Hy,
einfach mal hier im Detail nachlesen wg "freischalten" D16, D8, LR9 mit EU-Versionen

The crucial bit!
This is important, your XJT module and any D16 receivers must match. Either both have EU firmwares, or both have non-EU firmwares. The D8 and LR12 mode receivers are not affected by this choice. If you're sticking with EU firmwares, then make sure to upgrade both the XJT and D16 receivers to the LBT firmware. The latest LBT firmware fixes some issues present in older EU firmwares.
How do I make it all work?
The simplest solution is to update your stock Taranis firmware to the latest OpenTX 2.1 branch without ticking the EU box in the Companion settings. OpenTX 2.0, while stable, is no longer developed.
The reason for this is that, despite FrSky's claim to have dropped D8 and LR12 modes from the EU firmware for the RF module, these modes actually still work. They were merely omitted from the mode selection in the operating system. The same is true if you have installed OpenTX with the EU option enabled.
I'm giving a couple of scenarios for likely combinations of old and new devices that you may have. Check the sticker in the module bay, it should tell you if your Taranis is an EU model or not.
For the EU Taranis with old and new receivers:
* Install the latest OpenTX firmware and do not enable EU-mode. You will be able to use all receivers types.
* If you also have D16 mode receivers from before 2015 make sure to update them to EU firmwares.
* The LBT firmware is recommended at this point.
Options for pre-2015 or non-EU Taranis with old and new receivers:
A. Upgrade any new D16 mode receivers to the last non-EU firmware, or
B. Buy an external EU XJT module for new D16 mode receivers, or
C. Upgrade the internal XJT module to the current EU version, and
1. Install the latest OpenTX firmware and do not enable EU-mode, and
2. Upgrade any old D16 mode receivers to match

* DHT ("Hack" module, D8 legacy protocols only)
....
Damit sollte klar sein,wie man die D8 zum laufen bringt,
Es war immer möglich, wie ich schon mehrfach schrieb.
NON EU, EU-MU10%, EU-LBT
Wenn man beim zusammenstellen der Optionen für openTx das eu ankreuzt werden unter openTx die Auswahl D8 und LR9 versteckt, nur D16 ist sichtbar.
Damit geht auch nur der Befehl für D16 an das XJT-Modul
Hier noch ein paar mehr Details
