HD920 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 (please copy in a music file).

4: Switch the HD920 to the USB INPUT channel, and insert the U disk with the upgrade file directly in the power-on state.

5: After inserting, wait a few seconds for a white screen to appear on the display, wait for more than ten seconds to exit, and the upgrade is complete.

PS: If the system firmware of the machine is the latest, it will automatically skip the upgrade and play the music in the USB flash drive. If there is no music file in the USB flash drive, it will stop in the white screen because the content cannot be read. Please restart and remove the USB flash drive.
