USB Firmware Upgrade (USB Format FAT32)

plug into PROG USB port.
2. Press and hold ENTER+DOWN button for about 3 seconds until the two HDBT/HDMI
INPUT LEDs are lit, and then release buttons.
the device enters USB mode and firmware upgrade starts.
Upon completion (after about 30 seconds), the device reboots.
If the device is in USB mode but can’t read the firmware file or if the USB flash driver is not
connected, it reboots automatically after 10 seconds and exits the USB mode.
If the power drops during firmware upgrade, it automatically starts upgrading once the power
is back.
If the power drops in the early stages of firmware upgrade, you need to start firmware
upgrade again.
