# TQ-pre-jailbreak

A **PRE**-jailbreak for iOS 14.0 ~ iOS 14.3 on all devices.

Generally speaking, jailbreak starts from an arbitrary kernel r/w vulnerability, so I name it pre-jailbreak. Actually, CVE-2021-1782(cicuta\_virosa) is the pre-jailbreak thing.

Implemented an arbitrary r/w primitive based on [cicuta\_virosa](https://github.com/ModernPwner/cicuta_virosa). Useful to security researchers, and jailbreak developers.

# Warranty

**Use it on your own risk**. I build it for security researchers only. **MEAN NOTHING** to normal users.

**DO NOT RUN IT** on you main device. I can not promise **WHAT WILL HAPPEN!**

# Current state

- [x] make the exploit faster (iPhone 12: 65s -> 10s, iPhone 6s: 188s -> 68s)

- [x] stable kernel r/w primitives

- [x] amfid bypass

Tested on iPhone 12 pro (**iOS 14.3**).

Tested on iPhone 11 (**iOS 14.0**).

~~Tested on iPhone 6s (**iOS 14.0**). Maybe helpful to A11 devices. I note that checkra1n said "Limited support for A11 devices on iOS 14.x".~~ I have upgraded the phone to iOS 15.0 beta.

~~For other devices/iOSs, add kernel offsets yourself in k\_offsets.c~~

Eliminate hardcoded variable offsets from kernelcache. No need to care about the offset things. Theoretically, works on every iOS \[14.0 ~ 14.3\] device.
