If 1 judges that according to the phenomenon of the failure of mobile phone the radio-frequency (RF) calibration parameter may be damaged, then the instrument by special use detects the radio frequency calibration parameter and carries out radio-frequency (RF) calibration, the radio-frequency (RF) calibration parameter after the record calibration again.
2, mobile phone is carried out software and hardware and detect, be damaged then adorn execution in step 3 behind the App executable file again if detect the App executable file, if the App executable file is not damaged, direct execution in step 3 then.
3, cell phone rebuild file system stores new radio-frequency (RF) calibration parameter in the file system area into document form with other key parameters.
4, when needed, the radio-frequency (RF) calibration parameter is submitted to corresponding radio frequency processing module.
Like this, could recover the radio-frequency (RF) calibration parameter, thereby make mobile phone realize normal wireless signal transmission-receiving function.
