Apple Stops Signing iOS 16.0.3, Downgrading From iOS 16.1 No Longer Possible

by

Following the launch of iOS 16.1 on October 24, Apple has stopped signing iOS 16.0.3, the previously available version of iOS that launched on October 10. As iOS 16.0.3 is no longer being signed, it is no longer possible to downgrade to that version of iOS after installing iOS 16.1.

iOS 16
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, so it is not unusual that iOS 16.0.3 is no longer being signed.

iOS 16.0.3 was a smaller bug fix update that addressed bugs that were plaguing the iPhone 14 and iPhone 14 Pro models.

The iOS 16.1 update that replaced it is much larger in scale, introducing iCloud Shared Photo Library, Live Activities for the Lock Screen and Dynamic Island, support for the Matter smart home standard, Clean Energy Charging, and more, with details available in our iOS 16.1 guide.

iOS 16.1 is a buggy mess. I wish I had stayed on 15.7 and instead updated to 15.7.1.

I learned my lesson: In the future, I will only consider updating to a new iOS or macOS when the x.2 version is released.

That practice should be illegal. My government agency doesn't OK new IOS versions for months and if a phone gets upgraded by mistake we can't go back to an older version. The phone is temporarily bricked.
If your government's IT doesn't allow new iOS versions until they give approval then they should manage the devices in a way that won't allow individual users to upgrade by themselves.

How does it get upgraded by mistake? My company uses a profile that blocks upgrades and only allows the last accepted iOS version to be installed. I would have to manually delete the profile or do a complete wipe and install the newest OS. And an upgraded OS shouldn’t “brick” the phone, you just can’t use your company’s software on it until IT catches up.

Obviously an incompetent IT department within that agency. They make mobile device management software for just such a reason, preventing users from doing things. We need less government overreach in making things illegal thanks.

Yeah I no longer upgrade until at least the holidays. The new features are so minor these days it isn't worth the buggy mess.

iOS really should go to a n every other year upgrade for software.
