A few days ago, well-known hacker and security expert Luca Todesco stated that he
Apple uses a two-pronged strategy toan endless game of cat and mouse to stay a little ahead of the jailbreakers. The company released a software update to fix security vulnerabilities that could be used to jailbreak it, as it did with iOS 10.2, and it also stopped signing the firmware files of older versions of iOS to ensure they can't downgrade back to the old one. version of iOS that can be jailbroken. Thus, for jailbreaking purposes, a tool for downgrading or upgrading the version of iOS that Apple has stopped signing would be very useful.

To be able to use the utilityPrometheus, the first step is to create a SHSH digital signature file. Hacker tihmstar has released a new tool called tsschecker that saves such a file in a new format called .shsh2. You can download this utilityvia this linkgithub, and usingthis is the guide, create a digital signature of your device in .shsh2 format. We will also try to publish a step-by-step guide very soon.

Tsschecher is currently only available for64-bit iOS devices. You will also need a jailbroken device to use the Prometheus utility to downgrade or upgrade the unsigned iOS firmware version. Jailbreak should also have “tfp0” functionality, although an alternative in the form of “host_get_special_port” is also suitable. Thus, a device hacked using Pangu 9.1 will be able to use the capabilities of the utility. Todesco's Pangu 9.3.3 web loader will also be able to work with this utility.
The hacker tihmstar also posted a video teaser, which shows the features of the utility in action:

Hacker tihmstar announced that he will release a utilityPrometheus on New Year's Eve. Therefore, if you have a hacked device, and are wondering: is it worth you to upgrade the firmware to 10.1.1 in order to be ready for the jailbreak 10.1.1 from Todesco. Utility from tihmstar gives you the opportunity to stay on the current version of the firmware, no matter how much that Apple closes the window for signing iOS 10.1.1. You can upgrade to firmware 10.1.1 only when a jailbreak is released for it. However, it is important that you save your digital signature in .shsh2 format as soon as possible, before Apple stops signing the iOS 10.1.1 firmware file.
