iOS 7’s jailbreak is not available at the moment, and we don’t think that it’ll be happening anytime soon. However, many people have updated their iPhone, iPod Touch or iPad to iOS 7 and wished that they could downgrade back to iOS 6. While unfortunately that’s not possible on the new phones, if you’ve thinking to downgrade to iOS 6 on your iPhone 4, then you’re in luck. The only condition is that you should have saved your SHSH blobs on iOS 6, specifically on iOS 6.1.3 or 6.1.2.
Tutorial to downgrade to iOS 6.1.3 or 6.1.2 or any other iOS 6 variant
If you haven’t saved your SHSH blobs in the past, then you’re stuck with iOS 7. So if you have an iPhone 4, and are running iOS 7, then follow the below tutorial to downgrade to iOS 6.1.3 or 6.1.2 (or any other iOS 6 variant that you’ve saved SHSH blobs for).
Note: This tutorial only applies to iPhone 4, and users running on Windows.
Step 1: Firstly, you’ll need to be running iTunes 11.0.5 or below, and if you’re on latest version of iTunes, then you’ll need to uninstall it first. This is because newer version of iTunes doesn’t allow you to restore from a custom firmware file. When uninstalling, ensure that you remove all traces and services like the Apple Mobile Device, Apple Software Update and Bonjour.
Once you’ve uninstalled iTunes and all of its related services, restart your computer and download iTunes 11.0.5 from here. If you encounter any error during this process related to “iTunes Music Library.xml” then head over to the iTunes music folder and delete this file.
Step 2: Now it’s time to download the latest version of iFaith, and also the iOS 6.1.3 firmware or 6.1.2 firmware, depending on which firmware you’ve saved SHSH blobs for. If you’ve saved them on Cydia, then you can make use of “Show Available SHSH Caches on Server” option in iFaith and then save it to your Desktop.
Step 3: Launch iFaith and click on “Build “*signed* IPSW w / Blobs.” This will begin the custom firmware creation process, and when prompted, select your SHSH blobs. iFaith will then create a downgradable iOS 6 firmware file for your iPhone 4.
Step 4: Once the firmware file has been created, follow the on-screen instructions for putting your device into Pwned DFU mode. When entered into this mode, launch iTunes, select your iPhone and hold down the left SHIFT key and click on Restore iPhone. Browse to the custom firmware file created by iFaith.
Once the restore process is complete, you have successfully downgraded your iPhone 4 from iOS 7 to iOS 6.1.x.
