Hab die Datei vom Hersteller bekommen.
Wer Interesse hat kann mir seine email Adresse schicken.
Sende es dann zu.
Hier die Anleitung:
Please unzip the file first
1) save the update files into the SD card root directory ( filename must not be changed)
2) remove the power cable from Mr12Volt adapter
3) insert SD card into the SD slot that is below the optical input
4) connect the power cable, the update will start automatically. ( during update , the red and blue lights will blink together continuously)
5) if the update is successful, the blue led will remain on at the end ( if not successfully updated, the Red Led shows finally)
Repeat the same procedure again if first time is not successful
6) after update, disconnect the power cable FIRST then remove SD card and do a reset
