More than 200 million devices have already been updated to iOS 7 since it was released on September 18th. However, although fully supported, the iPhone 4 is struggling to run iOS 7 as it should be, mainly because of its lower hardware specs. If you have the iPhone 4 on iOS 7 and want to get off and go back to iOS 6 there may be a way to do it.

First off, you can only do this if you have saved your iOS 6 SHSH blobs – if you haven’t you are stuck with iOS 7 unfortunately. If you did save your blobs you can follow this guide. You must have Windows and this will only work on the iPhone 4
- You need to have iTunes 11.0.5 or lower so if you have updated to the latest v11.1.x you will have to uninstall it and reinstall an older version. When Apple updated iTunes they put a stop to restoring to custom firmwares. When you uninstall iTunes, be sure you remove absolutely everything related to it including Bonjour, Apple Software Update, and Apple Mobile Device.
- Restart your computer once you have uninstalled iTunes and then download v11.0.5. You may come up against an error regarding iTunes Music Library.xml – go to your iTunes Music file on your PC and delete the xml file.
- Download iFaith
- Download iOS 6.1.3 or 6.1.2 IPSW, depending on which version you saved your blobs for.
- Get your blobs from wherever you saved them. If they are on Cydia go into iFaith and click on “Show Available SHSH Caches on Server”
- Save your blobs to your PC
- Open iFaith and click on “Build”*signed*IPSW w/Blobs” to start the process of building your custom firmware
- Find your SHSH blobs and then choose the iOS 6.1.3/2 IPSW you downloaded earlier
- iFaith will use these to create your custom firmware
- Your device now needs to be put into pwned DFU – full instructions will appear on the iFaith screen, make sure you follow them exactly:
- Hold the Power and Home buttons down simultaneously for 10 seconds
- Let go of the Power button and continue to press down the Home button until your device screen goes blank
- Now you can open iTunes, select your iPhone 4, press the SHIFT key and click Restore iPhone in iTunes
- Point to your new custom IPSW and iTunes will restore your device back to iOS 6.1.2/3.
