Not able to connect to Network using C-115 devices.

Hi, Finally i am able to compile the GSM Stack code and flash into the Motorol Device C-115. i can see the "layer1.bin" on the display, but my device is not latched on to the N/W. - When i ran the HOST software of Mobile. i can see that SIM reader code is not working, and i can see the IMEI is hardcoded to "0000000000000000". - i captured the response of FBSB(Frequency and Time synchronization Burst), the result is comming as "255". can any one please help me how to resolve these issues so that i can latch on to the N/W. regards, nageswara reddy.
