In the last few minutes Apple closed the signing window for iOS 10.2. That means that you can no longer upgrade, downgrade, or restore to that firmware, either over-the-air or through iTunes. You also can no longer save blobs for iOS 10.2 through any tool.
This guide will walk you through how to restore a second, third, or fourth generation Apple TV. The now obsolete first generation Apple TV and the Apple TV 4K cannot be restored using this method.
The process comes in handy for upgrading and downgrading to signed firmwares, but also for restoring the device if it has problems or needs a fresh start.
We recently covered the release of Luca Todesco's first build of yalu102. This tool will eventually allow all 64-bit devices to jailbreak iOS 10. iPhone 7 and iPhone 7 Plus will be able to use it on iOS 10.0-10.1.1, all other 64-bit devices will be able to use it on iOS 10.0-10.2.
As the signing window for iOS 10.2 could close at any time, the pressure is on to downgrade to iOS 10.2 if you are currently on a higher firmware. Some people on a lower firmware should also upgrade to iOS 10.2, but not everyone. In this guide, we'll talk you through how to upgrade/downgrade to iOS 10.2 from a lower/higher firmware, if you are one of the people who should be there.
What with the release of iOS 10.2.1 and the soon-to-be-closed signing window for iOS 10.2, many people are wondering what the best strategy is for their device. Should they stick with a jailbroken firmware or jump to iOS 10? If they're already without a jailbreak, which iOS version do they need to be on to make sure they get one? What do they need to do to be able to upgrade to iOS 10.2 later, and keep their jailbreak for now?
In this article, we'll quickly go through what we consider the smartest options for each device and iOS version, so that you can (hopefully) make an informed decision.
Extensively updated to reflect beta release of Yalu for 10.2.
We recently reported how some of the .shsh2 blobs saved with previous versions of tihmstar’s TSSChecker were faulty. One problem affected all iPhone 7 and iPhone 7 Plus blobs, rendering them useless. This issue has now been fixed going forward, though past blobs are invalid.
The other problem was more complex and affected only certain models of certain devices. It is also fixed for blobs saved from now on, but given these occurrences, it is important to be able to check whether the blobs you saved in the past are in fact valid and fit for use with Prometheus.
In this article, we’ll go through how to use another tool from tihmstar’s Prometheus suite, img4tool, to verify that your .shsh2 files are good. This method will clarify whether you are affected by the second problem mentioned above, but will also work in general, when checking the validity of your blobs in future.
It seems tihmstar has been busy putting right the flaws in his suite of tools; just one week after he revealed that a bug in his .shsh2 saving tool TSSChecker had led to all iPhone 7(+) blobs saved with it being invalid, a new update restores the ability to correctly save blobs on Apple's most recent flagship device.
It's been a busy period for tihmstar's suite of tools since the release of Prometheus during the 33c3 convention. Both TSSChecker and Prometheus have seen some problems, as well as updates in the intervening period, and this article will bring you up to date with their current statuses.
Update: tihmstar has stated that the tool is working perfectly, and that he has used it successfully multiple times today. However, some users have been encountering a TSS server error when using the tool nonetheless.
Hot on the heels of Prometheus' release at the 33c3 convention two days ago, tihmstar's tool for upgrading and downgrading to unsigned iOS firmwares seems already to have hit a snag. Following some changes to Apple's TSS servers today, the nature of which are yet to be investigated, the tool has been rendered non-functional at the present time.
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.
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.
After seeing in iFixit's teardown that the base model of the new 2016 MacBook Pro without the Touch Bar had a removable PCIe SSD storage unit, many were excited at the possibility of aftermarket upgrade parts across the new MacBook Pro lineup.
But new images surfacing on the web this week after the first MacBook Pro with Touch Bar units began reaching the hands of buyers are showing that the Touch Bar models don't follow suit and have SSD storage chips soldered into their logic boards instead.
