iOS 10.3.1 signing is closing fast. With weak rumours of a possible iOS 10.3.1 jailbreak at some point in the future, we go through whether you should upgrade, downgrade, or save blobs before time runs out.
With Apple’s ever-turning iOS signing machine, many jailbreakers are forever wondering what the best strategy is for their device. In this article, we’ll quickly go through what we consider the smartest options for each device and iOS version so that you can make an informed decision.
I reported a few weeks back on an interesting new bug for 32-bit devices, which allowed you to restore them to any unsigned iOS 9.x firmware, provided you had blobs for the destination firmware.
At the time, it was thought that the bug would mainly be of use for people downgrading from iOS 9.3.5 to a lower firmware, to jailbreak with Home Depot or Pangu9. However, it turns out the bug is in fact more powerful and wide-ranging than previously thought, and may have much wider utility.
As you may recall, software internals consultant Jonathan Levin recently released LiberTV, a jailbreak tool for tvOS 9.1-10.1.
Based on Luca Todesco and Marco Grassi’s work which brought us the Yalu jailbreaks for iOS 10.0-10.2, Levin’s original work covered the equivalent tvOS firmwares, up to a maximum of tvOS 10.1. However, Levin may be able to go one better, based on a tweet posted today.
The signing window for iOS 10.2.1 could close any moment now, what with the upcoming release of iOS 10.3, so this is your last chance to save your blobs for iOS 10.2.1, or to downgrade to it from the iOS 10.3 betas.
iOS 10.2.1 is not currently jailbroken, so at the moment its blobs are not of use, nor is being on that firmware a guarantee of a jailbreak. However, you never know what’ll happen, so act now! Don’t be left out in the cold when signing ends.
As some of you may have seen from my tweet yesterday, there is some exciting news afoot for owners of 32-bit devices on iOS 9.
A group of developers including alitek12, ee_csw and Trevor Schmitt have stated that they are working on a downgrade solution which will allow users of legacy devices to escape from iOS 9.3.5 and return to a jailbreakable iOS 9 firmware.
This is an introductory article which explains how to follow our two-part guide on using the Prometheus downgrade tool.
Before attempting either Part 1 or Part 2 of the guide, everyone should read this article. It explains whether the guides apply to you, and if they do, which ones you should follow, as well as making sure that you fulfil the requirements for them to work.
This is Part 1 of a two-part guide on how to use Prometheus.
Before attempting this guide, everyone should read the introductory article, Prometheus Guide: Introduction. This will explain whether the guides apply to you, and if they do, which ones you should follow, as well as making sure that you fulfil the requirements for it to work.
If you currently have a jailbreak and you want to move to a different firmware with Prometheus’ nonceEnabler method, you must follow Parts 1 & 2 of the guide.
If you currently have no jailbreak, and you want to move to a different firmware with Prometheus’ nonce collision method, skip Part 1 and do only Part 2 of the guide.
