In this article, I will guide you to install Fugu14, then jailbreak with unc0ver in an easy to understand way that anyone can do.
- Tethered Jailbreak mostly appear in recent jailbreak tools, implying that the jailbreak is only temporary. If you restart the device, the jailbreak will be lost. You must re-jailbreak the device.
- Untethered Jailbreak temporarily understood as “jailbreak forever” for easy understanding. That is, the jailbreak is only done once, your device will be jailbroken forever even after restarting the device. Of course, it does not take into account the case of upgrading to a new iOS version or restoring the device via iTunes.
