Can You ener the tri-color screen? (bootloader)
try holding down volume down key and the power button while you push the reset button with the stylus.
If that works you will be in a rainbow colored screen from there you can plug in the computer to flash a new rom. make sure its CDMA or GSM it is very important..
-if you want to restore the factory rom hold the power button, volume down key, the touch wheel button, and reset with stylus.. i know its awkward, but it works..
Are you sure that you unlocked your phone? the colored screen should sy unlocked on the top somewhere..
