I have a bricked Xbee 1... Unfortunately I tried to use the FTDI friend (through my PC) connected to the Xbee adapter with X-CTU to upgrade my firmware to 10ED. It failed with the error checksum failed, can't write parameters. Now no matter what I do, the thing is bricked. I've looked at Digi's instructions for how to unbrick it but they don't work. Not sure what to do... Can I send it back for a replacement? I will never update firmware again.
