Xbee module doesnt respond

I updated the firmware on 2 xbee series 1 modules and one of them stopped working properly. When I connect to it from the xctu, it’s unable to connect. If I enable API it connects but doesn’t see the firmware version and if i try to read or write to it the process fails. When the module is plugged into the xbib board the 3 RSSI leds are lit, the power led is half-lit and the serial data in led keeps flashing. What is the problem? Thanks.

Well in case someone has the same problem, I fixed it, it only worked when i read the parameters from the working module and wrote them unto the nonworking one, and only then it allowed me to write default params over it.
