The Checkra1n utility that is in use to jailbreak certain iPhones can now be used from a rooted Android smartphone. A practice that could have interest in rare cases.
Only a few years ago, root and jailbreak were common. They allow respectively on Android and iOS to gain privileges at the system level in order to open new possibilities on our smartphones. But this manipulation is much less attractive now that most of these functionalities are now available natively.
Some nevertheless still like to engage in this practice and the Checkra1n tool precisely allows jailbreaking many iPhones under iOS 12.3 or higher (from 5 s to X). The big advantage of this tool is that it is based on a flaw in the Boot ROM and not on the OS itself, which prevents Apple from correcting the exploit with a simple update. It is nevertheless a semi-tethered jailbreak, which means that it is necessary to reconnect the iPhone to a computer to restart the jailbreak each time your restart your phone which is disturbing. In addition, the tool was available only on macOS 10.10 or higher.
