Thanks Frenske, but I am now confused.....
When using OpenPli 6.2 the security board is inactivated (works even without battery) and this is also the same in OpenPli 7.0?
I'm referring to the post April 24 2018:

Great news for all (former) Xtrend users. Securitycheck removed.
Securitycheck removed from several, possibly all Xtrend models.
Due to the failure of the Securityboard and the fact that Xtrend / NexTV wasn’t able to help their users quite a few Xtrend STB’s landed in the trashbin. It now appears that this problem suddenly seems to be solved in the latest drivers. Besides solving the annoying problems with the et8000 / et10000 now also the security check is disabled in those new drivers. Those specific drivers are available from OpenPLi 6.2. The result is that many (former) Xtrend users still can use their old set-top box again.

and also to a link in the Nachtfalke forum where someone tested an ET9000;
