How To Downgrade iOS 7 To iOS 6 Using iFaith
There have been a ton of people who have updated their iPhone, iPod Touch or iPad to iOS 7 and wished they could have downgraded back to iOS 6. But unfortunately it is impossible right? Well this may not be the case for iPhone 4 owners who managed to save their SHSH blobs on iOS 6, specifically on iOS 6.1.3 or 6.1.2.
Due to the fact that a bootrom exploit is present on the iPhone 4 that leaves it Jailbroken for life, it also means that it can be downgraded for life as long as you have saved SHSH blobs. So if you have an iPhone 4 that is running any variant of iOS 7 and you would like to go back to iOS 6.1.3 or 6.1.2 (or any iOS 6 firmware you have saved SHSH blobs for) you will be glad to know it is indeed possible and in this tutorial we will show you how to downgrade.
Unfortunately this leaves a lot of people in the dark, however, but that is the reality of the situation. Only iPhone 4 owners with saved SHSH blobs with a Windows computer will be able to take advantage of this specific downgrade.
How To Downgrade iOS 7 To iOS 6
Step 1) - The first thing you will need to do is ensure you are running iTunes 11.0.5 or below. If you are on a newer version of iTunes like 11.1.x then you will need to uninstall it from your computer and re-install an older version. This is because newer versions of iTunes actually kill the ability to restore to custom firmware files. One last thing to keep in mind is when uninstalling make sure you remove all traces, including services like Apple Mobile Device, Apple Software Update and Bonjour.
Once you uninstall iTunes and all of the related services, restart your computer and then download iTunes 11.0.5 from here. When it downloads install it. If you encounter an error that has to do with “iTunes Music Library.xml”, head over to your iTunes Music folder and delete said file.
Step 2) - Now it is time to grab the latest version of iFaith and of course either the iOS 6.1.3 firmware or 6.1.2 firmware from the iJailbreak Downloads Section. Lastly you will need to acquire your SHSH blobs from wherever you saved them locally. Those who saved them on Cydia will need to make use of the “Show Available SHSH Caches on Server” option in iFaith to save them on your desktop now.
Step 3) - Ensure iFaith is up and running if it isn’t already and click the ”*signed* IPSW w / Blobs”. This will begin the custom firmware creation process where you will need to select your SHSH blobs and then iFaith will work its magic and create a downgradable iOS 6 firmware file for your iPhone 4.
Step 4) - Once it has been created follow the on-screen instructions for putting your device into Pwned DFU mode. When your iPhone 4 enters Pwned DFU mode launch iTunes, select your iPhone, Shift click the restore button and select the custom firmware iFaith created.
After the restore is complete you will have successfully downgraded your iPhone 4 from iOS 7 to iOS 6.1.3 or 6.1.2.
