Tips: Recommend you use SD card brush. The method is that copy SD flash firmware 1,2,3 to the SD card root directory, and then put the SD card on the machine, plug in the power supply. Continuously press the remote control on the number 1 key, then you can automatically enter the state of the brush machine.
