Can't access Settings after doing my Rebel 4 Settings mod?
You need to install ListLauncher. This is a launcher that adapts well to flip, and seems to work great.

Enabled "Install unknown apps" for File Manager
This can be enabled for any** installed app within Settings (Rebel 4) > Apps & Notifications > Special access > Install unknown apps.
**You still have to use fake-signed APKs. But sideloading your fake-signed APKs and updating your already-sideloaded APKs works and is also easier as you don't need to use ADB to sideload everything!

Once all prerequisites are met, go to the LG File Manager and pick this APK from your internal storage or SD card.

After installing, pressing (PWR/END) causes a menu to appear to choose FPHome or ListLauncher.
If you want this menu to appear, you are set. If not, here's how to set it to your preferred Launcher.
Go to Settings (Rebel 4) > Apps & Notifications > Default apps > Home app
Pick ListLauncher or FPHome.
I kept mine set to FPHome due to not being able to open the notification center through ListLauncher,
along with not wanting to have to pick ListLauncher or FPHome every time.
