Unable to communicate with modem (Xbee XB24-Z7WIT-004)

I am stumped on this one! I am trying to configure a couple of new Xbee S2 (Xbee XB24-Z7WIT-004) using X-CTU; I always get “Unable to communicate with modem” error.

I have tried everything suggest on this forum (different baud rate, with API, without API…) with no luck. I followed the recovery instructions in the knowledge center:

When I attempt to update the firmware, it writes OK and stops at the point where it says “Waiting for the device to reset”. It doesn’t react to the reset button being pushed.

I can get to the boot loader menu from the terminal.

I even tested the explorer by removing the Xbee module and shorting Tx Rx, I can see data getting echoed.

Anything that I missed?
