Apple has been the use of a two-pronged technique to keep forward of the cat and mouse recreation with jailbreakers. It's been freeing device updates to patch safety vulnerabilities that may be used for a jailbreak like they did in iOS 10.2, they usually additionally prevent signing the firmware information of older iOS variations, to make certain that jailbreakers can not downgrade again to an iOS model that may be jailbroken. So a device to downgrade or improve to an iOS model that Apple has stopped signing can be somewhat groundbreaking.
To make use of the Prometheus device, you first want to save the SHSH blobs. tihmstar has launched a brand new software referred to as tsschecker, which saves them in a brand new layout referred to as .shsh2. You'll be able to obtain it from this github link, and use this guide to save the .shsh2 blobs. We will be able to additionally submit a step by step information in a while.
The tsschecher is lately to be had just for 64-bit iOS units. You may even want a jailbroken tool to use Prometheus to downgrade or improve to an unsigned iOS firmware. The jailbreak additionally will have to have “tfp0” capability, despite the fact that “host_get_special_port” workaround can be wonderful. So a tool jailbroken the use of Pangu 9.1 can be eligible. Tudesco’s web-based Pangu 9.3.3 jailbreak loader additionally allows it.
Tihmstar has elaborated further on the workings of the tool, and in addition posted a teaser/rationalization video which presentations the primary steps of the use of it, which you'll be able to watch beneath.
For some, the method of saving the .shsh2 blobs could also be an excessive amount of trouble or they would possibly not get spherical to it in time, however although now not, the free up of this software indicates one thing thrilling for the group. After years of devs and bloggers like me telling folks to save their blobs simply in case, it's been confirmed once more that given sufficient time, a means may also be discovered to leverage them in an unsigned downgrade/improve. Even if the present usages could also be restricted (as other folks would possibly not have the right kind .shsh2 stored in time, or would possibly not have a jailbreak to transfer from), the truth that 64-bit units can also be manipulated on this method is information in and of itself. Who is aware of what different enhancements may also be made to the procedure in long run?
