    Try to restore your device with iTunes. If that doesn't work you will have to get it serviced.

     

    Error 1015: This error is typically caused by attempts to downgrade the iPhone, iPad, or iPod touch's software. This can occur when you attempt to restore using an older .ipsw file. Downgrading to a previous version is not supported. To resolve this issue, attempt to restore with the latest iPhone, iPad, or iPod touch software available from Apple. This error can also occur when an unauthorized modification of the iOS has occurred and you are now trying to restore to an authorized, default state.  Very rarely this error is caused by a hardware issue and requires service.

    Force your phone in to DFU mode and then restore (if iTunes allows you to).

    Search in Google "Force iPhone in to DFU mode" and follow the instructions precisely.

     

    Refrain from making unauthorized modification in your iPhone after a successful restore.
