Apple no longer signing iOS 7.1.2, closing the downgrade window

By Cody Lee on Sep 26, 2014

Apple has finally ceased signing iOS 7.1.2 today, notes hacker iH8sn0w, more than a week after releasing iOS 8 . This means that you can no longer downgrade to the older firmware from iOS 8.x, or upgrade to it from older versions.

This is a big deal for jailbreakers, as 7.1.2 is the latest firmware that can be jailbroken, and there won’t be one on iOS 8 for the foreseeable future. But it also affects average users too, as those not happy with iOS 8 can no longer revert. Read More

How to downgrade iOS 8 to iOS 7.1.2

By Jeff Benjamin on Sep 20, 2014

If you’re interested in downgrading your iOS device from iOS 8 back to iOS 7.1.2, you can still do so for a limited time. Obviously, your device must be capable of running iOS 7.1.2 in the first place, so devices like the newly released iPhone 6 and its larger brethren, the 6 Plus, do not qualify.

Downgrades are only possible when Apple is signing the firmware that you wish to downgrade to. Traditionally, Apple is fairly fast with its cutoff point, as it usually stops signing firmware that’s not the current release, in short order.

As of this post, Apple is still signing iOS 7.1.2, so if you wish to downgrade, you better act fast. Inside, we’ll walk you through downgrading to iOS 7.1.2 on an iPhone 5s, but the same rules apply to any device that is currently running iOS 8, but is capable of running iOS 7.1.2. Read More

 

How to downgrade from iOS 8 beta to iOS 7.1.1

By Joe Rossignol on Jun 8, 2014

Apple releases a new iOS version every year for iPhone, iPad and iPod touch. The public release is usually preceded by about three months of beta testing among developers, but shady UDID registration websites and other loopholes allow for regular users to install the pre-release software too. Then, like clockwork, a portion of those users encounters bugs, end up with a device stuck in recovery mode or simply want to downgrade to the previous iOS version.

First and foremost, we recommend staying away from pre-release software. I can certainly understand the excitement that surrounds updating to the latest iOS version, but betas are designed solely for developers to report bugs and test compatibility with their apps. But regardless of whether you’re an end user, or a registered developer, we’re here to help. Read ahead for step-by-step instructions on how to downgrade from iOS 8 beta to iOS 7.1.1…  Read More

 

Apple randomly signing iOS 6.0.x firmware [update: signing is over]

By Cody Lee on Jul 25, 2013

Good news for folks who lost their jailbreak updating their iOS device to try out iOS 7, it appears that Apple is currently signing 6.0.x versions of iOS firmware. This means that you should be able to downgrade your iPhone or iPad to iOS 6 and re-jailbreak.

How to downgrade iOS 7 to iOS 6.1.3

By Jeff Benjamin on Jun 11, 2013

Apple makes it sound like a life or death scenario when developers decide to install iOS 7 beta on a test device. In fact, it’s always done so with its beta releases. In the notes for iOS 7, Apple states that “Devices updated to iOS beta can not be restored to earlier versions of iOS.”

The thing is, that simply isn’t true. I’ve always been able to successfully downgrade my firmware in the past for a beta test device, and I’ve confirmed that the process still works perfectly fine on iOS 7. In fact, it’s extremely easy to downgrade your firmware from iOS 7 to iOS 6.1.3; it doesn’t even require any special tricks or techniques like some downgrades do. Check inside as I walk you through the extremely simple step-by-step process for downgrading iOS 7 back to iOS 6.1.3. Read More

 

Cydia introduces new TSS Center, Saurik explains what happened to iOS 6 TSS data

By Jeff Benjamin on Apr 10, 2013

Recently, Saurik, the creator of Cydia, posted a new blog entry explaining the history of Cydia’s TSS caching capabilities. As you know, Cydia has been able to automatically save off SHSH blobs for potential downgrade ability with jailbroken devices.

Things have changed rapidly over the years as iOS’ security evolved. The earlier versions of iOS included absolutely no downgrade protection. Eventually, with the adaption of TSS, basic verification to make sure that you were installing newer firmware, instead of older firmware arrived. This security was enhanced further with the adoption of a new verification scheme — APTicket — which has proved to be a pain in the rear for would be downgraders. Yes, there have been, and will always be a few exceptions to that rule, but for the most part, Apple has done a good job of cutting off the ability to downgrade firmware.

What does all of this have to do with Cydia’s new TSS Center? Well as it turns out, the APTickets saved for iOS 6.0-6.1.2 are all “useless”, as they’re incomplete tickets unsuitable for booting a device.

In a post on his blog named Where did my iOS 6 TSS data go? Saurik explains in verbose detail the issue at hand… Read More

 

Winocm developing iOS 6.X to iOS 5.1.1 downgrade, includes A5+ devices

By Mike Schnier on Jan 31, 2013

Winocm tweeted today that he was working on a method for downgrading from iOS 6 to 5.1.1 that will work on all devices. This is noteworthy as downgrades on most A5+ devices were either difficult, in the case of the iPad 2, or not possible in Redsn0w once Apple stopped signing the iOS 5 firmware.

Winocm is known for his work in PS3 firmware hacking and contributes tweaks such as CameraConnector to Cydia under the name ‘rms’. Winocm seems to be working on a lot of projects: A day before the downgrade tweet, Winocm posted a video of linux booting up on an iPhone 4 to YouTube (pictured above)… Read More

How to downgrade iOS 6 to iOS 5.1.1 on A4 devices

By Jeff Benjamin on Sep 28, 2012

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. Read More
