If you don’t have ECIDs please don’t go through this procedure as it can end up in screwing up your device OS. The ECIDs must be saved before up gradating to iOS 4.1 else you cannot downgrade after updating iOS 4.2.

Guide to Downgrade iOS 4.2 to iOS 4.1/iOS 4.0.1/ iOS 4.0.2 Firmware

  1. Download the required old ipsw firmware files to which you want to downgrade iOS 4.1/iOS 4.0.1/ iOS 4.2.1.
  2. Set up your device in DFU mode. For doing so, connect your device to computer and turn it off. Now Start iTunes and hold the Power + Hold button together for around 10 seconds. And now release the Power button but continue Home button pressed until your computer recognizes a new USB device. You will see iTunes logo and then “Connect to iTunes” will be displayed. Now you can release the Home button.
  3. Steps 4 and 5 should be followed by iPhone 3G or iPod touch 2G (non-MC model) users. If you have iPhone 4, iPad, iPhone 3GS, iPod touch 4G, 3G, 2G (MC Model) go directly to step 6.
  4. Go to the path “c:\windows\system32\drivers\etc\” in windows and open file “hosts” file in notepad. Mac users should go to path “/etc/” by going through “Go -> Go to Folder” from Finder and open the “hosts” file with text editor.
  5. Add the string “74.208.105.171 gs.apple.com” at the end of the file. This step enables to redirect requests for certificates for authenticity that iTunes will make to the Saurik server. Save the modified file.

Press and hold left “Alt” button on Mac (Left “Shift” button on Windows) on the keyboard and then click on “Restore” button in the iTunes and then release this button.
  7. A prompt will appear to select the old firmware file. Select the ipsw file to restore and click “Open”.

  9. Your iPhone will go into recovery mode and “connect to iTunes” message will appear on the screen.  Download TinyUmbrella on your computer and run it. Now click on “Kick Device Out of Recovery” button. Your iPhone will be restarted now.
