How to verify your .shsh2 blobs with img4tool

Joaquim Barbosa ∙ Updated February 23, 2021

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.

The Binding of Isaac: Rebirth arrives after being yanked from App Store almost a year ago

Christian Zibreg ∙ January 11, 2017

The Binding of Isaac: Rebirth, an iOS version of the dungeon crawler game originally released back in 2014 by independent game studio Nicalis, is now available on iOS as a premium $14.99 download from App Store.

Nicalis originally submitted its dungeon crawler for iPhone and iPad a year ago, but the game got rejected for depicting violence against children. The iOS port has a 17+ rating.

CoolBooter demo: the dual-boot tool for iOS

Joaquim Barbosa ∙ Updated April 20, 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.

Senior Director of Design for Mac lineup leaves Apple for engineering role at Tesla

Christian Zibreg ∙ January 11, 2017

Apple was trying “very hard” (in Elon Musk's own words) to recruit top talent from Tesla.

Now that its Project Titan has shifted gear from building an electric vehicle to developing an autonomous driving software, some of the engineers associated with the initiative have departed for Tesla.

Just as we've discovered that Swift creator Chris Lattner was leaving the iPhone maker to take a position as Vice President of Autopilot Software at Tesla, Electrek.co is reporting that the guy who designed many of Apple’s iconic Macs will now be building Tesla vehicles.

Christian Zibreg ∙ January 11, 2017

After sharing images and a video of an early-stage prototype iPhone software based on iPod's click wheel interface, leakster Sonny Dickson is back at it with another wonderful piece of Apple history.

A new video posted on Dickson's website pits a pair of early iPhone prototypes against each other: Tony Fadell’s “P1” device based on the click wheel UI and ex-iOS chief Scott Forstall's “P2” project.

Why you should wait until Luca Todesco’s iOS 10 jailbreak is out of beta before using it

Anthony Bouchard ∙ January 11, 2017

I get asked every day whether or not someone should jailbreak their iOS 10 device right now with Luca Todesco’s beta tool or continue to wait a little longer for a more stable jailbreak release.

In this post, I hope to tackle some of the confusion regarding the tool and help to answer some ongoing questions of whether or not you should jailbreak just yet. Of course, if you don’t have the time to read, the short answer is: no.

Apple’s failed sapphire plant will now build server cabinets for its global data centers

Christian Zibreg ∙ January 10, 2017

Apple's failed sapphire crystal manufacturing facility in Mesa, Arizona will be repurposed to produce server assembly cabinets for the Cupertino firm's global data centers, according to a notification published by the Federal Register and cited yesterday by Business Insider.

Apple already has authority to produce certain components for consumer electronics in a special zone that exempts it from customs duty payments, but now it's looking for approval from the Foreign-Trade Zones Board to produce “finished products and foreign status materials and components” in the Mesa factory.

Foxconn reports first ever annual sales decline since going public 25 years ago

Christian Zibreg ∙ January 10, 2017

iPhone manufacturer Foxconn Technology Group posted its first ever sales decline since it went public back in 1991, Japanese outlet Nikkei reported Tuesday. The outlet expectedly blames “lukewarm demand” from Foxconn's biggest client Apple and the “saturated smartphone market” for the 2.81 percent drop in annual sales.

For context, Foxconn earns more than half of its revenue from doing business with Apple. The Taiwanese company is also known as Hon Hai Precision Industry and assembles iPhones and other gadgets like PlayStation consoles, notebooks, wearable devices and so forth on a mass scale.

Cody Lee ∙ January 10, 2017

Apple has come to the conclusion that a hidden setting in Safari caused the odd battery results in Consumer Reports' MacBook Pro review that kept the publication from recommending the laptop. In a statement to AppleInsider, the company said it worked with CR's team over the holidays and determined that its testing methods were flawed.

Apple patents tiny thru-holes in OLED display, HUD windows & more slick tech for full-face iPhone

Christian Zibreg ∙ January 10, 2017

A new patent No. 9,543,364 for “Electronic devices having displays with openings” has been awarded to Apple this morning by the United States Patent and Trademark Office (USPTO). First filed for in February 2015, this newly granted patent reveals more ways iPhone 8 will outclass Android rivals.

The invention would basically put some common components typically found on the front face of the phone behind the display assembly.

What components are we talking about?

Well, stuff like the earpiece, forward-facing cameras, Touch ID and various sensors. Integrating such parts behind the display assembly would help design a truly edge-to-edge device. Apple is thought to be working on such designs for its upcoming OLED-based iPhone 8 refresh.
