Apple just last week released iOS & iPadOS 14.4 to the general public with new features, bug fixes, and niche improvements, and as you might come to expect from the Cupertino-based tech company after having released a software update, the previous iOS & iPadOS 14.3 firmware is no longer being signed.
Apple closed the iOS & iPadOS 14.3 signing window just this evening, a move on the company’s behalf that prevents iPhone, iPad, and iPod touch users from being able to downgrade their handset’s firmware from the newer iOS & iPadOS 14.4 release. This should come as no surprise to anyone, as Apple generally follows this rhythm of signing and un-signing after each software update it launches, no matter how large or how small.
Apple regularly releases software updates for the company’s many platforms, mobile and desktop alike. Interestingly, while most Apple’s software updates target either newer devices or upgrading the user experience of the company’s latest firmware iteration, a few heads turned when Apple released iOS 12.5.1 earlier this month to address a COVID-19 exposure notification bug that purportedly affected older iPhones.
Given that a software update was released, despite being for an older iteration of iOS, it should come as no surprise to anyone that Apple would soon close the signing window for what was previously the latest version of iOS 12. This happened Tuesday evening after Apple officially made the move to stop signing iOS 12.5, the predecessor of the newer iOS 12.5.1 update.
After officially launching iOS 14.3 to the public last month with new features and improvements, Apple has closed the signing window for iOS & iPadOS 14.2 & 14.2.1, a move that prevents affected iPhone and iPad owners from restoring their handset’s firmware version to anything but the current iOS & iPadOS 14.3 release.
In addition to iOS & iPadOS 14.2 & 14.2.1, the company has officially started unsigning iOS 12.4.9, which prevents older handsets that are incapable of being upgraded to iOS or iPadOS 13 from downgrading from the newer iOS 12.5 release.
First off, this guide is only necessary for 64-bit devices which are currently jailbroken on old firmwares, such as iOS 9 and some versions of iOS 10. The jailbreaks for those firmwares did not always include a way to set a generator for use with futurerestore, and nonceEnabler provides that ability. Nearly all newer jailbreaks provide their own simpler ways of setting a generator, and they do not need to use nonceEnabler, nor this guide. If your device is not currently jailbroken on an old firmware such as the ones mentioned in this guide, and/or has its own method of setting a generator, refer instead to our main futurerestore guides.
Apple unleashed iOS & iPadOS 14.2 to the general public last Thursday with a plethora of new Emojis, wallpapers, and other improvements. That said, no one should be astonished to learn that the company has stopped signing the older iOS & iPadOS 14.1 firmware this Thursday evening, just one week after the aforementioned release.
The unsigning of a particular version of firmware means that iPhone and iPad users can no longer officially downgrade to it via Finder or iTunes, and that’s because these platforms depend on ‘permission’ from Apple’s servers to continue the software restore on one of these devices. Third-party workarounds exist for the daring ones, of course.
In a rather unsurprising move, Apple closed the signing window for iOS & iPadOS 14.0.1 Tuesday evening, one full week after unleashing iOS & iPadOS 14.1 to the general public to introduce various bug fixes and improvements for the company’s user base.
By closing the signing window for this particular version of firmware, Apple has effectively built a firewall against those wanting to downgrade their iPhone or iPad’s firmware for one reason or another. But this shouldn’t take anyone by shock; after all, Apple loves being in control of its users and signaling what they can and can’t do with their devices. This is nothing new.
One week after officially releasing iOS & iPadOS 14.0 to the general public, Apple launched its first update for the new mobile operating system in the form of iOS & iPadOS 14.0.1 with minor usability bug fixes. As we approach one week after the release of the aforementioned update, it may not come as much of a surprise to most iPhone and iPad users that Apple has unsigned iOS 14.0 this evening.
When Apple unsigns a firmware, they are effectively preventing users from downgrading to that specific version of firmware. This means that anyone who updated to iOS 14.0.1 will not be able to go back to iOS 14.0 if they are, for any reason, unsatisfied with the latest update.
Apple officially released iOS and iPadOS 14 last Wednesday, bringing dozens of exciting new and notable features to iPhones and iPads alike. Now, one week after the aforementioned launch, Apple has stopped signing both iOS and iPadOS 13.7.
This is a particularly significant change because iOS and iPadOS 13.7 were the final versions of the 13-centric family to be released before last week’s public iOS and iPadOS 14 launch. That said, Apple has effectively broken the ability to downgrade iOS or iPadOS 14 back to iOS or iPadOS 13.
One full week has passed since Apple released iOS & iPadOS 13.7 to the general public, and like clockwork, the Cupertino-based tech company has pulled the plug on its signage of the older iOS & iPadOS 13.6.1 firmware for iPhones and iPads alike Tuesday evening.
The rather predictable move means that iPhone and iPad owners are now unable to downgrade the firmware they run on their handset of choice after upgrading to the newer iOS or iPadOS 13.7 release.
Apple stopped signing iOS & iPadOS 13.6 Wednesday evening, a predictable move on the Cupertino-based company’s part that is known to prevent users of these particular devices from downgrading from the newer iOS & iPadOS 13.6.1 firmware that was released to the general public one week ago to address a ‘green tint’ issue exhibited by some OLED displays, among other things.
We say predictable because Apple follows this trend like clockwork every time the company releases a new version of iOS & iPadOS, but we digress…
Apple stopped signing iOS & iPadOS 13.5.1 Wednesday evening, a move on the company’s part that effectively prevents iPhone and iPad users from downgrading from the newer 13.6 release that was released to the general public exactly one week ago from today.
The company is notorious for preventing firmware downgrades because it doesn’t want users downgrading to versions that are vulnerable to exploits – whether those exploits are being used maliciously or for the sake of jailbreaking. Compelling users to upgrade to newer firmware when restoring also buffs Apple’s new firmware adoption statistics that the company frequently enjoys flaunting at Keynote presentations.
Apple unsigned iOS & iPadOS 13.5 on Monday in a move intended to prevent downgrades to a publicly available jailbreakable firmware version. Hacker and unc0ver lead developer Pwn20wnd quickly responded to the act this week by releasing unc0ver v5.2.0 with support for iOS & iPadOS 13.5.5 beta 1, providing jailbreak hopefuls with a second chance to upgrade to jailbreakable firmware.
But as it would seem, this was a short-lived hoorah. Apple appears to have stopped signing iOS & iPadOS 13.5.5 beta 1 as of last night, effectively and once again preventing iPhone and iPad users from installing a jailbreakable firmware for the second time in the same week.
