Magisk

Installation

If you already have Magisk installed, it is strongly recommended to upgrade directly via Magisk Manager. The following tutorial is for first time users.

Prerequisite

Custom Recovery

If your device have custom recovery support, the easiest way is to install it through custom recoveries, such as TWRP.

Boot Image Patching

This is the “cool” way to install Magisk on your device. Either your device does not have proper custom recoveries, your device is using the A/B partition scheme and you don’t want to mix recovery and boot images together, or you have other concerns (e.g. OTA Installation), you should use this method instead.

In order to use this method, you are required to obtain a copy of the stock boot image, which can be found by extracting OEM provided factory images or extracting from OTA update zips. If you are unable to obtain one yourself, someone on the Internet might share it somewhere. The following instructions will guide you through the process after you have the copy of boot image.

Magisk in Recovery

Due to the fact that some devices no longer uses ramdisk in boot images, Magisk has no choice but to be installed in the recovery partition. For these devices, you will have to boot to recovery every time if you want Magisk. Since both Magisk and recovery lives in the same partition, what you actually end up getting when you choose to boot to recovery will be determined by how long you press volume up.

Each OEM has its own key combo to boot into recovery. For example on Samsung it is (Power + Bixby + Volume Up), and for Huawei it is (Power + Volume Up). As soon as you press the combo and the device vibrates with a splash screen, the bootloader has already chosen which mode it is booting, either it be boot, recovery, or some OEM specific modes like download, fastboot, or erecovery. After the splash screen, release all buttons to boot into Magisk, since by default recovery mode will boot to the system with Magisk enabled. If you decide to boot to actual recovery, continue to press volume up until you see the recovery screen.

In summary, after installing Magisk:

Samsung (System-as-root)

If your device is NOT launched with Android 9.0 or higher (released after 2019), follow the normal tutorial

Before Installing Magisk

Unlocking Bootloader

Normally I won’t provide instructions for this, but since things had changed drastically from previous Samsung devices, and there are some details that many might not know, I figure this would be helpful.

Just when you think the bootloader is unlocked, surprise surprise, it is actually not! Samsung introduced VaultKeeper in the system, meaning the bootloader will reject any unofficial partitions before VaultKeeper explicitly allows it.

Instructions

  1. Download the firmware for your device.
  2. Unzip the firmware and copy the AP tar file to your device. It is normally named as AP_[device_model_sw_ver].tar.md5
  3. Install the latest Magisk Manager
  4. In Magisk Manager: Install → Install → Select and Patch a File and select the AP tar file.
  5. Magisk Manager will patch the whole firmware file and store the output to [Internal Storage]/Download/magisk_patched.tar
  6. Copy the tar file to your PC (using adb: some people report corruption using MTP), and boot your device to download mode.
  7. Flash magisk_patched.tar as AP in ODIN, together with the BL, CP and HOME_CSC files. Never flash only an AP file, as Odin can shrink your /data file-system if you do.
    Important: Uncheck “Auto Reboot” in Options!
  8. Magisk is now successfully flashed to your device! But there are still several steps before you can properly use the device.
  9. We now want to boot into the stock recovery to factory reset our device.
    Full data wipe is mandatory! Do not skip this step.
    Press Power + Volume Down to exit download mode. As soon as the screen turns off, immediately press Power + Bixby + Volume Up to boot to recovery partition. Just as mentioned in the previous section, since we want to boot into stock recovery, continue pressing the volume up button until you see the stock recovery screen.
  10. In the stock recovery menu, use volume buttons to navigate through menus, and the power button to select the option. Select Wipe data/factory reset to wipe the data of the device.
  11. This time, we can finally boot to the system with Magisk. Select Reboot system now, and immediately press Power + Bixby + Volume Up. After seeing the bootloader warning screen, release all buttons so it can boot to the system.
  12. The device will automatically reboot for the first time it boots. This is completely normal and done by design.
  13. After the device is booted up, do the usual initial setup. The following steps will need internet connection.
  14. You shall see Magisk Manager in your app drawer; if not, manually install the APK you downloaded in step 3 and continue to the next step. The app would be a stub and it shall automatically upgrade to the full Magisk Manager when you open it.
  15. Magisk Manager will ask to do additional setups. Let it do its job and the app will automatically reboot your device.
  16. Voila! Enjoy Magisk :)

Additional Info

Huawei

Huawei devices using Kirin processors have a different partitioning method from most common devices. Magisk is usually installed to the boot partition of the device, however Huawei devices does not have this partition. Depending on what EMUI version your device is running, the instructions will be slightly different.

Obtain Stock Images

Huawei does not release official factory images, however most firmware zips can be downloaded from the Huawei Firmware Database. To extract images from UPDATE.APP in the zip, you have to use Huawei Update Extractor (Windows only!)

EMUI 8

For EMUI 8 devices, your device have a partition named ramdisk, which is where Magisk is going to be installed.

EMUI 9 or Higher

For EMUI 9+ devices, the ramdisk partition no longer exists. As a workaround, Magisk will be installed to the recovery_ramdisk partition. Please read the Magisk in Recovery section before following the instructions below!

Note: As I tested on my Honor View 10, Huawei’s kernel does not seem to be able to capture key button press events in early boot, so long pressing Volume Up does NOT boot to recovery on my device. Your experience may vary.
