To help you get your board up and running, please let me know:
: The hardware database does not recognize the storage chip. You may need to manually select the flash chip model or update the utility's definitions file.
Unlike standard USB firmware upgrades that require a functioning TV user interface, the ISP utility bypasses the operating system. It communicates directly with the onboard eMMC, SPI, or NAND flash memory through a hardware jig, allowing you to revive completely dead mainboards. Core Features of the Updated V5.0.8
Reduced waiting time during the ISP writing process.
: This means the software cannot talk to the chip. Check that your TV motherboard is receiving standby power (5V or 3.3V). Ensure your RX and TX lines are not flipped. Try lowering the I2C speed in the tool's setting menu. mstar isp utility v508 download updated
