If you're certain it's bricked and next step is RMA, then try the paper clip trick. Scary, but worked on mine (flashed the wrong bios)...
My card is still under warranty, so I'd rather not try this.
tried this, totally not worked on my reference card, It seems its really dead, already sent to my supplier for warranties and guess what, they don't ask if its modded or not.. Lol 
I laugh hard reading this..
Actually the OP and I have different scenes, My card is totally dead that couldn't even detect in Bios, there were no signs of fan spinnings or LED lights
so basically I've got no problem RMA'ing it (they can't test if its modded or not)
But even they didn't ask you; they would ask what causes but they don't, so what wrong with trying. Even in some store like Amazon, they didn't ask.
@OP,
you don't do the jumper thing, just reflash your GPU with the correct Bios and you're done.
OP on a direction to do it (smooth repair). But may you give an idea to totally damaged those card to bypass bios checking on RMA.
