Here, we’ll show you how to find your serial number, firmware version, and available space on Kindle Paperwhite.
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 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.
Apple this evening stopped signing iOS & iPadOS 13.5, a move on the Cupertino-based company’s behalf that essentially prevents iPhone and iPad users from installing this particular version of its firmware whether downgrading from a newer version of the mobile operating system or upgrading from an earlier version.
The move comes approximately one week after Apple released iOS & iPadOS 13.5.1 to the general public specifically with the intention of patching the 0-day kernel vulnerability that Pwn20wnd implemented into the unc0ver jailbreak to add support for iOS & iPadOS 13.5, the latest version of Apple’s mobile operating system at the time.
Apple on Monday released iOS and iPadOS 13.5.1 to the general public for the sole purpose of patching the new exploit in the unc0ver v5.0.0+ jailbreak tool, and as you might come to expect, Apple will soon unsign the jailbreakable iOS 13.5 firmware.
It usually takes the Cupertino-based company a week or two after a new firmware release before it stops signing an older version of iOS or iPadOS, but in recent memory, just one week has been a lot more common. By doing this, Apple can leave its user base with no option of downgrading or upgrading back to iOS or iPadOS 13.5, effectively preventing users from jailbreaking.
Apple is no longer signing iOS or iPadOS 13.4.1 as of this evening, a move that prevents iPhone and iPad users from downgrading from the iOS and iPadOS 13.5 software updates that the Cupertino-based tech giant released to the general public just last week.
Downgrading iOS device firmware isn’t a common necessity, but it can be necessary if or when Apple releases a software update that introduces bugs or instability to its devices. This isn’t a particularly common thing to happen, but it did transpire last October when iOS 13.2 was found to be ‘too aggressive’ with backgrounding restrictions, compelling many users to downgrade until a software update could be released to fix the issue.
Apple on Wednesday stopped signing iOS and iPadOS 13.4, a move on the Cupertino-based company’s part that prevents its users from intentionally downgrading their handset’s firmware version to anything besides the latest release.
Notably, iOS and iPadOS 13.4.1 were only just released last week. Apple typically waits two weeks before closing signing windows for its firmware, but has demonstrated a more aggressive approach to this behavior more recently.
Apple officially stopped signing iOS and iPadOS 13.3.1 Tuesday evening, just one week after releasing iOS and iPadOS 13.4 to the general public as an over-the-air software update.
The closing of the signing window means those who’ve upgraded to the newer 13.4 firmware will be unable to downgrade to 13.3.1. This isn’t a big deal for most iPhone or iPad users, but it’s something that can be particularly unsettling for the jailbreak community as software updates frequently patch jailbreak-centric software exploits.
