This is my only telephone and now it's locked up.
Anyone have any idea what the **** error -1 is? and how do I get my phone back online?
iPhone 4, iOS 4.2
Perhaps try the Error 1 or -1 advice from the following document:
iTunes: Specific update-and-restore error messages and advanced troubleshooting
Hi, I have error (-10), which is not on the list under the url you provided. How shall I fix it?
I got the same (-10) error. I think it means the iphone was disconnected during the restoration. In my case it was being disconnected when my computer went into sleep mode. I changed my computer settings to not go into sleep mode and it stayed connected and restored correctly. Give it a try.
"An error occurred while restoring this iPhone (-1)" NOW WHAT?
