If the internal bootloader is completely corrupted, the USB ports will not register. Technicians will need an advanced specialized ISP/eMMC hardware programmer like the UFPI Programmer or RT809H.
If the TV is completely dead (bricked) and cannot read a USB port, technicians use hardware programmers like the UFPI Programmer or RT809H. This method requires soldering directly to the ISP points or desoldering the Toshiba eMMC chip to flash the raw data partitions, which include system , userdata , tvos , and boot .
