, you need to search the forum for the pin numbers, doesn't seem to be on the wiki.
I think it was pins 1 and 4 from memory but not 100% as it was a while ago.


I can't help you with the 512 though, would have thought it should just work. You checked the cable connections? No dodgy solder joints or anything??

No Darling, I've had it months!
