Firmware archive for the CV358H-B42 universal TV mainboard, configured for 1 GB RAM and 8 GB storage with a 1366x768 panel, IR remote support and the MultyNet software build. The 403 MB RAR likely contains a USB update or eMMC image for Android smart TV boards of this family. Resolution and memory settings must match your panel and board, or the screen may stay dark or show a garbled picture. Keep the original firmware backed up and confirm the board marking before flashing.
