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

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.
Well-known iOS hacker and jailbreak developer iH8sn0w was the first to spot the reopening of the signing window, and we have since had multiple users confirm to us that they have successfully downgraded and re-jailbroken their devices. More after the fold… Read More

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

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 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

We’ve made a step-by-step tutorial that shows you how to use this new restore feature, along with getting by those pesky Mismatched APTicket errors. Check inside for the full tutorial. Read More

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
