You should be using a Custom Nougat ROM (7.1.1 only) that has full support for OMS for this theme to work. THIS WILL NOT WORK ON A STOCK ROM!!! You must also be fully rooted or have a ROM with rootless commits and have the Substratum App.

===========================
INSTALLATION INSTRUCTIONS:

1. Download & install the theme.
2. Open Substratum App.
3. When Substratum is opened give it full root permissions and also allow system modifications.
4. Click on the theme and wait for it to create the resource caches then click on the theme again.
5. Inside theme check the switch; Select to toggle all overlays'. Alternatively you can click on the overlays that you would like to install (keep in mind that some apps mainly Android system have different variants that you can choose).
6. Click the floating action button (FAB) down the bottom and select Build & Enable.
7. Once that finishes compiling/installing with no errors wait until SystemUI restarts.
8. Enjoy your new Lovable dark UI .
