Newly teased tfp0 bug supports iOS 13.3 and A12/A13 devices

Matrix code hacked iPhone.

It’s always exciting for the jailbreak community when someone comes forward with a brand-new bug that could potentially enable exploitation for jailbreaking newer devices and versions of iOS. After all, Apple tries very hard to keep iOS bug-free and quickly patches anything that even smells jailbreakable.

With that in mind, a newly-teased ‘tfp0’ bug shared first by @08Tc3wBB and later validated by security researcher @RazMashat would appear to be compatible with Apple’s latest and greatest iOS 13.3 firmware on handsets up to and including the A13 variety. Indeed; even the iPhone 11 Pro platform seems to be vulnerable:

Downgrades from iOS 13.3 no longer possible as Apple unsigns iOS 13.2.3

Apple stopped signing iOS 13.2.3 Thursday evening, barely over a week after releasing iOS 13.3 to the general public. It’s an expectable move on the company’s behalf that prevents iPhone and iPad users from restoring to that particular firmware version, or from downgrading from the newer iOS 13.3 release.

Apple’s official reasoning for doing this is to facilitate software upgrades to ensure that users take advantage of the latest features, bug fixes, and security patches. Behind that marketing façade, it’s also evident that Apple prevents software downgrades in an effort to keep the jailbreak community at bay, as most jailbreak tools only operate on older versions of iOS, and Apple quickly patches these jailbreaks in its software updates.
