If no official update is available, you can still improve performance and features: How to Update System Software in your SMART TV?
Q: Will this update remove ads from my home screen? A: No. The update is for performance, not ad removal. However, the faster UI makes skipping ads less painful.
Q: My TV is not a CVTE brand. Can I still use this?
A: If your main board has an MSD338 chipset (check via CPU-Z for TV), yes. But it is safer to get the branded version (e.g., Hisense_MSD338_upd).
Q: The update failed. Is my TV permanently broken? A: Unlikely. Most CVTE boards have a "boot recovery" mode. Download the original firmware from the manufacturer and repeat the USB method. If that fails, you can buy a replacement main board for the MSD338 on eBay for roughly $25.
Q: Does this enable 120Hz refresh rate? A: No. The MSD338 chipset is physically limited to 60Hz. This update optimizes motion interpolation (smoothing), but it does not change the hardware refresh rate.
