Apple Stops Signing iOS 17.1, Preventing Downgrading

Apple today stopped signing iOS 17.1, a move that will prevent iPhone users from downgrading to that version of iOS. Apple is no longer signing iOS 17.1 following the release of iOS 17.1.1, which came out on November 7.

iOS 17
It is not unusual that iOS 17.1 is no longer being signed. Apple routinely stops signing older versions of iOS after new releases in order to encourage customers to keep their operating systems up to date and to prevent users from downgrading to older, less secure versions of the software.

iOS 17.1.1 is the current version of iOS 17 that is available to the public. It introduced several bug fixes, addressing a weather widget bug and fixing issue that could cause NFC not to work in iPhone models charged with a BMW wireless charger.

Apple is also testing iOS 17.2, an update that is expected to come out in December.

Can't wait for the end of this nonsense. If there's one thing the EU needs to do is let users have control over their devices.

Why can't people downgrade to 16.7.2 if they want to, Apple? It receives security updates!

It seems to me that almost every time Apple wants everyone on its latest firmware, it announces some kind of zero-day threat. Not every time but often enough to make me wonder.
