Yes, the steps are clear to me, i did it as you say, and it's not the first box i updated with LE. I get this box running with the dtds from the list, but only wifi works. Ethernet works only with Android-FW.
With none of the existing dtd-files I get the ethernet of my box to work. I have extracted the dtd from the original firmware, but LE does not start with this file. How do I get it to work with the extracted dtd?
