It's sounding like it really is a brick.
What do you have it connected to?
Chip, power, USB cable?
Use Voltmeter to confirm 3 Volts. Do the LEDs flash when you plug it in?
Is the USB cable functioning with some other device?
If connected to other circuits can you disconnect and try it?
Certain pins have to be at the correct levels to program the chip.
Some other pins may be used by the SPI mode to talk to the flash chip.
If you are using an Arduino kit to program it does the kit work with another device?
