[Q] Desire bricked topic

Hi,

After trying to install a stock rom through RUU, the screen of my phone went black, and since then the phone doesn't start any more. The battery is full, and when I press the power button, it vibrates once, but nothing happens. I tried accessing the recovery mod, and the bootloader, but nothing works. My phone is bricked, and I want to know if there is any software solution to unbrick it.
Could any one help me with this?

Thanks for any answer
