To be able to install them (when moving from official discord app), you'll need to first uninstall Discord app and restart your device. You may also need to enable play protect.
You can just update directly from APKs there once you do that, so this is a process you only need to do once.
- Get a Discord apk (*cough* [apkmirror](https://www.apkmirror.com/apk/discord-inc/discord-chat-for-gamers/), [aptoide API](https://ws75.aptoide.com/api/7/app/getMeta?package_name=com.discord)).
- Get all the necessary patches for that version. Necessary patches are not available for all versions and are only required to get some versions to pack together correctly.
- Get optional patches you want for your version. If the patch you want isn't available for your version, you'll have to port them yourself.
