Install-LineageMagiskPatchedBootImage PowerShell script

PowerShell script to download current LineageOS build, extract boot image, patch with Magisk, and flash patched boot image to Android device.

Based on a bash script by NicolasWebDev, which itself is based on the Magisk installation guide.

Due to the lack of native USB support in Windows Subsystem for Linux (WSL), I ported the script to PowerShell and added some additional error checking for Windows users to easily upgrade LineageOS and repatch the boot image with Magisk.

Usage

1. Open 'Settings > System > Updater' on your LineageOS device. Download and install an update.

2. Reboot device and Magisk will show as no longer installed.

3. Connect your device to your computer.

4. Open a PowerShell prompt on your computer.

5. Download or clone the repository.

   PS> git clone http://github.com/richardlock/Install-LineageMagiskPatchedBootImage

6. Get the device serial number of the connected LineageOS device.

   PS> adb devices
   List of devices attached
   ABCD123456 device

7. Execute the script specifying the device serial number.

   .\Install-LineageMagiskPatchedBootImage.ps1 -DeviceSerialNumber 'ABCD123456'
