That is a 29-wire homebrew chip from the looks of the picture. The write enable line has been grounded, which is why it won't flash.
In the picture, there is a smaller wire that runs to several legs on the chip. The second pin from the top on the right side of the chip is pin 31. Isolate this pin from the jumper wire, then solder a wire to the pin and run it to the point on the LPC that already has a wire soldered to it (5v) making sure that both the previously soldered wire and your new wire stay attached to the LPC pin. You should then be able to flash it.
