Contact SE as a first port of call, and explain.

You can press other certain key combinations whilst powering the phone 'on',
and that way kick-start some other process and it may work, or work enough
to reflash.

If you can't be bothered with contacting SE (I'd contact them in your
circumstance), then try davinciteam.com - although others exist, I've only
ever used that. Seems good for reviving dead phones, check the forums out
first though.
