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

RedSn0w 0.9.15b1 was a gargantuan update. In fact, we’re still trudging through all of the new features. One new addition that has us really excited is the new direct restore option for pre-A5 devices.
This new restore option allows you to downgrade your device without having to fool with host files, stitching, Pwned DFU, iTunes, or anything else that made downgrading so incredibly cumbersome in the past.
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

Hot on the heels of the iOS 6 official release, the iPhone Dev Team, headline by its most prominent member, MuscleNerd, is making moves as well.
Today they introduce new RE-Restore functionality that will allow users on iOS 5.1.1 to restore their devices to a fresh install iOS 5.1.1. This can come in handy if you ever need a fresh install for whatever reason, i.e. a bad jailbreak install, etc.
For those eligible to use the RE-restore, this means that you never have to worry about losing your 5.1.1 jailbreak, as long as you don’t go near iOS 6. Check inside for the details… Read More

Last month, the Dev Team released a new version of RedSn0w that allowed iPhone 3G (and some 3GS) users to downgrade their basebands. This was a big deal for users who had been stuck on the problematic 06.15 bb.
Today, the Dev Team has pushed out an update to the jailbreak utility that greatly improves on this feature. The downgrading process has been made simpler, and now works on a much wider range of devices. Read More

So, you’d like to downgrade your iOS 6 beta install back to iOS 5.1.1? If you’ve ever dealt with downgrading firmware in the past, then you know how much of a pain it can potentially be. Fortunately when it comes to downgrading beta firmware back to public firmware, it’s extremely easy.
That’s because Apple is still actively signing iOS 5.1.1 due to the fact that it’s the latest public firmware available. Hence, you can easily downgrade without any tricks, host file changes, SHSH blobs, TinyUmbrella, etc. Literally, all you do is hook up your iPhone, go into DFU mode, open iTunes and downgrade. Watch our video inside to see how utterly simple the process is… Read More

Looking at the activity on that post we wrote, I’m sure many of you will be happy to learn that Musclenerd hinted earlier today at a release of the downgrade for this
When asked about an ETA of the project, Musclenerd replied: Read More

As most of you know, Apple released an update to iOS last week, bringing the firmware to 5.1.1. The new software doesn’t contain much more than bug fixes, but if you updated to it, you’ll want to save your SHSH blobs.
Luckily you can do that with the latest version of TinyUmbrella. NotCom has just released TU 5.11.00 with support for the latest version of iOS. And if you haven’t been saving your SHSH blobs, you might want to start… Read More

Yesterday, the Dev Team released one of the biggest updates to their RedSn0w utility in recent memory. The new version included a feature that allows A5 device owners to downgrade their firmware to one that is jailbreakable.
But those with an iPhone 4S who only had SHSH blobs saved from iOS 5.0.1 (build 9A406) haven’t been able to use the new feature to downgrade. Until now. RedSn0w 0.9.11b2 brings support for the forgotten firmware… Read More

We love our Windows readers and viewers, and to prove it we’ve created a video tutorial that shows you how to downgrade an iPhone 4S or iPad 2 using RedSn0w 0.9.11b1 on Windows.
The process is basically the same as what we showed you with the Mac version of RedSn0w, but this time around we downgraded an iPhone 4S instead of an iPad 2. The iPad 2, iPhone 4S and the New iPad — all being A5 devices — can be downgraded using this method…. Read More

It’s finally here folks, the official downgrade tool for A5 devices!
Indeed, you can now downgrade your iPhone 4S, iPad 2, or new iPad (iPad 3) with the latest version of RedSn0w 0.9.11b1. Downgrading will allow you to perform an untethered jailbreak on your iPhone 4S, or iPad 2 running iOS 5.0.1 firmware.

The Dev Team has just released a major update to its popular RedSn0w software, bringing the jailbreak utility to version 0.9.11b1. The update includes a new feature that will allow users to downgrade the firmware on their A5 devices.

Awesome news for those who accidentally updated the firmware for their A5 device (iPhone 4S, iPad 2, and the new iPad aka iPad 3), possibly resulting in the loss of the precious untethered jailbreak. MuscleNerd has announced that an upcoming update to RedSn0w will allow users to downgrade their firmware.
The only catch is that you have to have your SHSH blobs saved for the firmware that you wish to downgrade to. That means that if you purchased your iPhone 4S with iOS 5.1 pre-installed, there’s no way to downgrade to iOS 5.0.1 so that you can enjoy the benefits of pod2g’s untethered jailbreak… Read More
