Then, it goes https://www.youtube.com/watch?v=_jV6su4qJEw to the Connect to iTunes screen and when I connect it to iTunes it tells me that I need to restore the phone.

I had jailbroken and unlocked one of my iPhones. To prepare for WWDC 2012 starting next week, I decided to restore my iPhone to be in the good books of Apple and not having to carry around http://survivalguide4idiots.com/fix-iphone-restore-error-21-how-to.html a jailbroken iPhone. However, when I tried to upgrade my iPhone to the latest version http://anditsfixed.blogspot.com/2012/10/solved-itunes-error-3194-error-21-and.html of iOS 5.1.1, I was greeted with error 21. Error 21 goes like this " The iPhone could not be restored. An unknown error occurred (21)." Go to Apple Support forum to look for a resolution of error 21 and you'd probably find one of the most generic and useless information out there. Have a look yourself here. If you're also error 21 facing error 21, in all likelyhood, the phone was either jailbroken or physically damaged. In the latter case, you can get a replacement from Apple. US$149 for a 3Gs or 4 (or 3G, but that wouldn't be worth it at this point), US$199 for a 4S. If it was jailbroken, they won't touch it. So, what do you do? Don't worry, we're here! Some of the scenarios in which "An unknown error occurred (21)" shows up: Upgrading to an unknown error a newer version of iOS on your iPhone Restoring your iPhone There are 2 easy solutions to resolve error 21. Use either one, which best suits you. You will find plenty of solutions on the internet, do not try one which seems risky, else your iPhone will turn into a brick in no time! How to Fix iPhone Restore Error 21 - Option # 1 Easiest option is to upgrade or restore using a computer, which you've not used before or belongs to someone else. Bottom line is that you need to use a computer (Mac or PC) other than the one, which gave you error 21. If you have only one computer, you will have to edit your host file (option # 2) because it has an entry, which is preventing upgrade or restore of your iPhone and resulting in error 21. How to Fix iPhone Restore Error 21 - Option # 2 If you do not want or have another computer to resolve iTunes error 21, you can edit your host file. Windows users - Navigate to C:WindowsSystem32driversetc and locate “hosts” file. Mac users - Navigate to privateetc and open the hosts file. Next, you want to back up the hosts file somewhere and delete everything under the 127.******* local host line and save it. Restart your iTunes in case of Mac and restart your computer in ca
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.
