How to Downgrade iOS 4.3.1 to 4.3, 4.2.1, 4.1 on iPhone 4, 3GS, iPad 2, iPad, iPod touch [Guide]

Apple today has released iOS 4.3.1 for iPhone 4, 3GS, iPad 2, iPad, and iPod touch 4G/3G. If you upgraded to iOS 4.3.1, and now you want to downgrade back to iOS 4.3, iOS 4.2.1 or 4.1, simply follow the instructions posted below to downgrade iOS 4.3.1 on iPhone 4, 3GS, iPod touch, iPad 2 and iPad 1 to iOS 4.3, iOS 4.2.1, 4.1, 4.0.x.

Step 1: Download the required old ipsw firmware files. (Download links: iOS 4.3, iOS 4.2.1, iOS 4.1, iOS 4.0.2, iOS 4.0.1)

Step 2: Put your device into DFU mode (not recovery mode).

Connect your iOS device to your computer.
Turn it off.
Start iTunes.
Hold Power and Home buttons together for 10 seconds or so.
Release Power button but keep holding the Home button until your computer recognizes a new USB device.
iTunes will now recognize your iPhone, iPad or iPod touch.
Note: Your iPhone, iPad or iPod touch screen at this time should be blank (black in color), if not, then you are most likely in Recovery Mode, not DFU mode.

Step 3: Start iTunes, click on your iOS device icon from the sidebar in iTunes. Now press and hold left “alt” (option) button on Mac, or Left “Shift” button if you are on Windows on the keyboard and then click on “Restore” (Not “Update” or “Check for Update”) button in the iTunes and then release this button.



This will make iTunes prompt you to select the location for your iOS 4.3, iOS 4.2.1 or 4.1 firmware file. Select the desired ipsw file and click on “Open” to restore your iOS device.

Now sit back and enjoy as iTunes does the rest for you. This will involve a series of automated steps. Be patient at this stage and don’t do anything silly. Just wait while iTunes installs the requested firmware on your iOS device. Your device screen at this point will be showing a progress bar indicating installation progress. Once done, it will reboot automatically.

Now in some cases while restoring to iOS 4.3, iOS 4.2.1 or 4.1, iTunes might throw 1013 error at you as shown in the screenshot below. This is normal, just ignore this error as the firmware has already been successfully installed on the device.



Incase of the above mentioned error, your iPhone, iPad or iPod touch will be stuck in Recovery Mode, showing that “Connect to iTunes” screen.



To exit your device from Recovery Mode, download this program called TinyUmbrella (Windows/Mac). Run it and the click on “Exit Recovery” button. Your device will now restart normally.
