Brick saving method: short circuit 4R12 resistor.
Tools: A tweezers or other short lead, a dual male USB cable.
Steps to save bricks:
1. Disassemble the computer, and then open the Amlogic burning tool: USB_Burning_Tool, select and load the img file.
2. Then connect the USB cable to the USB port on the end of the set-top box close to the network card. Be careful not to connect the USB to the computer at this time! ! ! Never connect to the computer! ! ! There is no need to connect the power supply, because the computer USB comes with a 5V power supply.
3. Short-circuit the 4R12 resistor, and insert the USB cable into the computer with the other hand. At this time, the box will recognize the M304A hardware with a beep sound. At this time, loosen the tweezers as shown below:
4. Finally, click Start, and the progress bar will start to move. Wait for about 2 minutes, and you're done!
