Troubles transfering firmware to Xbee radios

Hello;
I am a user of the XBee modules. I’ve had problems in the transfer of
firmware to the modems.
My radios are XBP24. Which list of firmware is incompatible with these radios?
How I can solve these problems? Now my radios don’t respond to any computer messages, I can’t read / write to Xbee’s.
I have reviewed some solutions on the Internet, as do a reset just when the error window appears, but I have not got any solution.
Thanks in advance
Anton

Hey Check out following video.

But always remember, that you are using correct modem types, function set and firmware version in the x-ctu software.

Hello;
Thanks for the quick response … I have reviewed the video but nothing … Perhaps the
problem is I do not use any interface board between the XBee and PC. I use an Arduino without microcontroller connecting via USB. To connect the Arduino and the Xbee, I use the pins:

3.3V (Arduino) -> VCC (XBee)
GND (Arduino) -> GND (XBee)
Reset (Arduino) -> RST (XBee)
Tx (Arduino) -> Din (XBee)
Rx (Arduino) -> Dout (XBee)

When it’s time to reset, I push the reset button on my Arduino … But nothing happens.
My radio is XBP24-Z7WIT-004rev H. …
With all this information … Any suggestions? I do not really know what to do, I’m confused …
Thank you very much
Anton
