Exclamation Reverse polarity ESC damage

I have a speedpassion retention pro ESC and I've accidentally connected it negative to positive, and so broke it! Has anyone have any experience or advice about this? Or should I just bin it?
Thanks
Stuart

you might get away with just damaging the reverse function, forward and brakes still ok

I've literally just done this to my LRP Flow in a moment of absentmindedness. I suppose it's not a bad return being my first reverse polarity in over 25 years!

I plugged mine in the right way to find the fans still worked, but on trying the throttle it stopped the fans etc. Stripped it to find the fet board wiped out in a couple of places, so thats ready for the bin.
