Verdict
No known root. You can still tame it via the local SmartCast API. Community docs mention port 9000.
The 2021 SCPL root (CVE-2021-27944 / CVE-2021-27942) is patched. Do not chase old bootloader-replacement guides; they do not apply to current Walmart Vizio sets.
How to
- Pair: start pairing, enter the on-screen PIN, store the auth token (do not share it).
- Turn off Viewing Data (ACR) and limit ad tracking; settings paths vary by model; see sources.
- Set power-on to last input so the TV boots straight to HDMI (pairs with the Fire TV Stick 4K 1st gen entry).
We do not host binaries or exploit code. Use the SmartCast API docs linked in sources.
