iPhone 3G Error 1015 iTune Error not able restore the iPhone each time get this error 1015

Hello BOSSusany,

It sounds like you are getting this error code 1015 when you try to restore the phone. I recommend this info from the article named:

Resolve specific iTunes update and restore errors

http://support.apple.com/kb/ts3694#1015

Error 1015 might happen after making unauthorized modifications to iOS, also called "jailbreaking."

Use recovery mode to restore your device

Related errors: 1015, “The required resource can't be found.”

You might see these error messages if your device has a beta version of iOS or if you're installing an older version of iOS (downgrading). Use recovery mode to restore your device to the latest version of iOS.

Quit virtualization software

Quit any virtualization software (such as Parallels or VMware) that’s running on your Mac. Then use the latest version of iTunes to restore your device.

Thank you for using Apple Support Communities.

All the best,
