I have : A MacBook pro 13.3" 2011 model (OSX Lion)
iPhone 4S 16GB Black - On T-Mobile (EE)
The latest version of iTunes
Hi
I had tried restoring my iPhone 4S 16GB today because of a signal issue.
When I had clicked all the settings for restoring, I waited for it to restore.
I get an error message quoting "(-1)" Shown Below
I press the "More Information" button, which takes me to this link - "http://support.apple.com/kb/TS1275?viewlocale=en_US&locale=en_UK"
I read all the troubleshooting instructions and none of them have worked.
I have checked out other forums and they haven't been of any use!
Thanks
Ol'

This may indicate a hardware issue with your device. Follow Troubleshooting security software issues, and restore your device on a different known-good computer. If the errors persist on another computer, the device may need service.

Did you try to put into Safe Mode and then restore it?
