Software for a CV638H-B universal TV main board, tagged with T55UHDS, the build string T1611-201 and the suffix EUS. CV638H boards are generic Android smart TV mainboards used by many small brands, so the firmware has to match the panel and the specific customer build. The 373 MB rar should contain an upgrade image for USB update or a dump for direct eMMC programming. Verify the board revision letter printed on the PCB and the panel resolution before use, and back up the existing memory with a programmer if possible.
