You knew the risks, bricking was a possibility they warned about. If you weren't willing to accept the risks, shouldn't have signed up.
But read that thread, may help.

I agree with Xandros9, my 1020 has taken a good few flashes though. That wasn't a photography pun either.
Maybe you should have taken notice of others and not joined them by trying to take a preview as a near RTM, or even joined in because you were tempted. At least not with such a cheap phone, Microsoft may have wanted you to buy a new one. :)
