    Hi faryaz the next step i would recommend is a reset all settings

     

    settings > general > reset . reset all settings

     

    This will not delete any of your data but it will put all of your settings back to factory settings ( i.e. ringtones, backgrounds, etc...)

     

    test this out and let me know how it works

     

    Its best ot do all the software troubleshooting before jumping to hardware replacments

    If you have tried a restore as new expecially in DFU mode you have done all the software troubleshooting neccesary this narrows it down into a hardware issue.

     

    Apple does not recommend doing any repairs on your own because it will void your warranty however

     

    You would be looking into repairing your Signal Antenna

     

    Before doing this repair i would suggest contacting your carrier and having them reset your cellular network just in case

     

    Good luck

     

    Let me know how it goes

    If the Antenna has already been replaced that would leave the only other option as being an issue with your carrier. I would suggest contacting them and telling them all the troubleshooting you have completed and see if there is a problem on their end.

    There is a possibility the logic board could have a short in that but that would be hard to determine without doing the actual repair. Even though the price on repair for the antenna was fairly cheap you will find the price for a logic board repair is quite a bit more. I would bring it back into your repair shop and see what they recommend at this point.
