Apple Stops Signing iOS 18.4, Blocking Downgrades
Share
Apple has officially stopped signing iOS 18.4, meaning users can no longer downgrade or restore their devices to that version. This move comes shortly after the release of iOS 18.4.1, which is now the latest publicly available firmware.
If you’ve updated or restored your iPhone or iPad recently, you’ll now find yourself locked into iOS 18.4.1. For developers, Apple has already seeded iOS 18.5 beta 3, giving a glimpse of what’s ahead—but for users focused on jailbreaking, this development narrows your options.
As usual, the jailbreak community encourages users to remain on the lowest firmware possible to maximize their chances of jailbreaking. Currently, most public jailbreak tools support older firmware versions. Here's a quick look at the current jailbreak scene:
-
Unc0ver and Taurine support devices running iOS 14 through 14.8.1.
-
Unc0ver (with Fugu14 untether) supports iOS 14.3 through 14.5.1.
-
Fugu15 is available for developers on iOS 15.
-
Fugu15 Max is in beta for A12–A15 devices on iOS 15.0 through 15.4.1.
-
Dopamine 2.4.5 offers a semi-untethered jailbreak for M1 and A14 or earlier devices running iOS 16.5.1 or below.
-
Palera1n has been updated to support iPadOS 18 and iOS 17.3.1 for A11 and older devices.
For those looking to download the latest IPSW files manually, you can find them through resources like the iClarified IPSW Download Wizard. This remains one of the most reliable tools for retrieving firmware files directly:
As always, if you’re in the jailbreak community or simply want more control over your firmware version, it’s a good idea to keep a close watch on what Apple is signing. With iOS 18.5 on the horizon, we may see more updates coming soon.
