Today hacker tihmstar released his tool Prometheus, which can be used (in some cases), to upgrade or downgrade iOS to currently unsigned firmwares. The tool is not foolproof however, so in this article I'll briefly explain what its limitations are and how to follow tihmstar's guidance on the tool.
Luca Todesco, better known by his handle qwertyoruiop, has just announced that the first betas of his iOS 10 jailbreak dubbed yalu are now out.
But before anyone begins prancing around and laughing out loud with sheer unadulterated joy, there are some caveats to take note of, as well as some risks to discuss.
TL;DR: do not use this tool unless you know exactly what you are doing.
Apple has stopped signing iOS 10.1 and 10.1.1 on Tuesday in a move that's sure to choke the jailbreak community a little bit further. It's typical of Apple to follow this kind of behavior after a new firmware release, so it's not surprising this would happen as iOS 10.2 was released just over a week ago.
With the firmware no longer being signed, downgrades to iOS 10.1.1 are currently no longer possible, so if you've upgraded to iOS 10.2 recently or need to do a fresh restore of iOS 10.1.1 in iTunes, then you're out of luck.
Update: This guide is now outdated, and simpler methods are available. We recommend that users use our simpler guide on saving blobs with TSS Saver instead. This guide will remain up for advanced users, who may still want the flexibility of this approach.
iOS hacker tihmstar has announced the upcoming release of his tool Prometheus. And no, it doesn't steal fire from the gods for you to foster the burgeoning potential of your race. Instead, he claims it will be the first tool capable of upgrading and downgrading 64-bit iOS devices to unsigned firmwares. If successful, this would be welcome news for the jailbreak community, allowing movement between firmwares for which you have saved your blobs, even after Apple's signing windows have closed.
With the news of a possible upcoming jailbreak for iOS 10.1.1, the race is on for those who have already upgraded past it to downgrade before Apple closes the signing window on them and leaves them high and dry. This guide will walk you through how to return to iOS 10.1.1 from iOS 10.2 (or any other version you may be on, like iOS 9.3.3 or iOS 10.1) so that you will be safe and sound when the window closes, and can wait and see if this jailbreak hype comes true.
Hot on the heels of this week's announcements about upcoming iOS 8.4.1 and iOS 9.3.x jailbreaks, there have been stirrings today which suggest we may also see our first iOS 10 jailbreak soon. It must be noted that these are at present just statements of intent rather than concrete, but that being said, they are more encouraging than most that we have seen lately, and in my tentative opinion will result in something being released sooner rather than later.
Back in November, India-based security researcher Hemanth Joseph discovered a bug in iOS 10.1 which permitted him to bypass Apple's anti-theft Activation Lock feature by entering an excessively long string of characters in the Wi-Fi setup text fields.
Apple has patched the flaw in iOS 10.1.1 but now, as noted by SecurityWeek, researchers at Vulnerability Lab have managed to find another method of bypassing Activation Lock protection on an iPhone, iPad or iPod touch with iOS 10.1.1 and they posted video evidence to prove it.
Many people are complaining about poor battery life after deploying the latest iOS 10.1.1 software update on their iPhone, which released for public consumption on October 31 and squashed bugs where Health data couldn't be viewed for some users.
Aside from this, it seems that iOS 10.1.1 is also causing some iPhones to shut down abruptly when the battery charge falls below a certain percentage, according to a thread on Apple’s support forums that at post time had thirteen pages.
A little more than a week following the public release of iOS 10.1.1 with bug fixes for Health data, Apple on Wednesday published a slightly revised build of the software update.
The Cupertino company admittedly has a good reason for replacing the existing iOS 10.1.1 installer on its servers with another one that shows a slightly bumped up build number.
We'll update the article when we learn more.
The new build of iOS 10.1.1 arrived two days after iOS 10.2 beta 2 was seeded to developers and less than 24 hours after its accompanying public beta launched.
There's really been a lack of news about an iOS 10 jailbreak recently, but despite any updates, we've been able to count on iOS hacker Luca Todesco to show off his personal jailbreaks running on iOS 10.
Now, another iOS hacker that goes by the handle @ijapija00 is demoing his jailbreak, only this time, the spotlight is on an iPhone 7 Plus running iOS 10.1. He claims it works on iOS 10.1.1 as well.
