All who’ve upgraded their phone or tablet to iOS 12.3 can no longer backtrack to the previous version. This is because Apple has stopped signing iOS 12.2.

It’s not a reflection on that older version, but a standard action for the company to take. It always ends the installation of obsolescent versions shortly after a new one is introduced.

Anyone who upgrades an iPhone or iPad to iOS 12.2 can’t change their mind. Apple ceased digitally signing the previous version so it can’t be installed anymore.

This is normal. Apple always stops allowing people to downgrade a few weeks after a newer iOS version is released.

The most recent beta of iTunes reportedly won’t allow iPhone and iPad owners to reinstall an older iOS version. This is apparently the result of a bug rather than a change of policy by Apple.

It seems Apple will continue to allow users to downgrade to a previous version if a serious problem is found in a new one.

If you’ve moved to iOS 12.1, it’s no longer possible to go back to any previous version. Not that there’s much reason to.

As of today, you can’t install iOS 12.0.1 or earlier on an iPhone or iPad. This in-line with Apple’s standard practices.

If you hate iOS 8 -— whether because it runs like crap on your device, you miss your jailbreak, or because it’s significantly more buggy — you’ve previously had the option to downgrade back to iOS 7.1.2 if you wanted to.

But bad news. That ship has sailed. Apple has stopped signing iOS 7.1.2, making iOS 8 the only version of iOS that can be installed on any device capable of supporting it.

Do you hate iOS 8? Maybe you’re an iPhone 4s owner who made the mistake of believing Apple when they said that iOS 8 supported your device, or maybe you’re just a luddite who hates change!

Either way, you’re in luck: If you regret your upgrade, you’ve got a rare opportunity to turn the clock back. You can downgrade your device from iOS 8 to iOS 7.1.2, if you act fast.
