The standby LED light on the TV should begin flashing rapidly (alternating between red and blue/green). This indicates that the board is reading the firmware and writing it to the EEPROM/Flash IC. Release the power button once the blinking sequence begins.
If the standby light never blinks and the TV boots normally into its glitched state: Try a smaller USB drive (4GB or 8GB). Ensure the drive is formatted to FAT32.
If the USB method completely fails because the bootloader itself is corrupted, you will need to perform an ISP (In-System Programming) flash. This requires opening the TV, clipping an EEPROM programmer (like the CH341A or RT809H) onto the 8-pin flash memory chip on the ZL782-MB-V2.1 board, and burning the firmware directly using a computer.
