Modern Combat 4 Invalid License Fix ((better)) -

Stop the Play Store or App Store from automatically updating or modifying the app files.

If you back up your game files to a PC or cloud drive, always back up the exact APK version that matches your OBB folder. Mixing versions triggers license and file validation errors.

Alternatively, Lucky Patcher now offers a "Make a license for app" feature that creates a fake license to bypass verification:

The licensing system relies on Google Play Store and Google Play Services. If their data is corrupted, every app will fail the license check.
