Do themes work on Firmware X.X? / Themes don't work on X.X

The NXThemesInstaller will try to download the latest patches for your firmware version. Every FW update will break lockscreen themes. If a firmware update released only recently, it may take some time for the developer to release the required patches. The application will download them as soon as they are available. You need internet, so make sure you’ve set up Atmosphere’s dns mitm or 90dns, or install them manually from here.
