Technically speaking, if the board is still in working order, you cannot brick the board. You may have blown a pin by connecting it to 3.3V direct instead of through a large pull up resistor especially if the pin was acting as an output on power up The flashing LED indicates that you popped the processor..
You will need to request an RMA to get it fixed. http://www.elinux.org/Beagleboard:BeagleBoneBlack#RMA_Support Gerald.
