bricked = no sign of life under any circumstances

Try putting the phone into download mode when the battery is removed. Pull the battery and leave it out. Connect the phone to the PC via USB cable, and hold down vol+ and vol- (but not pwr). The USB cable will supply the power. Let us know if it will boot into download mode using this method.
