Part 6: Post-Update Checklist – Making It Stick

Once the update successfully works, don't just assume everything is fine. Perform these final steps:

  1. Reinstall the necessary apps (Netflix, YouTube, Prime Video). Do NOT restore from a Google backup – fresh installs only.
  2. Check HDMI ports: Connect your PS5, Xbox, or set-top box to ensure ARC and CEC functions work.
  3. Re-calibrate picture mode – Firmware updates sometimes reset your brightness, contrast, and color settings.
  4. Disable telemetry (optional): Go to Settings > Privacy > Turn off "Send diagnostic data" to improve performance.
  5. Block auto-updates (optional): If you're happy with the current version, disable auto-update to prevent future forced updates that might reintroduce bugs.

Scenario B: Forced IMG Update (When Nothing Else Works)

Use this if your TV is stuck on the logo, won't boot, or you're getting "Update Failed" errors.

  1. Download the IMG file (e.g., V8-T586T01-LF1V634.img). It will be 1.5–2.5 GB in size.
  2. Rename the IMG file exactly to: MstarUpgrade.bin (case-sensitive).
  3. Copy MstarUpgrade.bin to the root of your FAT32 USB drive.
  4. Unplug the TV from power.
  5. Insert the USB drive.
  6. Locate the physical joystick/button on the back of the TCL 55C2US (usually on the bottom-left, behind the panel).
  7. Press and hold the Power button or the OK/Enter button on the joystick.
  8. While holding, plug the power cord back in. Keep holding for 10 seconds.
  9. A blue or white screen will appear with text: "Firmware updating, please do not turn off." Release the button.
  10. Wait 15–30 minutes. The TV will reboot automatically into a fresh Android TV setup.
