Adb: Fastboot Magisk Module Repack

To replace a system app systemlessly:

my_module/
└── system/
    └── app/
        └── MyApp/
            └── MyApp.apk

No extra scripts needed – Magisk overlays at boot.

Open module.prop in your text editor. Change it like this: adb fastboot magisk module repack

id=systemless_hosts_repacked
name=Systemless Hosts (Repacked)
version=v1.2
versionCode=120
author=YourName (Forked from OriginalAuthor)
description=Blocks ads via hosts file. Repacked with custom boot script.

Tip: The id must be unique and lowercase with no spaces.

Edit module.prop (change version, description, etc.)
Add/overlay files in system/ (e.g., system/etc/some_config)
Update or add scripts (post-fs-data.sh must be executable) To replace a system app systemlessly: my_module/ └──

To add custom sepolicy.rule:

# Generate from boot image patching (outside scope)
# Place inside module root as sepolicy.rule

To "repack" a module, one must understand what is inside the container. A Magisk module is essentially a standard ZIP archive with a specific file structure. When you unzip a module, you typically find: No extra scripts needed – Magisk overlays at boot
