When Apple closes the firmware signing window for iOS 8.3, users wishing to downgrade (or upgrade) to iOS 8.3 won’t be allowed to do so. Instead, you’ll have to settle for whatever firmware Apple is signing, which is usually the latest and greatest out there.
When that happens, it’s quite probable that it could spell the end of jailbreaking for a while—remember we just got out of a significant lull.
With this in mind, the ability to downgrade back to iOS 8.3 is very desirous for would-be jailbreakers. While there is no confirmed downgrade ability just yet, there are some things that you can do to ensure that you have the best chance to downgrade should that ability arrive.
This is accomplished by saving your iOS 8.3 SHSH blobs.
To save your SHSH blobs and prepare for a possible iOS 8.3 downgrade, you’ll need to use TinyUmbrella to do so. I’ll show you how in this post and video. Read More

Every time a beta is released, we always provide tutorials for those of you who may be developers, but to be honest, we know that even some of you non-developers with paid access to developer accounts will upgrade to the betas as well. Of course, that’s your own decision.
But with watchOS, things are different. You really shouldn’t upgrade to watchOS 2 unless you truly are a developer, or at the very least, you should thoroughly understand what you’re getting in to. Why is this? We explain in this post. Read More

Semaphore has been on a roll lately, as shown by the release of yet another TinyUmbrella beta build, and this version contains a significant new feature. You now have the ability to save SHSH blobs directly from a local device. This means that if you’re on a jailbreakable firmware like iOS 8.1.2, you can save the 8.1.2 blobs even though Apple is no longer signing that firmware version. Read More

TinyUmbrella, the tool that allows users to save SHSH blobs to be used for potential downgrades, has received another update. As we reported a few weeks ago, TinyUmbrella has made a significant comeback, and its developer, semaphore, is hopeful that downgrades to iOS firmware will be a real thing in the not so distant future.
With this in mind, semaphore is continuing to improve TinyUmbrella, and this latest beta version contains numerous fixes and iterative enhancements. If you still haven’t saved your SHSH blobs, I advise you to stop what you’re doing, download TinyUmbrella, and do so today. Read More

In case you missed our post over the weekend, TinyUmbrella, the popular tool associated with downgrading iOS firmware, is back with a brand new beta version. This is a significant new revelation for the jailbreak community that could have some far-reaching consequences when it comes to establishing potential downgrade options and protecting against Apple’s routine of closing firmware signing windows.
The new TinyUmbrella tool shares a lot in common with its predecessor, but it’s been a long time, and there’s enough differences to warrant a brand new walkthrough and discussion. In this video, I’ll show you how to save your iPhone, iPad, or iPod touch SHSH blobs, I’ll talk about what’s new with TinyUmbrella, and I’ll show you some of the things I’ve learned and encountered thus far.

As promised, Semaphore has released a rewrite of his popular TinyUmbrella tool for OS X and Windows. The tool, which has been completely rewritten from the ground up, is currently in beta and requires Java.
Semaphore has alluded to the fact that the new TinyUmbrella may have far-reaching consequences related to downgrading both 32-bit and 64-bit devices. Back in the original TinyUmbrella’s heyday, it was used as a tool to help downgrade to prior versions of iOS. Read More

I’m not sure why one would want to do that, but here is a friendly public service announcement to let you know that you can still downgrade to iOS 8.1.1 should you choose to. Following the release of iOS 8.1.2 yesterday, Apple still hasn’t closed the signing window of iOS 8.1.1, which means that if for some reason you have issues with iOS 8.1.2, you can still downgrade to iOS 8.1.1 and enjoy a stable jailbreak with TaiG.

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. Read More

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

Apple issued a support document Wednesday night detailing a “workaround” on how to revert back to iOS 8 for those users that were affected by the release of iOS 8.0.1 earlier in the day, an update which incapacitated iPhone 6 and iPhone 6 Plus devices.
Besides providing instructions on how to downgrade to iOS 8, the company noted that it is “preparing iOS 8.0.2 with a fix for the issue, and will release it as soon as it’s ready in the next few days.” Read More

So iOS 8.0.1 was filled with bugs that broke Touch ID and cellular data for many iOS users on the iPhone 6 and iPhone 6 Plus. But Don’t fret, if you’re in this precarious situation, we have an easy fix for you: Downgrade to iOS 8.0.
Well, actually, it’s sort of an upgrade in a weird and ironic way. Check inside for the full step-by-step tutorial. After you’re finished, your iPhone should work like normal. Read More

Those of you who are affected by the iOS 8.0.1 update from earlier today still have the opportunity to downgrade back to iOS 8. Unfortunately, downgrading requires your iPhone to be connected to a computer, which might be an issue for many people, but this is still an option. Read More

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

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
