Note to myself, so I don’t forget. This is necessary after every OS update.

Note that not doing this does not invalidate rooted apps. But after updating, Magisk is not working any more, and with that we can’t manage root access to individual apps any more.

• Download the latest Magisk (.apk file)
• Rename to zip
• Boot into Recovery
• Start installation on Android device
• Install from computer with:
  adb sideload magisk-v25.1.zip
• Acknowledge unsigned app
