Firmware

With iOS 15.0.1 having been available for a while, Apple stops signing iOS 15.0

Downgrade iOS 15

Apple released iOS & iPadOS 15.0.1 on October 1st, marking the first update to the company’s new mobile operating systems with bug fixes. Notably, this update resolved a problem with Unlock with Apple Watch not working correctly with the brand-new iPhone 13 lineup – an exceptionally valuable feature amid a raging pandemic in which mask-wearing has become a common sight.

Now that some time has passed since Apple released iOS & iPadOS 15.0.1, it’s no surprise to see that Apple is closing the signing window for the original iOS & iPadOS 15.0 firmware that launched to the general public just two weeks prior.

After releasing iOS 15 to the general public, Apple stops signing iOS 14.8

Downgrade iOS 15

A couple of Mondays ago, Apple officially released iOS & iPadOS 15 to the general public with a slew of new features for Apple’s mobile device lineup following an extensive beta period throughout the Summer months.

Perhaps unsurprisingly, Apple’s move to launch a new firmware version for its platforms has now been complemented with the unsigning of the previously current firmware — iOS & iPadOS 14.8.

One week after releasing iOS 14.8, Apple stops signing iOS 14.7.1

Apple released iOS & iPadOS 14.8 last Monday to patch serious vulnerabilities that could have been weaponized by hackers to run malicious code on others’ iPhones and iPads via iMessage. Most owners of these devices were advised to update without hesitation, except perhaps jailbreakers, given the gravity of what these vulnerabilities could have entailed.

Now that it’s been a week since that software update, it may come as no surprise that Apple has officially closed the signing window for iOS & iPadOS 14.7.1, the firmware that pre-dated iOS & iPadOS 14.8.

Apple no longer signing iOS 14.6 following the launch of iOS 14.7 (& iOS 14.7.1)

Following a lengthy beta testing period involving developers and volunteer participants, Apple officially released iOS & iPadOS 14.7 to the public last week with a long list of new features and improvements for iPhones and iPads alike. But no software update from Apple comes without the bitter aftertaste.

Just as Apple always does after releasing a major software update, the company closed the signing window for iOS & iPadOS 14.6, which makes it substantially more difficult for iPhone and iPad users to downgrade to the older firmware version if they’ve already updated the device(s) to iOS or iPadOS 14.7, or perhaps the newer yet iOS or iPadOS 14.7.1.
