Bad Bios Flash - Adapter Not Found

Wow... I feel like a screw up. I've been saving up FOREVER... and I finally scrapped enough money to build an $800 computer, $200 of it being for a Sapphire 5770 Vapor X. It was a great card, but I always had issues getting display. After 5-15 reboots later, it would finally display (regardless of the monitor, used my HDTV and my old 19"). It was incredibly unstable and I found out it has 720/800 shaders. Well the bios were what probably messed the card up a bit, because it was one of the few in the batch of cards with incorrect bios installed. So I went ahead and flashed it, like Sapphire told me to but not through them.

I picked up a copy of the Asus 5770 bios, supposedly they were better anyways and would work with my card. I popped up a bootable USB, got into DOS, and flashed like any other time. My card quit working after reboot...

Now I was screwed, I got the 5 beeps and no display. I picked up a PCI card to use temporarily because I thought I could reflash it with the Sapphire bios they told me to use   .

I get back into DOS and atiflash now doesn't respond to the flash "Adapter not Found"
Ok... I type atiflash -i
"No Adapters Found"

Great. I was using a Geforce PCI as a primary until I can get the card working. I won't be able to afford another one for several months and I'm already excited to use my new system. I already emailed in the UPC code for a rebate like a dummy (they wanted it in 5 days or less!) so I can't access that for the RMA (the card is actually defective on top of this).

I heard borrowing a second card and then crossfiring would fix it... but I doubt it!

Is there ANY WAY to fix this. Please help. Greatly appreciated -Dereck
I know how to reflash it if only it stopped saying "Adapter Not Found" and recognized it.
