I saw the code 1015 for my iphone 3G after I restore my phone. Now I have trouble to turn on my phone. Can you please let me know what should i do?

iPhone 3G, iOS 4.2.7

    This is what Apple has to say.



    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 "unauthorized modification" the quote stedman posted is referring to is jailbreaking. If your iPhone has been jailbroken, then sorry but you're on your own. We cannot help with jailbroken iPhones in these forums.
