    From Apple's Knowledge Base:

     

    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.

    ####

    The answer: Upgrade your iOS.

    Can't do it. Error 1015 is generally related to attempts to downgrade software. Usually makes the phone unusable, voids the warranty and won't let you get support from Apple or the communities here.
