Prometheus Tool iOS Downgrade For iOS 10.2
If you’ve been following all the jailbreak news recently, you may be aware that iOS hacker tihmstar announced that he will be releasing the Prometheus downgrade tool soon. The good news is that he released the tool today and it is now available for download.
Prometheus is a tool that will allow jailbreakers to downgrade or upgrade to an iOS firmware version even when Apple stops signing it. The process of downgrading is not straightforward and requires saved .shsh2 blobs, otherwise you won’t be able to downgrade.
The hacker explains the entire process of downgrading in this video (or you can follow the step-by-step guide here):
Unfortunately, users on Reddit are reporting that Apple has already patched this hack. When using the Prometheus tool, an error will be displayed stating that Apple’s TSS server is down and that the firmware cannot be signed. Additionally, Apple’s TSS page is displaying a “Server not ready” message, which might be due to the fact that they are making changes to block any attempt to downgrade using Tihmstar’s tool.
Many non-jailbroken users are still able to update their devices, which is an indication that the TSS server is actually not down, but is blocking any downgrade attempts from the Prometheus tool.
It is no surprise that Apple has patched this hack so quickly, as any attempt to bypass their platform restrictions is frowned upon by the company. We’ve seen many times how responsive Apple has been in patching new jailbreak tools that get released to the public.
Tihmstar hasn’t responded to this news yet, so we’re yet to see an official statement from the hacker and if there’s any workaround to this patch. Stay tuned with us for further updates.
