How to Edit Windows & Mac HOSTS File to Downgrade iPhone Using iTunes?

Hi guys, I keep getting iTunes error 3194 every time I am trying to downgrade my iPhone 4 back to iOS 4.3.3 using iTunes and SHSH blobs. A friend told me that modifying iTunes HOSTS file will do the trick. So, any idea how to edit iTunes HOSTS file? Please help I am completely novice about iPhone jailbreaking. Thanks.

Hello Matthew, you are getting iTunes error 3194 because iTunes can’t access the iOS 4.3.3 SHSH blobs via Apple servers and editing / modifying iTunes HOSTS file will bypass this error. To do that, just simply follow the step by step guide posted below on how to direct iTunes to Saurik’s Cydia server.

How to Edit HOSTS File on Windows:

Step 1: Open Notepad or any text editing tool. Now, launch windows explorer or press Windows + E and navigate to C:WindowsSystem32driversetc and then in ETC directory open HOSTS file with Notepad.

Step 2: Then you have to add to the end of HOSTS file and then save it. 

How to Edit HOSTS File on Mac:

Step 1: Click on Go -> Go to Folder and then enter path /etc 

Step 2: Now you have to open HOSTS file via TextEdit and then add at the end of the file.

Well, there’s other option available to bypass iTunes error 3194 without editing iTunes HOSTS file. To do that, just simply follow this tutorial on how to create a signed iOS 4.3.3 SHSH blobs using iFaith SHSH Blobs Dumper v1.1. Once restored to iOS 4.3.3, you can refer on this guide on how to jailbreak iPhone using JailbreakMe 3.0.

      Make sure that you have admin access. Try running notepad as an administrator (Right-click > Run as Administrator). Hope this helps!!
