1 of 4 phones not loading

Hi, I've got 4 C115 phones (all same firmware). One is not loading and reporting the ftmtool error. The others are loading fine. Could this be caused by a blown RX input on the chip? Or could there other reasons why it does not work. I tried both an FTDI cable and a buspirate.
