Troubles transfering firmware to Xbee radios

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


XBP24 means 802.15.4 modules (Series 1).

Series 2 modules supports ZigBee and ZNet.
Series 1 modules supports DigiMesh and 802.15.4.
