Hi enM and welcome to MRF.
What is the decoder you have in your loco? It will help to know.All new loco's comes with the default adress of 3.
77 is a bit odd. Try reseting the decoder value to factory preset values by writing 8 on CV 8 and see what happens.
Did you have Ecos read all the CV's from the decoder at the "advanced screen"?
Don't worry you'll have plenty of help here. You sure this is a new loco not a second hand one?
