There is no help you can get from this forum.

Error 1015 occurs when trying to restore a previously jailbroken phone or trying an unauthorized downgrade of the firmware or baseband.

You will have to search the internet for help with your problem. Keep in mind there may be no solution and that you may have permanently "bricked" your phone.

Best of luck.

In my case I have an Iphone 3G. My mum got it unlocked legally by the old provider and gave it to me. The phone worked fine with my SIM card but couldn't find any Wi-Fi networks (a common problem in 3G). I read here that the solution to this problem was restoring the phone to factory settings. So I did and now I have the error 1015 in a NON-jailbroken phone. What can I do?

you have to install something called recboot and press exit recovery after you have restored and it'll work!

Unlocked legallay and unlocked legitimately may be 2 very different things. If she took it to a shop, even one run by her old provider, and walked out with it "unlocked" it was NOT legitimately unlocked.

In some rare instances, error 1015 is an indication of a critical hardware failure and the phone will require service.

True, the shop guy might have used a jail breaking teechnique to unlock it

If it was a guy in a shop, That is ALL they could have done. Legitimate unlocking by a carrier is handled completely differently and can take anywhere from several days to several weeks depending on the carrier.

A request is made to the carrier to unlock and any required fees are paid. If approved, the carrier forwards the relevant information to Apple, who adds the phone to their database of unlocked devices. Apple then notifies the carrier who sends a text message to the end user telling them this is complete. The user must then insert a foreign SIM in the phone and plug it into iTunes, where they should get a message that the phone has been unlocked.

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.
