Note:

Please check the model carefully before upgrading the software, and reconfirm whether you need to upgrade the software. If you do not need to upgrade to solve the problem, please carefully choose to upgrade by yourself.

If the upgraded firmware model does not correspond, it will cause the product to crash and must be returned to the factory, and the chip needs to be reset with a computer.
The product upgrade process will take about half a minute. If the upgrade is interrupted during the upgrade, it will easily cause the chip to be upgraded to half of the CPU not working, and also need return to the factory.

HD820 upgrade method:

1. Format the U disk into fat32 format

2: Make sure that the USB flash drive is a USB flash drive that can play music or FAT32 format normally.

3: Copy the fileupdata.lin upgrade file to the root directory of the U disk (and please copy in a music file).

4: Switch the HD820 to the USB INPUT channel, and insert the U disk with the upgrade file directly in the power-on state.

5: When the U disk is upgraded, all the indicators will go out for a few seconds and then light up again. The same program will only be upgraded once
