iOS 8.2 beta 2 is no longer being signed

Jeff Benjamin ∙ February 27, 2015

Bad news for would-be jailbreakers of iOS 8.2 beta 1 or beta 2—both firmwares are no longer being signed. There seems to be conflicting reports going around about whether or not Apple has killed access to beta 1, beta 2, or both beta firmwares, but I can personally confirm that Apple has shut down access to both.

Why is this significant? It's significant because iOS 8.2 beta 1 and beta 2 were the only firmwares available that allowed users to jailbreak using PP Jailbreak on Mac or TaiG on Windows.

Jailbreakers beware: iOS 8.1.2 is no longer being signed

Jeff Benjamin ∙ February 10, 2015

iOS 8.1.2 met its end today, as Apple pulled the plug on its signing status. This means that iOS 8.1.2 can no longer be installed on a device, and as such, you can no longer jailbreak if you restore your device. Jailbreakers will need to stay where they are on iOS 8.1.2 if they want to keep their jailbreaks.

Apple brings the iOS 8.1.1 signing window to a close

Jeff Benjamin ∙ December 17, 2014

I've got good news and bad news. The bad news is Apple is no longer signing iOS 8.1.1. That means that anyone wishing to upgrade or downgrade to iOS 8.1.1 can no longer do so. Users will now be forced to upgrade to iOS 8.1.2.

Fortunately, there's good news. The good news is that Apple is of course signing iOS 8.1.2 being that it is the latest publicly available firmware. Since iOS 8.1.2 is jailbreakable with the latest version of the TaiG jailbreak, jailbreakers need not be overly concerned.

Apple stops signing iOS 8.1, downgrade now impossible

Jeff Benjamin ∙ December 1, 2014

iOS 8.1's day has come and gone. Today, in fact, just a few minutes ago, Apple stopped signing the firmware.

If you missed out on iOS 8.1, there is no way to either upgrade to it, or downgrade to it. Instead, you'll have to go directly to iOS 8.1.1.

Fortunately, like the firmware it replaces, iOS 8.1.1 is jailbreakable as well. Check inside to see what this means for the future of jailbreaking iOS.

How to reliably check Apple’s firmware signing window

Jeff Benjamin ∙ Updated April 18, 2018

If you accidentally upgrade to iOS 8.1.1 or any other non-jailbreakable firmware in the future, it's always a good idea to go out and check Apple's signing window to see if you can downgrade your device to a previous firmware. For example, if I upgrade my device to iOS 8.1.1 today, or if I want to check out Apple's iOS 8.2 beta, I know that I can do so and downgrade back to iOS 8.1 with no issue.

But remember, Apple's signing windows are subject to relatively quick closure. It's been four days since Apple released iOS 8.1.1, but the signing window for iOS 8.1 is still open, making it possible to downgrade now. That can, of course, change at any time. In fact, Apple could decide to close the signing window as you're reading this post.

For that reason, its a good idea to downgrade now if you ever want to jailbreak iOS 8. But it's also good to get familiar with how to check the signing window, and this handy website allows you to do just that.

How to downgrade to iOS 8.1

Jeff Benjamin ∙ Updated April 18, 2018

If you want to jailbreak iOS 8.1, but you're running iOS 8.1.1 or the new iOS 8.2 beta, you can downgrade your firmware to iOS 8.1 and jailbreak as long as Apple is still signing the iOS 8.1 firmware. As of this post, 8.1 is still being signed, but that will change in the future, so use this post to determine whether or not this tutorial is still valid.

If Apple is signing iOS 8.1, it's extremely easy to downgrade your device, even if you're running the iOS 8.2 beta or iOS 8.1.1. Neither of those firmwares are jailbreakable at the moment, but iOS 8.1 is jailbreakable, hence the need to downgrade. Follow our simple tutorial after the break to downgrade your device back to iOS 8.1.

Apple is still signing iOS 8.1, if you’re interested in jailbreaking, you better restore now

Jeff Benjamin ∙ Updated April 18, 2018

Apple just released iOS 8.1.1, which kills the Pangu jailbreak. The good news is that it is (as of the writing of this post) still signing iOS 8.1. This means that you can still install iOS 8.1 and jailbreak for the time being.

But you better act fast. Apple has been very unpredictable when it comes to closing its signing windows. Once the window for iOS 8.1 is closed, you will not be able to upgrade or downgrade to iOS 8.1. You'll have to go directly to iOS 8.1.1, which renders your device unjailbreakable.

Apple releases iOS 6.1 beta 5 to developers

Jeff Benjamin ∙ Updated April 11, 2018

Well, that was a bit unexpected. Apple just released iOS 6.1 beta 5 to developers. The release comes just hours before the previous beta, beta 4, was scheduled to expire.

As we noted in a previous post, this is only the second time that Apple has released a fifth build for a non-major iOS update. Developers can head over to the development portal now to download the latest beta release.

How to downgrade iOS 6 to iOS 5.1.1 on A4 devices

Jeff Benjamin ∙ Updated April 10, 2018

Have an iPhone 4, iPod touch, or below running iOS 6, and would like to downgrade back to iOS 5.1.1? Doing so is easy is you have your SHSH blobs saved for iOS 5.1.1 and can follow the steps inside. Unlike the beta period of iOS 6, you must have your SHSH blobs for iOS 5.1.1 save for you device now, because Apple has stopped signing iOS 5.1.1.

To downgrade, you will need the latest public version of RedSn0w. We will use the SHSH Stitching feature to combine the appropriate IPSW file for 5.1.1 and your corresponding SHSH blob for the device you wish to downgrade. It may sound a bit confusing, but it's extremely easy if you follow along carefully.

Take a look inside for the full walkthrough and video how-to.

Apple releases an updated version of iOS 5.1.1 for the iPhone 4 GSM

Jeff Benjamin ∙ May 25, 2012

As 9to5 Mac first reported, Apple has released an updated version of iOS 5.1.1 for the iPhone 4 GSM. The build for this latest version is 9B208, while the previous version was 9B206. Interestingly enough, the release is only for the iPhone 4 GSM, and it's likely a small bug fix given its slight build number difference.

Either way, we recommend that you hold off on updating until given the all clear is sounded with regard to jailbreak compatibility. Make sure your save your iOS 5.1.1 SHSH blobs so that you can take advantage of a future downgrade if need be.

How to Permanently Preserve Your iOS 5.0.1 Untethered Jailbreak

Jeff Benjamin ∙ January 6, 2012

If you've been paying attention to the jailbreak scene lately, then you've heard the warnings about preparing for Apple's next counter move against jailbreakers. The question is this: have you heeded it?

It's imperative that you update to iOS 5.0.1 now and save your SHSH blobs across all devices, including the iPhone 4S and iPad 2. That way, you can always downgrade to iOS 5.0.1 later, which means you will always have access to an untethered jailbreak.

We'll show you how to create a firmware file for your A4 devices that can always be jailbroken. We'll also tell you what to do to preserve the jailbreakability of your A5 devices as well. If you haven't done this yet, now is the time to act...

New iOS 5.0.1 Release Makes iPhone 4 Siri Port Legally Feasible

Jeff Benjamin ∙ December 16, 2011

You may have noticed that Apple released an updated version of iOS 5.0.1 not too long ago, and with it comes some interesting news regarding security.

It appears that the new iOS 5.0.1r2 features decrypted ramdisks, which means that it now possible to write a script to download the 5.0.1 and extract the necessary files needed for a Siri port.

Since the download is publicly available from Apple's server, the idea of a Siri port just got a lot more legal...
