Kexec Tools for Android is a systemless root module that installs the official kexec-tools binary directly into your device. It enables users to directly boot a new operating system kernel from the running one without interacting with the bootloader.

I use this specific module when flashing custom kernels because it completely bypasses the traditional, time-consuming bootloader sequence. Since it packs multi-architecture binaries into a single zip file, you can drop it onto nearly any rooted phone and hot-boot an OS from the command line immediately.

Core Features

Systemless binary injection prevents permanent modifications to your actual device partitions while keeping commands easily accessible in /system/bin/.
Works across architectures natively, meaning you can run it on ARM64, ARM, x86_64, or x86 processors right out of the box.
Handling future updates takes zero effort since the module ties directly into Magisk’s built-in update mechanism.
Direct OS booting saves heavy development time by skipping standard firmware checks completely.

Support & Requirements

Required Root: Magisk v20.4 or higher.
Supported Architectures: ARM64, ARM, x86_64, and x86.

How to Install

Download the latest kexec zip release file to your phone's internal storage.
Open the Magisk app, navigate to the Modules menu, and select "Install from storage".
Tap the downloaded zip file to flash the binaries, then hit Reboot.
