If you’ve an iPhone 4 and have saved SHSH blobs for iOS 6.1.3, then it
is possible to downgrade from iOS 7 to iOS 6.1.3 or earlier using
iFaith.We had briefly mentioned this a days back, but we finally managed to successfully downgrade from iOS 7 to iOS 6.1.3, so we thought of sharing the step-by-step instructions for those interested in downgrading.
Some important points before we proceed (please read them carefully before proceeding):
iFaith developed by iH8sn0w is only available for Windows.
You can downgrade only if you’ve iOS 6.1.3 SHSH blobs. This method should also work if you’ve SHSH blobs for iOS software updates released before iOS 6.1.3 such as iOS 6.1.2 etc.
This method currently works only on iPhone 4. It is not possible to downgrade any of the other iOS 7 compatible devices like the iPhone 5, iPhone 4s, iPad 4, iPad 3, iPad 2, iPad mini and iPod touch 5G.
If you’re still on iOS 6.1.3 then you should save the SHSH blobs using iFaith.
This process involves restoring your device with custom iOS firmware file, so restoring it from back up could be a time consuming process. So do this when you have time on your hand.
After you’ve downgraded to iOS 6.1.3, you will be able to restore from only an iOS 6.1.3 compatible backup. You won’t be able to restore from the iOS 7 backup, so it may be a good idea to take a backup of your photos and videos. There are several third-party solutions like Dropbox (iTunes link) and Google+ (iTunes link) that auto-upload your photo library to the cloud, so you can recover your life moments if something goes horribly wrong, and also to recover the photos and videos you had taken after upgrading to iOS 7.
Even though the iOS 7 backup may not be useful once you downgrade, it is a good idea to take a backup using iTunes or iCloud so you can recover the data if you realize, you’ve lost something critical during the downgrade process.
Follow these instructions to downgrade your iPhone 4 from iOS 7 to iOS 6.1.3.
1.Download iFaith from this link, and unzip the file.
2.Download iOS 6.1.3 firmware file for iPhone 4 from this link
