Restoring Problems

A friend of mine recently updated her iPhone 3GS to what I think was the IOS 4.2.1 software through itunes.

The iPhone software prior to the update was uncracked and from what I could tell was perfectly fine.


The problem we are having is that when we try restore we get the following image

I follow the more information link and click on the error code (1015)

after clicking that I find this from the link

So I have two questions.

1> Why is this happening?

2> How do I fix the phone and restore it for my friend?

iPod touch (4th generation), iOS 5.0.1

iTunes: Specific update-and-restore error messages and advanced troubleshooting

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.
