Root Android with Magisk

Introduction

Magisk¹ is a suite of open source software for customizing Android, supporting devices higher than Android 5.0.

Some highlight features:

• MagiskSU: Provide root access for applications
• Magisk Modules: Modify read-only partitions by installing modules
• MagiskBoot: The most complete tool for unpacking and repacking Android boot images
• Zygisk: Run code in every Android applications' processes

This is my notes on installing it on my op6 following the official installation guide.

Download and install Magisk app

Download latest Magisk apk from github release. Install it:

1

adb insatll Magisk.apk

After launching the app, notice the Ramdisk value (mine is Yes), it means whether or not your device has boot ramdisk.

• if Yes, patch boot partition (I’ll choose this)
• if No, patch recovery partition

backup images

This will need root access, so reboot to twrp recovery first.

# go to twrp recovery to get root access to your image partition
# adb reboot recovery
adb shell # commands below are executed in the android shell
# get current slot (A/B)
/bin/getprop ro.boot.slot_suffix
# _a, so I will backup /dev/block/by-name/boot_a
dd if=/dev/block/by-name/boot_a of=/sdcard/boot.img
# optional, if you have vbmeta partition
# dd if=/dev/block/by-name/vbmeta_a of=/sdcard/vbmeta.img
# adb pull /sdcard/vbmeta.img

patch image and install

patch image inside magisk app.

• press install button in the magisk card

pull the patched image to your computer, reboot to bootloader, flash the new patched image to your android device.

Now open Magisk app again, you can see it’s installed.
