Running ADB and Fastboot directly from an Android device (often called "device-to-device" or "OTG debugging") allows you to flash images, debug apps, or manage other Android devices using a simple USB-OTG cable. Repacking your own module offers distinct advantages:
Ensure the filenames are strictly lowercase: adb and fastboot (with no extensions like .exe or .bin ). Step 3: Extract and Inject the Binaries
Always keep a copy of your stock boot.img or a Magisk uninstaller script on your computer before testing a newly repacked module.
You can optimize the module specifically for your target device's architecture (typically arm64-v8a ). adb fastboot magisk module repack
Select ( system , META-INF , module.prop , customize.sh ). Do not zip the parent folder itself; the internal files must sit directly at the root of the zip archive.
The process of "repacking" generally refers to modifying an existing module or a boot image and then re-compressing it for installation.

You might need to repack a Magisk module for several reasons: You can optimize the module specifically for your
customize.sh : An optional shell script executed by the Magisk app during installation. It handles custom permissions, architecture checks, and conditional file copying.
ADB is widely used in various scenarios, including:
