As You can see from Software log, phone's modem part is damaged:
This can be Software (modem firmware or EFS is damaged, or You have written unsuitable firmware) or HW problem.

You should re-flash the device with different firmwares one by one and check, whether modem is correct (not Unknown). And only then (when phone's modem part will be correct) perform necessary operation.
