Before the actual release of iOS 5 final version, Apple has seeded a gold master version of iOS 5 to the developers for checking the application compatibility and for some other testing purpose. Many of you have already updated the GM release, if you are not satisfied with it because of some compatibility issues and unavailability of certain applications, we will help you to downgrade it to the earlier versions like 4.3.5, 4.3.4, 4.3.3, 4.3.2 in the blink of an eye. If you haven’t yet upgraded to the latest release we advice you to create a backup copy of your SHSH blobs.
- On the first step you must have downloaded the IPSW files of iOS version you are going to downgrade to. Earlier iOS versions can be downloaded from the links that are given below.
- After downloading the required IPSW files, you need to put your Apple device into DFU mode. If you are not yet aware of how to do it, here are the steps for putting your device into DFU mode. Once the device has successfully entered into DFU mode, your screen should be blank.
- Next thing you have to do is to edit a file named ‘hosts’. Go to Windows->System32->drivers->etc ( for Windows) and /etc/ (for Mac). Open it using any text editing application and add the following address.
- After saving hosts, launch iTunes. Your iOS device will be listed on its sidebar, select it. Hold the ‘shift’ key (For Windows. If you are running Mac OS, hold the ‘alt’ key) and click on the ‘Restore’ button. Browse to the IPSW files of iOS version you are going to downgrade to. That’s all about downgrading.
- There may be a chance to occur a ’1013′ error during the process. TinyUmbrella will serve you to get rid of that error. You can download TinyUmbrella from here.
