Hello Guys, I have already seen couple of topic related to the skoda system updates but non of them started with soft. nr. 1668. Lately i went to some guy who is "specialized" in Skodas software and he was trying to do the large upgrade from 1668 to 1985 but installation awlays stuck at 0%. Visiting plenty of different webistes and forums i noticed that many people mentioned that soft upgrade should be done step by step like from 1668 to 17xx then to 18xx etc etc. What the funny thing is when i enter engineer mode system shows me that i have 1985 but if i go to the settings it shows 1668 and i dont know how to start. Could you guide me ? Thanks!
