What this set can run

CJHelloVision SX930C_CJ runs Android TV, so it installs applications as APK files. CleanYourTV is a home-screen launcher for that system: a fixed grid of your apps, a clock and a dock, with no recommendation row and no account.

This page describes the platform the catalogue recorded, not the firmware details of one unit. Where a step depends on the manufacturer's build, the text says so instead of guessing.

The stock launcher can stay installed. Switching between them is a choice made with the Home button, not a reinstall.

How to install it

The full walkthrough, with the four methods that work without root, is the install guide linked from this page's model section. The short version:

1. Allow installs from unknown sources for the tool you will use — Settings → Security on Android TV, System → About on Google TV. The permission is per app, not global.
2. Install Downloader from the Play Store, open it, and paste the APK address shown on the download page.
3. Confirm the install dialog with the centre button of the remote. Play Protect may offer to scan the file; letting it scan is fine.
4. Open CleanYourTV once, press Home, and pick it from the list. Choose "Always" only after checking that the apps you need are in the grid.

How to install on a TV

Problems and error messages

"App not installed" is usually an architecture mismatch: nearly all Android TV boxes are ARM64, a few budget sets are 32-bit ARM only, and an arm64-only build installs partway and stops. Check the ABI under Settings → About before downloading again.

"Install blocked" or a greyed-out install button means the file manager or Downloader you are using never received the unknown-sources permission. Grant it to that one app and retry.

An app that installs but never appears on the home row did not register a launcher activity that this firmware accepts. Open it once from Settings → Apps, reboot, and it is normally listed afterwards.

A black screen right after launch points at an old system build. The launcher needs Android TV 8 or newer; the version is under Settings → About.

A download that finishes but will not open was truncated in transit. Download it again rather than retrying the same file.

Using the remote

The ring moves focus, the centre button selects, Back returns one level and Home leaves the app. Long-pressing the centre button opens the options menu in most launchers — on sets with no menu key that is the only way to reach it.

While an install dialog is open it is modal: press Back once to dismiss it before trying anything else, including Home.

Voice and assistant buttons belong to the manufacturer's system, not to the launcher, and keep working exactly as before. Nothing in the launcher remaps them.
