sorry to say about this.after flashing and thosw process complit no sim detected..
this is hardware or software isue....plz guide me.

As shown in you log, phone has null IMEI, that means Calibration data was corrupt already.

This process reads QCN from phone and writes back in last step, so if you QCN was already corrupt, then that corrupt QCN was written back.

You can try writing working QCN.
