The latest iTunes beta prevents iOS downgrades
We’ve ever been able to downgrade to a recent iOS version yesteryear installing an IPSW file on an iPhone or iPad through iTunes for Mac in addition to Windows, but that’s no longer possible inwards the latest iTunes 12.9 beta, distributed final calendar week equally role of the macOS Mojave 10.14.4 developer beta.
UPDATE: This is evidently the trial of a põrnikas rather than a modify of policy yesteryear Apple. Having reached out to Apple bespeak if the modify was deliberate or a bug, Cult of Mac was told that Apple hasn’t changed its policy on iOS downgrades.
As showtime noted on Reddit final night, in addition to confirmed yesteryear i of the commenters, Apple appears to convey disabled iOS downgrades via a locally saved IPSW firmware file inwards the latest iTunes 12.9.4.61 beta, fifty-fifty if the IPSW file is yet beingness signed yesteryear the company.
Here’s what the redditor wrote:
Discovered this equally I was trying to update my iPhone XS to iOS 12.1.1 (signed) using an IPSW file I downloaded from IPSW.me. The latest iTunes 12.9.4.61 beta in addition to Apple Configurator 2.8.2 convey seemingly disabled the Option+click update in addition to restore method, forcing you lot to utilisation the latest iOS version (currently 12.1.3).
I replicated this on around other motorcar in addition to spotted somoene bespeak virtually it on Twitter.
This was possible inwards the previous iTunes version. For example, the latest version of iOS is iOS 12.1.3 but you lot tin easily downgrade to the Apple-signed iOS 12.1.x firmware inwards iTunes 12.8.
This affects jailbreakers although at that topographic point are around border cases. For example, a critical flaw inwards the electrical flow iOS version may prompt the user to downgrade. In the past, people downgraded if an iOS software update slowed downwardly their device or introduced pregnant battery drain.
The poster advises using the stable iTunes 12.8 version or the iTunes 12.9.2.5 beta or older for restoring or downgrading to a signed iOS version that isn’t the latest.
iTunes 12.9.3.3 reportedly works, too.
Again, this modify (mostly) concerns jailbreakers who convey their ain reasons for downgrading because IPSW restoring volition hold out express to the latest available version of iOS on Apple’s servers.
I wonder if this is an intentional change. I mean, if the destination game hither is preventing people from downgrading, Apple could convey only stopped signing older iOS versions in addition to telephone telephone it a day.
So, what precisely is going on here, create you lot think?
