Magisk

Installation

If you already have Magisk installed, it is strongly recommended to upgrade directly via the Magisk app using its “Direct Install” method. The following tutorial is only for the initial installation.

Getting Started

Before you start:


Download and install the latest Magisk app. We use the app to gather some information about your device. In the home screen, you should see this:

Pay special attention to the Ramdisk info. The result of this info determines whether your device has ramdisk in the boot partition.

(Unfortunately, there are exceptions as some devices’ bootloader accepts ramdisk even if it shouldn’t. In this case, you will have to follow the instructions as if your device’s boot partition does include ramdisk. There is no way to detect this, so the only way to know for sure is to actually try. Fortunately, as far as we know, only some Xiaomi devices are known to have this property, so most people can simply ignore this piece of information.)

If your device does not have boot ramdisk, read the Magisk in Recovery section before installing. The information in that section is VERY important!

If you are using a Samsung device and the SAR result is Yes, please check its own section.

Otherwise, continue to Patching Images.

(P.S.1: If your device has boot ramdisk, you can also install Magisk with a custom recovery, but it is not recommended)
(P.S.2: Huawei devices are not supported, and the instructions are removed from this page.)

Patching Images

If your device has boot ramdisk, you need a copy of the boot.img
If your device does NOT have boot ramdisk, you need a copy of the recovery.img.

You should be able to extract the file you need from official firmware packages or your custom ROM zip (if using one). If you are still having trouble, go to XDA-Developers and look for resources, guides, discussions, or ask for help in your device’s forum.

Uninstallation

The easiest way to uninstall Magisk is directly through the Magisk app. If you insist on using custom recoveries, rename the Magisk APK to uninstall.zip and flash it like any other ordinary flashable zip.

Magisk in Recovery

If your device does not have ramdisk in boot images, Magisk has no choice but to hijack the recovery partition. For these devices, you will have to reboot to recovery every time you want Magisk enabled.

Since Magisk now hijacks the recovery, there is a special mechanism for you to actually boot into recovery mode. Each device model has its own key combo to boot into recovery, as an example for Galaxy S10 it is (Power + Bixby + Volume Up). A quick search online should easily get you this info. As soon as you press the combo and the device vibrates with a splash screen, release all buttons to boot into Magisk. If you decide to boot into the actual recovery mode, long press volume up until you see the recovery screen.

As a summary, after installing Magisk in recovery (starting from power off):

(Note: You CANNOT use custom recoveries to install or upgrade Magisk in this case!!)

Samsung (System-as-root)

If your Samsung device is NOT launched with Android 9.0 or higher, you are reading the wrong section.

Before Installing Magisk

Unlocking Bootloader

Unlocking the bootloader on modern Samsung devices have some caveats. The newly introduced VaultKeeper service will make the bootloader reject any unofficial partitions in some cirumstances.

Instructions

Upgrading the OS

Once you have rooted your Samsung device, you can no longer upgrade your Android OS through OTA. To upgrade your device’s OS, you have to manually download the new firmware zip file and go through the same AP patching process written in the previous section. The only difference here is in the Odin flashing step: we do NOT use the CSC tar, but the HOME_CSC tar instead as we are performing an upgrade, not the initial install.

Important Notes

Custom Recovery

This installation method is deprecated and is maintained with minimum effort. YOU HAVE BEEN WARNED!

It is very difficult to accurately detect the device’s information in custom recovery environments. Due to this reason, installing Magisk through custom recoveries on modern devices is no longer recommended. If you face any issues, please use the Patch Image method as it is guaranteed to work 100% of the time.

Warning: the sepolicy.rule file of modules may be stored in the cache partition. DO NOT MANUALLY WIPE THE CACHE PARTITION.
