OK hab mal ein wenig gegoogelt, hier scheint die lösung zu sein:
Amiko SHD-8900 Alien – Dual boot Enigma2 firmware
As we touched on in the beginning the Amiko SHD-8900 Alien offers a dual boot option.
It is quite easy to use to switch from Spark to alternative Enigma2 software,
you simply press the OK button on the front of while turning on the box.
When it says Forc on the display you can choose which firmware to use by using the channel up down keys.
The receiver remembers your choice until you change it again.
Habs probiert, scheint zu klappen
EDIT
@googgi, wir haben uns überschnitten, danke für den Hinweis
Fehlt nur noch der Hinweis für zu leise Dolby HD Sender.
