1. Compatibility
The ability to perform a modification of the operating system is fundamentally governed by device and software version compatibility. Not all devices running iOS 10 are equally amenable to such modifications. The existence of exploitable vulnerabilities within a specific build of iOS 10 for a given device model determines whether the operating system can be altered. If no exploit is available for a particular device and iOS 10 version, the process cannot proceed. This represents a binary condition: compatibility is either present or absent.
Failure to adhere to the specified device and software version compatibility will invariably result in failure and, potentially, rendering the device unusable. For example, an exploit developed for an iPhone 6s running iOS 10.2 will not function on an iPad Air 2 running iOS 10.3.1. The architecture differences and patched vulnerabilities in subsequent iOS versions render the existing exploit ineffective. Compatibility charts and community-maintained resources provide essential information regarding which devices and software versions are supported.
Therefore, verifying compatibility is the paramount first step. It dictates the subsequent actions and significantly reduces the risk of damaging the device. Ignoring this critical prerequisite guarantees a futile endeavor. Resources such as forums, dedicated websites, and reputable guides are essential for verifying device and software version support. A clear understanding of these limitations is crucial for making informed decisions.

This state is generally considered inconvenient due to its dependence on an external device.
-
Untethered State
An untethered state enables the device to boot fully and retain all modified functionalities independently, without requiring any external assistance. Upon each power cycle or reboot, the modifications are automatically loaded and applied by the operating system itself. This state provides a more seamless and user-friendly experience, mirroring the behavior of an unmodified device.
-
Semi-Tethered State
A semi-tethered state represents a middle ground between the two extremes. The device can boot on its own without computer assistance, but the modified features will not be active. The device functions as a standard, unmodified device until a software tool is used to re-enable the modifications. This provides a balance between functionality and convenience.
-
Impact on User Experience
The choice between tethered, untethered, and semi-tethered options significantly impacts the user experience. An untethered implementation offers the most seamless and convenient operation. A tethered solution, while less desirable, may be the only option available depending on the device, iOS version, and available exploits.
