NanoDroid for lets you pseudo-debloat the ROM, install microG, F-Droid, FOSS apps, GNU Bash, GNU Nano, Zelda ringtones and sounds. NanoDroid is a installer for various OpenSource related things, most noticably microG and F-Droid. It supports direct /system installation, both devices with or without A/B partition scheme, aswell as Magisk Mode (module) installation. It also includes several tools (eg. GNU Bash, GNU Nano, more), scripts, fonts, sounds and additional features (system debloating, init scripts, automatic logcat creation), aswell as a companion F-Droid Repository. NanoDroid allows you to choose between the official microG GmsCore and a custom microG GmsCore (default). In order for full microG experience NanoDroid contains a modified Play Store which allows (in-)app-purchases with microG, which would normally not be possible. It also tries to remove all previously installed GApps on it's own. For ROMs without builtin signature spoofing support NanoDroid includes an on-device Patcher which tries to patch your ROM from TWRP.
