That’s it, folks. If you haven’t upgraded to iOS 8.4, it’s now too late. Apple has closed the iOS 8.4 signing window according to IPSW.me. It’s now impossible to upgrade or downgrade to iOS 8.4. All users are now forced to iOS 8.4.1 or higher upon restore.
Apple released iOS 8.4.1 last week which not only patched exploits used by TaiG iOS 8.4-8.1.3 jailbreak tool, but 40 other security bugs as well that could have been used in a future jailbreak tool for iOS.
Fortunately, it seems as if most people heeded our warnings when it came to getting back on iOS 8.4 before the signing window closed. If you didn’t, and you’re not already on iOS 8.4 or other jailbreakable firmware, you’ll need to wait until an iOS 8.4.1 jailbreak is released or an iOS 9 jailbreak is released.
As for any future jailbreak for iOS 8.4.1, while Pangu has demonstrated that they possess new jailbreak exploits which are capable of jailbreaking iOS 8.4.1, they will likely not make them public now for a minor update like iOS 8.4.1, especially with iOS 9 just around the corner. We’ll obviously keep you updated with any further progress on this, so stay tuned to us for more development on this.
Apple is expected to release iOS 9 alongside iPhone 6s and iPhone 6s Plus next month in September, followed by new iPads with iOS 9.1 in October. If there’s ever going to be another public jailbreak for iOS, it won’t be released before iOS 9 is made public.
If you’re currently on iOS 8.4, be sure to stay there and don’t upgrade to iOS 8.4.1 or later. If you want to restore your device, you can always use Cydia Impactor, a tool that lets you restore iOS and remain on the same firmware.
Just stay away from iOS 8.4.1 as far as possible. You’ve been warned.
