iOS Jailbreaking: Patching Kernel on Boot
Which IOS jailbreaking technique patches the kernel during the device boot so that it becomes jailbroken after each successive reboot?

Community Insight
The key distinction lies in whether the device requires a computer connection after reboot; untethered does not, while tethered does.
This question defines the specific iOS jailbreak type that maintains its state across reboots without external assistance. The correct answer is D because untethered jailbreaking patches the kernel to persist permanently.
Many candidates confuse 'tethered' with 'semi-tethered' or 'untethered'. Option A is a common distractor because it involves patching the kernel, but it fails the 'no computer needed' criteria.

Expert Analysis
Why the Answer Is Correct
D (Untethered jailbreaking) is the correct answer because it allows the device to remain jailbroken after a reboot without any external tools or computers. The kernel is patched during the boot process so the jailbreak persists automatically.Why the Other Options Are Wrong
A (Tethered jailbreaking) requires a computer to run a tool every time the device boots to restore the jailbreak. C (Semi-tethered) typically refers to a state where the device can boot normally but lacks jailbreak features until a host application is used. B is often synonymous with semi-tethered in modern contexts, distinguishing it from the fully persistent untethered method.Community Comment Notes
Comments overwhelmingly support D, noting that untethered jailbreaks are permanent and do not require user intervention post-reboot. Some users like SukhoiF35 emphasize that the kernel patch happens automatically, unlike tethered methods which need manual triggering.Exam Strategy
When identifying jailbreak types, focus on the dependency after a reboot. If no computer or host software is needed, it is untethered. If a computer is required for every boot, it is tethered.
Frequently Asked Questions
What is the main difference between tethered and untethered jailbreaking?
Tethered jailbreaking requires a computer to be connected every time the device reboots to restore the jailbreak. Untethered jailbreaking persists automatically after reboots without external help.
Why is option A incorrect for this question?
Option A (Tethered) is incorrect because it implies the device loses its jailbroken state upon reboot unless manually restored via a computer connection, which contradicts the 'no assistance' requirement of the question.
