Apple Stops Signing iOS 13.4.1 Following Release of iOS 13.5

by

IPSWFollowing the release of iOS 13.5 on May 20, Apple has stopped signing iOS 13.4.1, which means downgrading to that version of iOS is no longer possible.

iOS 13.4.1 was a minor update that addressed a bug that prevented devices running iOS 13.4 from participating in FaceTime calls with devices running iOS 9.3.6 and earlier.

Apple routinely stops signing older versions of software updates after new releases come out in order to encourage customers to keep their operating systems up to date.

iOS 13.5 is the current publicly available version of iOS, with the update introducing the Exposure Notification API, faster passcode entry when wearing a mask, changes to Group ‌FaceTime‌, and more.

Apple has also stopped signing iOS 12.4.6 for older devices.

There could soon be another iOS update released as a jailbreaking tool that works with all devices running iOS 11 to iOS 13.5 was released on Sunday.

The only time I wanted to downgrade was when I wanted to keep one iPad dedicated for 32-bit apps that had a 12.9 inch screen. I have not found replacements for some games that I really enjoyed including on Android. As a workaround, I found an iPad 2 but it was a standard issue 16 GB model so I can't have everything on it. I have an old copy of iTunes and I keep checking for updates. It is disappointing that great app ideas never get updated to run on today's iOS.

I have always hated that I can't load an old version of IOS. A few years ago, I upgraded to a newer version of IOS but a month later, after Apple stopped signing that old version, I discovered the newer version would no longer work with some of my Bluetooth devices. It was close to 6 months before a subsequent version fixed the problem. If I could have loaded the previous version, I could have waited until the issue was resolved.

That's why I always save the SHSH2-blobs for all my devices when a new update comes out. With this method I could downgrade all the way back to iOS 7 if I want to...


How do you do that then? So if I went to 13.5 how do I go back down (I know I cant now)?
1) go to https://tsssaver.1conan.com/
2) save the SHSH2-blobs every time a new version appears (they are a kind of cryptographic signature specific for your device and iOS version)
3) when you want to downgrade download the saved blobs and download the ipsw for the desired iOS version
4) sign the ipsw using the downloaded SHSH2-blobs
5) drag the signed ipsw into iTunes to downgrade
