I am sorry I can't write this in German, but that is really the reason for this post. I have read the thread to the best of my ability, but most of the German is beyond my understanding of the language. Appologies again.
I have worked out how to change the remote code on the DM7025+ and the DM800 to only respond to 0031 or 0032. However, I can only set the Dream button to one of these codes. The "TV" button will not accept 0032. Instead of blinking twice to show the code was accepted, it gives one long blink, which, I guess, means it failed.
The method used to update the dreambox is:
echo lvl > /proc/stb/ir/rc/mask0
where lvl is 0031 or 0032
I have also managed to change the remote for the "Dream" button to control 0032, but I cannot change the "TV" button to 0031.
Any help will be much appreciated.
