USB firmware set for the CV9256-B42 universal TV board, configured for a 1366x768 panel and a 300 mA backlight current. The RAR is about 797 MB and should be extracted and copied to a USB drive, then loaded through the board's update procedure. With universal boards the panel resolution and LED current both have to suit the installed display, or you may get no picture or overstressed backlight strips. Check the board marking and panel label before use, and back up the existing firmware.
