Apple Stops Signing iOS 13.3.1 Following Release of iOS 13.4

by

IPSWFollowing the release of iOS 13.4 on March 24, Apple has stopped signing iOS 13.3.1, which means downgrading to that version of iOS is no longer possible.

iOS 13.3.1 was a minor update that added a toggle for disabling the U1 chip in Apple's iPhone 11, 11 Pro, and 11 Pro Max.

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 13.4 is the current publicly available version of iOS, with the update bringing a new Mail toolbar, iCloud Folder Sharing, new Memoji stickers, trackpad support on iPad, and more.

Developers can also download iOS 13.4.5, an upcoming update with bug fixes and a new option to share Apple Music songs on Instagram Stories.

Still happily on iOS 12.4.1. Every time I think of upgrading I read all kinds of horror stories with email and crashing and the such. Maybe iOS 14 will be better. Not likely though. I think each iteration is progressively getting worse. iOS 8 was my favorite then iOS 10.

I have always hated Apple's pathetic "no downgrade" policy. There are countless stories of people upgrading then discovering weeks later the upgrade broke something. I don't care what Apple's reasons are, this is and has been a terrible policy for consumers. :mad:

They stopped signing 13.3.1 and I'm still on 12.4 lol. I get much better performance on my 8 Plus than 13.4.

The fact that Apple refuses to let people downgrade their iOS versions will always be one of the many reasons I can never consider iOS devices to be "real" computers

Agreed. They broke playing homemade mp4's so now I can't watch them anymore on my iPad. Only Apple purchased movies work now. Wish I could down downgrade because I gained nothing useful but lost a major function by upgrading.
