The Iphone Could Not Be Restored An Unknown Error Occurred 29
34, 36, 37, 40These errors typically occur when security software interferes with the restore and update process. FollowTroubleshooting security software issues to resolve this issue. In rare cases, these errors may be a hardware issue. If the errors persist on another computer, the device may need service.Also, check your hosts file to verify that it's not blocking iTunes from communicating with the update server. See iTunes: Advanced iTunes Store troubleshooting--follow steps under the heading Blocked by configuration (Mac OS X / Windows) > Rebuild network information > Mac OS X > The hosts file may also be blocking the iTunes Store. If you have software used to perform unauthorized modifications to the iOS device, uninstall this software prior to editing the hosts file to prevent that software from automatically modifying the hosts file again on restart.

Error 3194, Error 21 and Error 1013 I finally found a few ways to resolve this after searching on Apple's support page and other sites. I also came to the conclusion that the error 3194 in iTunes and the other errors are quite common and luckily quite simple to isolate to then resolve. Now the key here is isolate. Try one step at the time, don't overdo it. Note for Jailbreak and Firmware Downgrade. If your issue is unrelated to Jailbreak or Downgrading a device then skip this section and move on to the next one. This guide is not intended for downgrading or Jailbreaking, and while the info provided may still be useful it may not apply to your case. So unless you're trying to restore your iOS device to the latest version of iOS this guide may not be for you. Comments regarding this error while jailbreaking or using a software version other than the latest one will be ignored. What causes the error? The error 3194 happens when iTunes tries to validate the downloaded restore file (.ipsw) and is unable to reach Apple's validation servers. The reason is usually something blocking the connection. Other causes are to try to use a firmware version that Apple is no longer signing ie. 5.1.1. So basically you can't use an older firmware unless you work around the security that Apple has put in place. This article does not cover bypassing these security restrictions. Common causes are: Firewall (try to disable it and attempt restoring again) Antivirus (try to disable it and attempt restoring again) Hosts file blocking access to the validation server. (keep reading for help with these) Stubborn computer (By all means try a different machine if you've tried everything here). Try this on a Mac (iTunes works almost flawlessly when used on a Mac) In OS X the error shows as: "The iPhone "name" could not be updated. This device isn't eligible for the requested build." OR "The iPhone "name" could not be restored. This device isn't eligible for the requested build." In Windows the error is even less descriptive: "The iPhone "iPhone" could not be restored. An unknown error occurred (3194). Fixing error 3194 in iTunes Quit iTunes Download TinyUmbrella.
