Uninstallation - LemonLoader/MelonLoader GitHub Wiki

With Lemon 0.2.0+, the installer now has a system to backup and restore unpatched APKs.

In order to take advantage of this feature, you will need to patch a previously unpatched version of the game (basically, patch a clean install to set it up).

To restore back to the clean copy of the game, click on it in the installer, then press "Restore Unpatched APK" located at the bottom of the screen.

If you did not use this feature, the only way is to reinstall the game.
