sharp gx10 problem

hi to all.......
i unlocked (an already unlocked phone just to check my cable). After this, the phone's reception became less.
Someone told me that the some softwares use brute force unlocking method and resets all the eeprom and rx tx values and we need to calibrate these values. But there is no software for this purpose.

Please help if there is any solution for this problem?

thanks in advance
