Now click the write button on X-CTU. It should give you an error message, but do not click out of this one. Flip over the XBee Explorer. Now, take your jumper wire and touch RST (not RTS) to the GND pin of the Explorer for about a second. Take away the jumper wire. The error message should go away! It will start to load the firmware on. Once the error message comes up again, repeat the above step again. Now your XBee has been restored!
