I bought an iphone 5c from Craigslist. Working fine until I tried restoring it. Been trying constantly for the past 3 days to figure out what this means. I regret ever attempting to try to restore this phone. This is my last hope. I tried... -using a different computer -using different USB ports -Turning the phone off and on -Turning firewall off I'm not really familiar with iphone or apple. This is actually my first device ever. If anyone is aware of this error or a solution to it, please let me know. Otherwise, I give up.
