So I see the CH341a, but what are the other two PCBs that are stacked on top that the ribbon cable is connected to? And how did you find out you needed them?
Overall, that’s awesome work! Couldn’t have broken it any worse than it was, so why not take the chance and it paid off.
A lot of movies go through rewrites and updates before they get released, so saying it’s bad now may not be indicative of the final product. I mean look at Sonic. If that movie got released during its unfinished phase everyone would have hated it. That’s why they do test screenings and ask for feedback before release. Sometimes the movie will drastically change from its original.
