Delta emulator for iOS beta 2 released

by Joaquim Barbosa on Jan 18, 2017

Riley Testut’s new project Delta, the retro game console emulator, continued its early phase testing yesterday, with the release of a second build for those on its closed beta testing program. According to Testut, healthy feedback from the testers resulted in a slew of bugs and improvement suggestions reported from the first beta, and this second iteration consequently comes with a handy list of fixes and additions.

How to save jailbreak tweaks on your device with redeb

by Joaquim Barbosa on Jan 16, 2017

Sometimes a developer’s repo goes down, they withdraw a tweak, or they update the tweak on their repo and don’t leave your favoured previous version up. In these cases, you may want to save the tweak to your device so as to have it for later use.

The trouble is that Cydia removes the install files, saved in .deb format, after it has finished installing the tweak to your device. So unless you save the .deb file after you download it from Cydia, but before it installs (which is unlikely as it’s cumbersome and easy to forget to do), you would seem to be out of luck. But are you? In this guide, we’ll show you how to repackage already installed tweaks into .deb files for safekeeping, using redeb. Read More

 

How to customize the “About This Mac” section of a Mac

by Joaquim Barbosa on Jan 13, 2017

The “About This Mac” window contains information relating to your computer specifications and OS version, and is useful for quickly checking any of those details. However, it’s a little impersonal, and often (on a Hackintosh), incorrect. If, like me, you enjoy customising your machine to your own personal taste then this guide should help somewhat, by jazzing up the “About This Mac” section. Read More

 

How to verify your .shsh2 blobs with img4tool

by Joaquim Barbosa on Jan 11, 2017

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.

CoolBooter demo: the dual-boot tool for iOS

by Joaquim Barbosa on Jan 11, 2017

Developer Jonathan Seals recently released a new piece of work called CoolBooter, an interesting tool which allows some 32-bit devices to dual-boot different iOS firmwares. With a simple reboot it can allow, for example, switching between iOS 6 and iOS 9. Whilst this functionality is commonplace in the desktop computing world, booting multiple operating systems on iOS devices is much rarer.

Sebastien and I talked briefly about the tool on Let’s Talk Jailbreak 157, and in this article I’ll give some more info, as well as a video demonstration of it in action. Read More

 

iOS 10.2 jailbreak could come via YaluX update

by Joaquim Barbosa on Jan 9, 2017

The creator of the iOS 10.1.x jailbreak YaluX has announced that he intends to update the tool, currently in beta, to add support for iOS 10.2. Luca Todesco tweeted that his solution for the instability of the early builds of his tool has tangentially allowed for compatibility with the most recent firmware, news which will no doubt delight many in the jailbreak community who are trapped on iOS 10.2, and who have been lamenting the death of the jailbreak on currently signed firmwares.

TSSChecker now correctly supports iPhone 7 and iPhone 7 Plus

by Joaquim Barbosa on Jan 6, 2017

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.

Yalu + mach_portal now supports TSMC models: still unstable

by Joaquim Barbosa on Jan 6, 2017

Luca Todesco’s beta jailbreak for iOS 10.1.x, dubbed YaluX or Yalu + mach_portal, slightly broadened its device support list recently by adding the iPhone SE (TSMC chip version) and iPhone 6s(+) (TSMC chip version) to the club. Bear in mind, we do not yet recommend the tool to the average user, and Todesco himself has spoken of the possible difficulties brought about by too many people making use of the tool in its unfinished state.

Prometheus and TSSChecker: recent developments you should be aware of

by Joaquim Barbosa on Jan 3, 2017

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. Read More

 

Changes to Apple’s TSS servers currently render Prometheus non functional

by Joaquim Barbosa on Dec 30, 2016

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. Read More

 

Cydia beta for iOS 10.1.x jailbreak released

by Joaquim Barbosa on Dec 30, 2016

Thursday saw the release of a new build of Cydia from its creator Jay Freeman (Saurik). Coming in at version 1.1.28, the build is marked as a beta, designed for use with the fledgling iOS 10.1.x jailbreak from Luca Todesco.

Although I still do not recommend the average user to jailbreak with Yalu for 10.1.x, those who are confident doing so and have already taken the plunge may find this Cydia release improves their experience running the jailbreak slightly. Read More

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.

iOS 10 jailbreak beta released (but stay away for now)

by Joaquim Barbosa on Dec 21, 2016

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. Read More

How to save your .shsh2 blobs automatically online with TSSSaver

by Joaquim Barbosa on Dec 20, 2016

A couple of days ago, we covered how to save your .shsh2 blobs manually with tsschecker, and many of you have reported back saying you managed to successfully grab them. However, if you haven’t got them yet and don’t feel tech-savvy enough to mess around with the Terminal commands required, you can try this online tool instead which should save them for you.

How to save .shsh2 blobs for Prometheus with tsschecker

by Joaquim Barbosa on Dec 18, 2016

As reported on iDB earlier, iOS hacker tihmstar has announced a New Year’s Eve release of his new tool Prometheus, which can downgrade/upgrade devices to unsigned firmwares, subject to certain requirements.
The main prerequisite for using the tool is having the APTicket/.shsh for the firmware you want to go to, but the process for saving these has changed. You must now use his tool tsschecker to correctly save the files, dubbed .shsh2. This guide will walk you through how to do it. Read More

 

Prometheus: upcoming tool may allow unsigned iOS upgrades and downgrades

by Joaquim Barbosa on Dec 18, 2016

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. Read More

 

How to downgrade from iOS 10.2 to iOS 10.1.1 to prepare for a possible jailbreak

by Joaquim Barbosa on Dec 16, 2016

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.

iOS 10.1.1 jailbreak could be released in the near future

by Joaquim Barbosa on Dec 15, 2016

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.

by Joaquim Barbosa on Dec 15, 2016

Whilst most are no doubt still eagerly awaiting a jailbreak for the just-released iOS 10.2, there are those who still have devices on various flavours of iOS 9 and older, who have fallen through the cracks of the most recent Pangu releases. For them, this week brought some hope, with two separate announcements of upcoming jailbreaking tools, in addition to the release of a browser-based tool from Luca Todesco. This round-up will cover the various pieces of jailbreak release news that came to light over the past few days.
