Flashing ROM to Device with no operating system

[pbutin]

Hi,

My ATT Tilt 2 just went dead--while I was using it. The only screen I can get when I attempt a hard reset is the red/green/blue/white one that has RHO300, etc. at the top and "Serial" or "USB" at the bottom (when plugged in).

How can I flash a new ROM to the phone when it is in this condition? I've never tried this so will need some help. I've tried to flash using the USB cable but the flash programs say there is a communication error. Is there a way to flash from a micro card?

Just need some good advice--not ready to lose all my files and peripherals from WM yet.

Thanks so much for any help you can offer.
